Keep that Michelle went out To dinner. The total cost of the meal, including the tip, came out to $53.70. It's a combined tip came out to $9.60 and each friend spent an equal amount, how much did each friend pay not including the tip?
The question is incomplete:
Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?
Answer:
Each friend paid $22.05 without including the tip.
Step-by-step explanation:
Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:
$53.70-$9.60=$44.1
$44.1/2=$22.05
According to this, the answer is that each friend paid $22.05 without including the tip.

part d does this curved line represent a function? if not, at what points does it fail the verticals line test ?
Answer:
It does not represent a function.
It fails at (3,1), (3,-1), (3,-3.5). The points are variable, the x must stay the same to ensure you tested for VCL.
Step-by-step explanation:
The vertical line test is the easiest test to see if a line is a function. All you have to do is draw a vertical line across the "function". If AT ANY TIME, the vertical line intersects more than once with the "function", it has failed the vertical line test (VLT) and is not a function.
Please look at the image attached to see how to do the VLT. Please ignore my line drawing and mouse-writing :)
Answer:
This curved line is not a function. Two points where it fails the vertical line test are (3, 1) and (3, -1).

f(x) =∛2x g(x)=2x+1 Find (f/g) (x) Include any restrictions on the domain
Answer: ∛2x / 2x+1
x cannot equal -1/2
Step-by-step explanation: f/g means we divide the f function by the g function
so that’s all we do!
then, remember, we can’t divide by 0. so 2x+1 can’t be 0. if we solve that out, we get that x can’t be -1/2, because that would make it 0. there’s our domain restriction!

MATH HELP!!!! I HAVE POSTED THIS QUESTION AND NO ONE ANSWERS! 15 POINTS!!!
Answer:
A
Step-by-step explanation:
in order to find the answer take into mind what the question is asking for.
The equation has to pass the point (12,3) and has to be parallel to y=(4/3)x+5.
since the equations have to be parallel you can take out D since it has the reciprocal of the slope of the original equation.
You could also take out the negative equation C since the original one is not negative.
then you would have to graph the equations and would find that A is the answer because in order to have a point (12,3) you need to either start from the negative y-axis and ascend or from the positive axis and descend but B doesn't go down it goes up since it has a positive y value and has a positive slope. So in conclusion the answer would be A.
[tex]y = \frac{4 }{3} x - 13[/tex]

Lines / and m parallel. Can be represented by the 3x+4y=8. If line m passes thorough the point (2,-5), which equation can be used to find the equation of line m
Answer:
y=−34x+2.75
Step-by-step explanation:
Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form.
3x + 4y = 12
4y = –3x + 12
y = –(3/4)x + 3
slope = –3/4
We know that the second line will also have a slope of –3/4, and we are given the point (1,2). We can set up an equation in slope-intercept form and use these values to solve for the y-intercept.
y = mx + b
2 = –3/4(1) + b
2 = –3/4 + b
b = 2 + 3/4 = 2.75
Plug the y-intercept back into the equation to get our final answer.
y = –(3/4)x + 2.75

IM Commentary
The purpose of this task is to help students
Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left (5.NBT.1)
By setting the task in the context of weighing objects and bundles of 10, 100, and 1,000 objects, it helps students visualize that bundling 10 units of a given place value will create 1 unit of the next highest place value. For example, taking 10 of an item that weighs 4.2 grams will result in 42 grams because it is 10 groups of 4 grams that weights 40 grams all together, and 10 groups of 0.2 grams that weigh 2 grams all together. The task allows students to explore both the structure of our place value system and how we use that to efficiently multiply and divide powers of 10.
Though this task is written as questions to be discussed or answered by students, the parts of this task are most valuable as a set of scenarios to be infused throughout a unit on place value. The teacher can actually bring in a digital scale and go through a series of explorations with students. It might be natural to start with students weighing one object and making predictions about how much 10 or 100 of these objects would weigh. From there, the teacher may want to have students start weighing sets of 10 or 100 objects and work backwards to think about the weight of 1 object.
The digital scale has several advantages: the weight will always appear in decimal form, thereby making it perfect for students to start reasoning about shifts in decimal place value from a more intuitive place. Moreover, the digital scale will not always show the expected answer. For example, something that weighs 3.5 grams alone might weigh 35.4 grams (rather than 35 grams) when taken as a group of 10. This slight difference provides an excellent opportunity to talk about rounding error. It also requires students to think beyond the rules of sliding a decimal point to the right when multiplying by powers of 10.
If students were still developing the rules for multiplying and dividing by powers of 10, this task would also incorporate MP8, Look for and express regularity in repeated reasoning. It also incorporates parts of MP6, Attend to precision, in that a higher-level discussion will push students to reason why one marshmallow might weigh 7.2 grams, but 10 marshmallows might weigh 7.19 grams. See the solution for part (a) for further elaboration.
Solution
Solution:
10 marshmallows should weigh 72 grams. Students might use repeated addition, multiplication or reason that each digit’s place value will be multiplied by a factor of 10:
10×(7+0.2)(10×7)+(10×0.2)70+272===
If students have had practice using digital scales in class, some students might respond with guesses that are close such as 73 grams or 72.4 grams because the original 7.2 grams may have been rounded to the nearest tenth. If, for example, the original actual weight were 7.24 grams, then the weight of ten marshmallows on a scale that rounds to the nearest tenth of a gram would be 72.4 grams.
1 jellybean should weigh 1.2 grams. Students may come to the solution a number of ways.
Students might notice that dividing 12 by 10 could be expressed in fraction form 1210. Students might further reason that
1210=1010+210
or 1.2.
Students might alternately reason that 12÷10 is the same as
(10÷10)+(2÷10)=1+0.2=1.2
Students might also use the rule that they are beginning to develop about sliding the decimal point one place to the left to divide by 10.
1,000 pink erasers should weigh about 31,240 grams. Students may come to the solution a number of ways:
A student might reason that first, it would be necessary to find out what 100 erasers would weigh by multiplying by a factor of 10 and then further multiplying by another factor of 10 to find out what 1,000 erasers would weigh. This is represented by
312.4×10×10
In this solution method, the student reasoned that multiplying by a factor of 10 and then another factor of 10 would be the same as multiplying by a factor of 100:
312.4×10×10312.4×100100×(300+10+2+0.4)30,000+1,000+200+4031,240====
Another student might want to find the weight of a single eraser. If 10 erasers weigh 312.4 grams, then one eraser must weigh 31.24 grams. From there the student could multiply the weight of one eraser by a factor of 1,000:
1000×(30+1+0.22+0.04)30,000+1,000+200+4031,240==
Step-by-step explanation:
You would expect 1,000 pink erasers to weigh 31,240 grams.
If 10 erasers weigh 312.4 grams, and to get 1,000 you multiply by 100, if you multiply 312.4 by 100 you get 31240.
Or if you use rates
[tex]\frac{312.4}{10} =\frac{31240}{1000}[/tex]
(when you multiply by 100)

Video Games With an initial cost of $ 5000, a company will produce x units of a video game at $ 25 per unit. Write an equation that relates the total cost of producing x units to the number of units produced. Plot the cost of producing 100, 150, 200, 250, and 300 units.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= $5,000
Unitary variable cost= $25
First, we need to structure the total cost formula:
Total cost= fixed costs + unitary cost*number of units
Total cost= 5,000 + 25*x
x= number of units
For 100:
Total cost= 5,000 + 25*100= $7,500
For 150:
Total cost= 5,000 + 25*150= $8,750
For 200:
Total cost= 5,000 + 25*200= $10,00
For 250:
Total cost= 5,000 + 25*250= $11,250
For 300:
Total cost= 5,000 + 25*300= $12,500

Answer:
Step-by-step explanation:
To find the center and the radius, we need to put the equation in the (x-a)^2+(y-b)^2=r^2 [a is the x-coordinate, b is the y-coordinate, and r is the radius].
(x+6)^2+(y+7)^2 - 36 - 49 + 69 = 0
(x+6)^2+(y+7)^2 - 16 = 0
(x+6)^2+(y+7)^2 = 16
(x+6)^2+(y+7)^2 = 4^2
The center is (-6,-7) and the radius is 4.

Equation:
Value of X:
Angle measures: __ & __
Equation : (7x + 9) + (5x + 3) = 180°
The two lines, say, line a and b are parallel and line y is a transversal. The two angles are called supplementary angles.
_________________________________
To find the value of x, we need to solve the equation.
(7x + 9) + (5x + 3) = 180
7x + 9 + 5x + 3 = 180
(7x + 5x) + (9 + 3) = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x = 168/12
x = 84/6
x = 42/3
x = 14
Value of x: 14
_________________________________
First angle = 7x + 9
= 7×14 + 9
= 98 + 9
= 107
Second angle = 5x + 3
= 5×14 + 3
= 70 + 3
= 73
Angle measures: 107° & 73°
