A store is instructed by corporate headquarters to put a markup of ​25% on all items. An item costing 8​$ is displayed by the store manager at a selling price of ​2$. As an​ employee, you notice that this selling price is incorrect. Find the correct selling price. What was the​ manager's likely​ error?

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).

2. $350

3a: 15 is half of 30, so knowing that means the answer is 50%

3b. 3 is 1/4 of 12 because 3x4 is 12, meaning that 3 is 25% of 12.

Answer:

$40

Step-by-step explanation:

Brian starts at $100, then loses 1/4th of the money,

100/4 = 25,

then you subtract 25 from 100, which gives you 75

With the remaining $75, he spends $15 on girl scout cookies,

75 - 15 = 60

He then has $60 remaining, but while walking home, loses 1/3 of the total amount.

60/3 = 20,

you then subtract 20 from 60, which gives you 40

Therefore, $40 is what is remaining.

Answer:

The Answer is -11 cause its just -11

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.

If the function is translated using the rule (x + 1, y – 2), the resulting function will be g(x) = (x+1)² -2

Translation is a way of changing the position of a figure on an xy plane. Given the parent function

y = x²

If the function is translated using the rule (x + 1, y – 2), the resulting function will be g(x) = (x+1)² -2. The equivalent graph if the function is as shown  below.

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.

Answer:

a = b = 40°

Step-by-step explanation:

∠ a and 140° are adjacent and are supplementary , thus

a = 180° - 140° = 40°

a and b are alternate angles and are congruent, thus

b = a = 40°

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

Answer:

did you simplify them??

Step-by-step explanation:

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°

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.
