Answer:
-2 and -3
Step-by-step explanation:
a negative multiplied by a negative is a positive so -2 multiplied by -3 equals 6. And, -2 + -3 = -5
I don't understand this
1. This equation shows how the total number of appetizer recipes Carly knows depends on the number of weeks she attends culinary school. a = 2w. The variable w represents the number of weeks she has attended culinary school, and the variable a represents the total number of appetizer recipes she knows. After how many weeks of culinary school will Carly know a total of 8 appetizer recipes? *
Answer:
16 weeks
Step-by-step explanation:
Set up a proportion with the equation.
a = 2w
8
2 x 8= 16 then 16/1=16
so she was at school for 16 weeks.

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+5y=-7
-3x +14y=-18
Answer:
One solution:(-8,-3)
Step-by-step explanation:
x = 5y + 7
Plug this in for variable x in equation [2]
[2] -3•(5y+7) + 14y = -18
[2] - y = 3
Solve equation [2] for the variable y
[2] y = - 3
By now we know this much :
x = 5y+7
y = -3
Use the y value to solve for x
x = 5(-3)+7 = -8
Solution :
{x,y} = {-8,-3}
Hope this helps plz mark brainliest if correct :D

Step-by-step explanation:
A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth. Enter your answer in the box.
Answer:
2.9 minutes
Step-by-step explanation:
Given
[tex]Rate = 12 gallon/minute[/tex]
[tex]Size = 35\ gallon[/tex]
Required
Determine the time spent
The rate is a ratio of size to time
So, it can be expressed as:
[tex]Rate = \frac{Size}{Time}[/tex]
Substitute values for Rate and Size
[tex]12 = \frac{35}{Time}[/tex]
Cross Multiply
[tex]12 * Time = 35[/tex]
Solve for Time
[tex]Time = 35/12[/tex]
[tex]Time = 2.9[/tex] (approximated)

Answer:
1.___ b
2.___c
3.___a
4.___d
Step-by-step explanation:
5% of x is =8
5/100 * X= 8
x=8*100/5=800/5=160
12% of x =5
x=41.666 approximately
8% of x=12
x=12*100/8=1200/8=150
5% of x= 12
x=12*100/5=1200/5=240

Which relations are functions? Select all that apply.
Answer:
A and C
Step-by-step explanation:
B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.
For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.
In answer A, no domain is repeated in any of the points making it a function.
In answer C, again no domains are paired with more than one range making it a function. That why A and C are the answers

In order to safely clear a hurdle, a track runner must jump the hurdles with an angle of 30°. Find the height of the hurdle and the horizontal distance traveled if the runner covers a distance of 5 feet
The hurdle and runner form a right triangle (see attached picture) such that
sin(30°) = h / (5 ft)
and
cos(30°) = x / (5 ft)
where h is the height of the hurdle and x is the horizontal distance from where the runner jumps to the hurdle. So
h = (5 ft) sin(30°) = 5/2 ft = 2.5 ft
x = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
Prove the theorem: In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other. Given the facts RS ⊥ CD and AB || CD, drag and drop each reason next to the appropriate statement in order to prove the statement RS ⊥ AB.
Answer:
The theorem requiring proof;
A transversal perpendicular to one of two parallel lines is also perpendicular to the other parallel line
The two column proof is as follows
Statement [tex]{}[/tex] Reason
RS ⊥ CD [tex]{}[/tex] Given
AB ║ CD [tex]{}[/tex] Given
The Slope of AB = The slope of CD [tex]{}[/tex] definition of parallel lines
The Slope of RS = -1/(The slope of CD) [tex]{}[/tex] definition of perpendicular lines
The Slope of RS = -1/(The slope of AB) [tex]{}[/tex] transitive property of equality
The Slope of RS = -1/(The slope of AB) [tex]{}[/tex] definition of perpendicular lines
RS ⊥ AB

Answer:
x = -9
Step-by-step explanation:
multiply 2 on both sides which cancels out the 2 in the fraction and then do -1 times 2 and 2 times x (which is just 2x). After doing that your equation should look like 3x + 7 = 2x - 2
Collect your like terms (the numbers with an x variable go togther and the ones with an x have to be together) and rearrange it so it looks like: 3x - 2x = -2 - 7 after you have this written subtract 3 from 2 now because they're on the same side which leaves you with x (usually we leave out the one because it doesn't make a difference) so now you're left with x = -2 - 7 for this step subract -2 from 7 which leaves you with x = -9
Steps:
3x + 7 = 2x - 2
3x - 2x = -2 -7
x = -2 - 7
x = -9

Find the measure of ∠z.
A.120°
B.30°
C.40°
Answer:
B. 30
Step-by-step explanation:
The angle is 90 degrees total
The picture says z + 60 = 90
z = 30
Answer:
B. 30
Step-by-step explanation:
The angle on the other side is 90 degrees. That means that the angle on this side has to be 90 degrees. Part of it is 60, so that means that the other is 30 degrees.
The Collatz conjecture is one of the most famous unsolved mathematical problems, because it's so simple, you can explain it to a primary-school-aged kid, and they'll probably be intrigued enough to try and find the answer for themselves.
Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.
Explanation:
Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:
An even number (eg 2, 4, 6,...), then if they are divided by 2, the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=1)An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.Given the function f(x) = x^2, which of the following represents a vertical shift of 3 units up
