The answer is 2. because you need to do what’s in the parentheses first. so for the top, (17-12=5) then -8 x 5 = -40. so that’s the top. bottom, 8 - (-2) when you subtract a negative it becomes positive. so that is 10. now it’s -2 x 10. and final answer is -40/-20= 2. hope that helped

HERE ARE TWO NUMBER MACHINES A AND B
nika2105 [10]

Answer:

x=-7

Step-by-step explanation:

We can write them both like functions like this

A=5x-4

B=3x+8

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

A=3B

we replace with the functions

5x-4=3(3x+8)

we solve for x

5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7

The output that makes the out put of A 3 times teh output of B is -7

The midpoint of RS is M(1, 2). One endpoint is R(-6, 6). Find the coordinates of endpoint S.
AysviL [449]

Answer:

The coordinates of point S are (8,-2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

Let

Point S(x2,y2)

substitute the given values

(1,2)=(\frac{-6+x2}{2},\frac{6+y2}{2})

<em>Solve for x2</em>

1=(-6+x2)/2\\2=-6+x2\\x2=2+6=8

<em>Solve for y2</em>

2=(6+y2)/2\\4=6+y2\\y2=4-6=-2

therefore

The coordinates of point S are (8,-2)
