A, 4x= -28

netineya [11]2 years ago

Answer:

A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3

Step-by-step explanation:

A. 4x= -28

Divide both sides by 4.

\frac{4x}{4\\}=\frac{-28}{4}. x= -7

B. x- -6= -2 ->  x+6= -2

Subtraction 6 to both sides.

x- +6-6= -2-6,  x= -8

C. -x+= -9 -> x= 9

D. -3x+7=1

Subtraction 7 to both sides.

-3x+7-7 =1-7 , -3x=-6

Divide both sides by -3.

\frac{-3x}{-3} = \frac{-6}{-3}, x= 2

E. 25x+-11= -86 -> 25x-11= -86

Add 11 to both sides.

25x-11+11= -86+11, 25x= -75

Divide both sides by 25.

\frac{25x}{25} = \frac{-75}{25}, x= -3

2. 2x+9= -15

Subtraction 9 to both sides.

2x+9-9= -15-9,  2x= -24

Divide both sides by 2.

\frac{2x}{2} = \frac{24}{2} ,  x= 12

I don't think there's an answer.

I hope it helps you!

How do you solve -36x+2/4 (the “/“ is because it’s a fraction)
butalik [34]

you cannot solve this because it is an expression.  you need an equals to make it an equation.

-36x + 2/4 is an expression which can be simplified

-36x+1/2

1. Which of the following coordinates for p will make line mn perpendicular to line op in the diagram below?
TiliK225 [7]
1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.

2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5

y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1
