Answer:

A) x=4

B) x=35/2

Step-by-step explanation:

calculate the product

A) 5x/2+1=11

multiply both sides of the equation by 2

5x+2=22

move the constant to the right hand side and change its sign

5x+22-2

now subtract the numbers

5x=20

now didvide both sides

5x=20

x=4

calculate the product

2x/7-3=2

multiply both sides of the equation by 7

2x-21=14

move the constant to the right hand side and change its sign

2x=14+21

add the numbers

2x=35

now divide both sides of the equation by 2

x=35/2

What is the equation in slope intercept form of the line that contains the point (8, -2) and has a y-intercept of -4?

Alecsey [184]

Y=mx+b,slop intercept form
we need to find the slope.we nned to point
(-8,2) is given you can get the other by understanding the defintion of y-intercept (0,-4)
$m = slope = \frac{ 2 - ( - 4)}{ - 8 - 0} = \frac{6}{ - 8}$
m=-6/8,b=y-intercept=-4
$y = \frac{ - 6}{8} x + ( - 4)$
