1. 9c-3c=48A) c=9B) c=3C) c=4D) C=8

Alona [7]

$9c\text{ - 3c = 48}$

To solve this equation, we need to subtract both, 9c - 3c:

$9c\text{ - 3c = 6c = 48}$

Dividing by 6 at both sides of the equation

$\frac{6c}{c}\text{ = }\frac{48}{6}$

Then

$c\text{ = 8}$

Then the answer C = 8. (Option D)

Determine the standard form of the equation of the line that passes through (-8, -6) and (-4, 9)

Darya [45]

Answer:

15/4 x-y=-24

Step-by-step explanation:

the standard form is ax+by=c

two points (x1,x2) , (y2,y1)

x1=-8 x2=-6

y1=-4 y2=9

find slope m: y2-y1/x2-x1

m=9-(-6)/-4-(-8)

m=15/4

find b: take any point(-8,-6)

y=mx+b

-6=15/4 (-8)+b

-6=-30+b

b=-6+30

b=24

y=15/4 x+24

standard form: y-15/4x=24

OR : 15/4 x-y=-24
