Answer:
5x
Step-by-step explanation:
4(2x+3)-3(x+4)
4(2x) + 4(3) - 3(x) - 3(4)
8x + 12 - 3x - 12
8x - 3x + 12 - 12
5x
Answer:
HUH
Step-by-step explanation:
Answer:
3y+4x=5
Step-by-step explanation:
step 1
Find the slope
we have
(–7, 11) and (8, –9)
m=(-9-11)/(8+7)
m=-20/15
m=-4/3
step 2
Find the equation of the line into point slope form
we have
m=-4/3
point (-7,11)
substitute
y-11=-(4/3)(x+7) ----> equation of the line into point slope form
Multiply by 3 both sides
3y-33=-4(x+7)
3y-33=-4x-28
3y+4x=33-28
3y+4x=5 -----> equation of the line into standard form
