Answer:
15
Step-by-step explanation:
Use the distributive property
4x+4=64, then subtract
4x=60, then divide
x=15
Answer: 2x for x=3: 2(3) = 6.
Step-by-step explanation:
Answer:
y= 3/2x + 24
Step-by-step explanation:
the slope of the line can be found with this formula: (y2-y1)/(x2-x1) where x and y are the coordinates of two points.
m = (9-6)/(-10+12) = 3/2
for find the equation or the line we can use this formula:
y-y1 = m(x-x1)
y-9 = 3/2(x+10)
y = 3/2x +15+9
y = 3/2x + 24
Answer:
see explanation
Step-by-step explanation:
let y = f(x) then rearrange making x the subject
y = 2x - 10 ( add 10 to both sides )
y + 10 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x
(x) = 
Answer:
y= x-1
