Answer:
x=3.5
Step-by-step explanation:
add 2 to each side to cancel out the -2
6x=2x+14
subtract 2x from each side
4x=14
divide by 4
x=3.5
"<em>The product of 8 and a number increased by 4 is 60" </em>can be written as:
8y + 4 = 60
Your answer is A.
2.80 is more than 2, i would round it.
So sorry if this is wrong :(
Point-slope:
y-y1= m(x-x1)
Plug in what you know.
y1= 1 and x1= -8
y-1= 2/5(x-(-8)
y-1= 2/5(x+8)
Distribute.
y-1=.4x+ 3.2 <- that is the final answer
I hope this helps!
