9
Step-by-step explanation:
15x+12=19x-24
15x-19x=-24-12
-4x=-36/÷(-4)
x=9
You first put all the x on one side and numbers on the other and be careful about + and - and then you divide by everything with the x so you have only the x left and you get the aswer.
Answer:
$0.06 per dollar should be right
M = 7 is the given slope
(x,y) = (-4,-3) is the given point
Turn to slope-intercept form and use these values to find b
y = mx+b
-3 = 7(-4)+b ... plug in the given values
-3 = -28+b
-3+28 = -28+b+28
25 = b
b = 25
since we know that m = 7 and b = 25, the equation y = mx+b turns into y = 7x+25
The final answer is choice A
