Answer:
#12 is 1
Step-by-step explanation:
I feel it should be 30 because x represents the number of lessons, and 30 is multiplied by that.
Answer:
m<A=94
Step-by-step explanation:
(2x+10)+(2x+2)=180
4x+12=180
-12 -12
4x=168
/4 /4
x=42
m<A= 2x+10
m<A=2(42)+10
m<A=84+10
m<A=94
Check:
Add m<A and m<B which should equal 180.
m<B=2x+2
m<B=2(42)+2
m<B=84+2
m<B=86
94+86=180
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
30x+ 8 = 128
If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
First, plug in the given point into y=mx +b to find b (the y-intercept of the line). Use the same slope (m) in the equation since parallel lines have the same slope (3 in this case).
-1 = 3(4) +b
-1 = 12 + b Subtract 12 to both sides.
-13 = b
Now, put your m and b into y=mx+b.
The final answer/equation of your line is:
y=3x -13
