Answer:
7
Step-by-step explanation:
The initial value is another name for the y-intercept. This equation is written in point slope form (y=mx+b). And before you think y-intercept means y, right? No that is incorrect, I got that wrong in the beginning too ;)
y=mx+b
y=8x+7
b in the point slope form equation is always the initial value or y-intercept or whatever people call it. So what substitutes b out here? 7. So 7 is the initial value!
:) Hope you understand now! Have a good day!
The first blank is 121 and the second blank is 144
Answer:
<em>Mechanic A worked for 5 hours</em> and <em>Mechanic B worked for 15 hours</em>
I hope my answer and explanation helped!
<u>okay to get started you need to make a system of equations:</u>
x= number of hours worked by mechanic A
y= number of hours worked by mechanic B
x + y= 20
95x + 60y= 1375
<u>substitute in an equation:</u>
x + y= 20
y= 20- x
95x + 60(20-x)=1375
<u>Solve for x</u>
95x + 1200 - 60x=1375
35x =175
x= 5
<u>plug in x to solve for y</u>
x + y= 20
5 + y= 20
y=15
<u>Check work</u>
then you're done :D
