Answer:
(0, 1 )
Step-by-step explanation:
To find the y- intercept, that is where the function crosses the y- axis.
At this point the x- coordinate is zero.
Substitute x = 0 into the function, that is
f(0) = 
= 1 ← y - intercept
Answer:
k/11 =7
Step-by-step explanation:
k divided by 11 is 7
k/11 =7
Multiply each side by 11
k/11*11 = 7*11
k = 77
Answer:
27
Step-by-step explanation:
Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour
