Answer:

Step-by-step explanation:
Let
C(t) ---->the total cost of the electrician's services in dollars
t ---> the number of hours
we know that
The linear function in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
the y-intercept is equal to
----> set fee
we have the ordered pair (2,250)
substitute the given values

Solve for m



The linear function is equal to

Answer:
y = 7
Step-by-step explanation:
Solve for y:
7/y = 1
Take the reciprocal of both sides:
y/7 = 1
Multiply both sides by 7:
Answer: y = 7
1/2 of 8 is 4 so there would be 4/8 motorcycles + 1/8 cars would be 5/8 and the remainder is 3/8 so 3/8 is not cars or motorcycles
What is B? We cannot help you if we do not know what B is.
Answer:
1. BC = 18
2. m<ABC = 80°
3. x = 5
Step-by-step explanation:
1. If DE = 9, therefore:
(based on the midsegment theorem, DE is half the length of the third side, BC)
2. m<ADE = 80°, then,
m<ABC = 80°
This is because m<ADC and m<ABC are corresponding angles. Corresponding angles are congruent.
3. DE = 2x + 7 , and BC = 7x - 1, find BC
Thus:
(midsegment theorem)
(substitution)
Solve for x
Collect like terms
Divide both sides by 3
x = 5
