Answer:

C=75t+100

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

C=mt+b

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

b=\$100 ----> set fee

we have the ordered pair (2,250)

substitute the given values

250=m(2)+100

Solve for m

2m=250-100

2m=150

m=\$75\ per\ hour

The linear function is equal to

C=75t+100

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.
Rasek [7]

Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x - \frac{3}{4}) + \frac{5}{4} = -7

subtract \frac{5}{4} on each side of the equation


x - \frac{3}{4} = -8.25

add \frac{3}{4} on each side of the equation

x = -7.5


-7.5 - 3/4 = -8.25

-8.25 + 5/4 = <u>-7</u>


So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.


There you go! I really hope this helped, if there's anything just let me know! :)

Problem in the attachment
TEA [102]
You can solve this by multiplying each numerator by the answer choices and trying to divide them. I can't get the fraction maker to work at the moment, so I'll write the calculations on a separate attachment.

As you can see, the only choice that works to eliminate both fractions is the fourth choice, 50x.
