DIA [1.3K]

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

I need to know dis answer

Answer:

<em>(-8,4)</em>

Step-by-step explanation:

<u>System of Equations:</u>

Solve the following system of equations by the substitution method:

5x - 6y = -64      [1]

y = 20 + 2x        [2]

Substituting y from [2] in [1]:

5x - 6(20 + 2x) = -64

Operating:

5x - 120 - 12x = -64

Simplifying:

-7x - 120 = -64

Adding 120:

-7x = -64 + 120 = 56

x = 56/(-7) = -8

x = -8

From [2]:

y = 20 + 2(-8) = 4

Solution (-8,4)
