The cost of having a plumber spend h hr at your house if the plumber charges $30 for coming to the house and $x per hour for labor. the expression for the cost of the plumber coming to the house is how many dollars.

Step-by-step explanation:

Let

C-----> the cost of having a plumber spend h hours at your house

h----> the number of hours

x----> the cost per hour of labor

we know that

The linear equation that represent the cost C is equal to

In this linear equation in the slope-intercept form (y=mx+b)

the slope is equal to

the y-intercept b is equal to ---> charge for coming to the house

.6 is 1/2 of 12

the answer is actually d. i just took the test

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
