HELP PLEASE!! The cost to fill a car's tank with gas and get a car wash is a linear function of the capacity of the tank. The co

sts of a fill-up and a car wash for three different customers are shown in the table. Write an equation for the function in slope-intercept form. Then, find the cost of a fill-up and a car wash for a customer with a truck whose tank size is 25 gallons.

The equation would be y=2.10x+3.25!


Also know as A lol


If you plug in 9 as x and add 3.25 it is an easy way to check the answers for further questions!


Have a good day! :-)


If it is not correct or doesn't look quite right or needs to show proof please comment!

Answer:

f(x)=2.1x+3.25

<h2>Cost for truck = $55.75.</h2>

Step-by-step explanation:

To right the linear equation in slope-intercept form, we first need to find the slop, which is defined

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Now, we choose to points from the table (9, 22.15) and (16, 36.85). Using this points, we calculate the slope.

m=\frac{36.85-22.15}{16-9}=\frac{14.7}{7}=2.1

Now, using one point and the slope, we find the point-slope form, which is gonna give us the slope-intercept form:

y-y_{1}=m(x-x_{1}))\\y-22.15=2.1(x-9)\\y=2.1x-18.9+22.15\\y=2.1x+3.25

Therefore, the right choice is the first one, because it's the only one that has this linear equation.

In addition, to find the cost for a car with 25 gallons of gas size, we just have to replace this number in the x-variable:

y=2.1(25)+3.25=55.75

Therefore, the cost for a truck with a tank size of 25 gallons, is $55.75.

My daughter needs help and I don't understand the question ethier.
WINSTONCH [101]

So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be (1.07*2+0.85*2+2.12*2)

Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is 7(1.07*2+0.85*2+2.12*2) . Now we can solve it from there.

Firstly, solve the multiplication inside the parentheses: 7(2.14+1.7+4.24)

Now add up what's inside the parentheses: 7(8.08)

Lastly, multiply and <u>your answer will be $56.56</u>

erastovalidia [21]

Answer:

8 - 2i

Step-by-step explanation:

Just add the real parts together and then add the imaginary parts together

5 + 3 = 8

-4i + 2i = -2i

8 - 2i
