Let X = the number of yards he needs to mow.

Each yard he gets $25, so you would multiply 25 by x to find the total amount he makes.

Now you have 25x.


He needs at least $400 total.

At least means the amount can either equal 400 or be greater than 400.

This would make the inequality:

25X ≥ 400


Now to solve, divide both sides by 25:

25x ≥ 400 =

x ≥ 400 / 25

x ≥ 16


He needs to mow at least 16 yards.

Evaluate the expression for x = 4: 6+ (10 - x)2 - 20​
Liono4ka [1.6K]

6 + (10 - 4)2 - 20 = 6 + 12 - 20 = 18 - 20 = -2

Assuming that the two in the middle of the expression is multiplied by (10 - x) the answer would be -2. I apologize if I did not read your question right.

Nathaniel purchases a one-year membership pass to an art museum. As a member, he receives a discounted entrance fee. The total c
wolverine [178]

It's a linear function with y-intercept = 12.

The slope-intercept form:

f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5

We have the equation of a line:

\boxed{f(x)=1.5x+12}

We need calculate the value of function for x = 1 and x = 20.

Substitute:

f(1)=1.5(1)+12=13.5

f(20)=1.5(20)+12=30+12=42

$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

\$13.50-\$12.00=\$1.50

The total cost is $42.00 after 20 visits.
