You are given a cell phone bill. You are charged $52 for the month. There is a $40 monthly fee and you are charged $4 per megab

The equation for the problem is y = 4x + 40. The slope is 4 and the y intercept is 40

The standard equation for a linear equation is given by:

y = mx + b

Where m is the slope of the equation, b is the y intercept, y is a dependent variable and x is the independent variable.

Let x represent the charge per megabyte used and let y represent the total charge for the month

since there is a $40 monthly fee and you are charged $4 per megabyte of data used, hence:

y = 4x + 40

Comparing with the standard linear equation:

The y intercept is 40, this means that even if no data is used, $40 must be paid.

The slope is 4, that is for every megabyte used, $4 is paid.

The amount to pay for 10 MB is:

y = 4(10) + 40 = $80

$80 is paid to use 10 megabytes

Which graph shows the solution

kodGreya [7K]

The given inequality is:

-5c + 2 ≤ 27

Subtracting 2 from both sides, we get:

-5c + 2 - 2 ≤ 27 - 2
-5x ≤ 25

Dividing by 5 on both sides we get:

- x ≤ 5

Multiplying by -1 we get:

x ≥ 5

Remember that multiplying or dividing by a negative number changes the direction of inequality symbol.

From the given options, the second graph correctly represents this solution.

Answer:

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a^2 + 9^2 = 15^2

a^2 +81 =225

Subtract 81 from each side

a^2 = 225-81
