Answer:

D. $128.80

Step-by-step explanation:

You find tip by dividing the percentage by 100 and multiply that number by the decimal. ($112)*(.15)= $16.80

Then you add them and get $128.80

HELP ME HELP ME please !!! 10 points

Answer:

The slope is $\frac{3}{2}$

The y-intercept is 9

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

m is the slope of the line whose rule is $m=\frac{y2-y1}{x2-x1}$

b is the y-intercept, you can find it by substituting x, y in the equation by (x1, y1) OR (x2, y2)

Let us solve the question:

Choose any two-point from the table

∵ The line passes through the points (2, 12) and (4, 15)

∴ x1 = 2 and x2 = 4

∴ y1 = 12 and y2 = 15

→ Use the rule of m to find it

∵ $m=\frac{15-12}{4-2}=\frac{3}{2}$

∴ m = $\frac{3}{2}$

∴ The slope is $\frac{3}{2}$

→ Substitute its value in the form of the equation above

∴ y = $\frac{3}{2}$ x + b

→ To find b substitute x and y by x1 and y1

∴ 12 = $\frac{3}{2}$ (2) + b

∴ 12 = 3 + b

→ Subtract 3 from both sides

∴ 12 -3 = 3 - 3 + b

∴ 9 = b

∴ The y-intercept is 9

Evaluate the expression when m = 63 and n = 45

sesenic [268]

The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.

<h3>What is an expression?</h3>

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

<u>Given the following variables:</u>

m = 63.

n = 45.

Substituting the given variables into the given expression, we have;

Expression = (3m - n)² + 4m.

Expression = (3(63) - 45)² + 4(45).

Expression = (189 - 45)² + 180

Expression = 144² + 180

Expression = 20,736 + 180

Expression = 20,916.

Divide 40x/64y by 5x/8y.

Lemur [1.5K]

<u>Answer:</u>

The correct answer option is C. 1.

<u>Step-by-step explanation:</u>

We are to divide $\frac { 4 0 x } { 6 4 y }$ by $\frac { 5 x } { 8 y }$ .

Rewriting them as a fraction in whole:

$\frac { \frac { 4 0 x } { 6 4 y } } {\frac { 5 x } { 8 y } }$

Changing the division into multiplication by taking the reciprocal of the fraction in the denominator to get:

$\frac { 4 0 x } { 6 4 y }$ × $\frac{8y}{5x}$

Cancelling out the like terms to get:
