= 74 + 16 + 35 + 45

= 70 + 4 + 10 + 6 + 30 + 5 + 40 + 5

= 70 + 10 + 4 + 6 + 30 + 40 + 5 + 5

= 80 + 10 + 70 + 10

= 80 + 10 + 10 + 70

= 100 + 70

= 170

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723

What is the rate of change

Serggg [28]

Answer:

Slope = 0

Step-by-step explanation:

Let's use the equation $\frac{y2 - y1}{x2 - x1}$ for this problem.

We have two points: (2,0) and (-2, 0)

Let's plug them both into the equation shown above.

$\frac{0 - 0}{-2 - 2}$

Solve.

0 - 0 = 0

-2 - 2 = -4

$\frac{0}{-4}$ = $-\frac{0}{4}$ = 0

A zero in the numerator means this equation has a slope of 0.

Any line with a slope of 0 is a horizontal line.

Slope (rate of change) = 0
