Answer:

(b) and (c) are true

Step-by-step explanation:

Given

Function A and B

First, calculate the slope of A

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{24 - -21}{8- -7}

m = \frac{45}{15}

m  =3

The equation of function A is:

y = m(x - x_1) + y_1

y = 3(x - 8) + 24

y = 3x - 24 + 24

y = 3x

The general form of a function is:

y = mx + b

Where m = slope and b = y\ intercept.

This implies that:

Slope = 3

Y\ intercept = 0

For function B:

y = 4x - 3

Slope = 4

Y\ intercept = -3

By comparison:

(b) and (c) are true

olga55 [171]
Hello!

For every 1 blue marble there are 5 greens

You add the numbers in the ratio

1 + 5 = 6

Divide this number from the amount of marbles

60 / 6 = 10

Multiply the ratio by this

1 * 10 = 10

5 * 10 = 50

There are 10 blue marbles and 50 green ones

The answer is 10

Hope this helps!
