Which pairs of points would result in a line with a rate of change of 2:1? select all that apply
Reil [10]

Answer:

A,C,D

Step-by-step explanation:

Complete Question:

<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>

<em>A.(−4,−11) and (−2−7) </em>

<em>B.(5,6) and (−5, 12) </em>

<em>C.(0,−3)and (−4,−11) </em>

<em>D. (0,−3) and (5, 7)</em>

<em />

Rate of change is the slope. 2:1 would mean a slope of simply, 2.

We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:

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

Where m is the slope and

x_1 is first x point

x_2 is second x point

y_1 is first y point

y_2 is second y point

Let's calculate slope of each of the choices.

A.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-7+11}{-2+4}\\m=2

THis one is okay.

B.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{12-6}{-5-5}\\m=-\frac{3}{5}

THis one is not 2:1.

C.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-11+3}{-4-0}\\m=2

THis one is okay.

D.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{7+3}{5-0}\\m=2

This one is okay.

Hence, A, C, and D all have rate of change of 2:1

Brand X costs $1.65 for 11 ounces. Brand Y costs 2 cents more per ounce. What is the cost of 15 ounces of brand Y?
34kurt

Answer:

$2.25

Step-by-step explanation:

You can find the answer by setting up a simple equation.

Brand X is 1.65 for 11 ounces

we can find the cost of one ounce of Brand X by using division

1.65/11

.15

this means that for every ounce of Brand X, it costs 15 cents

Since brand Y costs two cents more per ounce that would make it be 17 cents per ounce

now all you need to do is multiply and solve.

.15 * 15 = $2.25

One of the roots of the equation x2−5x+q=0 is 2. Find the other root and the value of the coefficient q.
pishuonlain [190]

Answer:

q=6

Step-by-step explanation:

A root can be plugged in for X, so 2(2)-5(2)+q=0. This means -6+q=0. We can now even them out and know q=6
