Answer:

Option 2 and 5 are correct. Look down for my explanation↓:

Step-by-step explanation:

So We need to tell which one of them is quadratic function.

Option 1 is exponential decay so, it is not quadratic.

Option 2 is quadratic because the diver will take the parabolic shape when jumps.

Option 3 is not quadratic. Option 4 is not quadratic it is linear.

Option 4 is again exponential not quadratic.

Option 5 is quadratic because it takes the parabolic shape again.

So I need help again so here is the question “My mom is baking cookies for a party. The recipe requires 2 eggs for every 4

seraphim [82]

Answer:

She has enough sugar.

Step-by-step explanation:

Let x = cups of sugar needed

eggs/cups of sugar = 2/4 = 1/2

12 eggs/x = 1/2

24 = x

Since she as 25 cups available and she needs 24 cups, it looks like she has enough sugar with 1 cup left over. I hope she is making chocolate chip cookies.

The ordered pairs in the table below represent a linear function.

Lilit [14]

Answer:

The slope is 2

Step-by-step explanation:

Given

x y

2 3

5 9

Required

Determine the slope

First, we have:

$(x_1,y_1) = (2,3)$

$(x_2,y_2) = (5,9)$

The slope is then calculated as:

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

This gives:

$m = \frac{9-3}{5-2}$

$m = \frac{6}{3}$

$m =2$

<em>Hence, the slope is 2.</em>

(Inequalities) what do you have to do when multiplying or dividing by a negative number?

Rashid [163]

Answer:

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative <u>YOU MUST FLIP THE INEQUALITY SIGN.</u>

Step-by-step explanation:

You are welcome.

And I hope this helps. :)
