Possible Answer

Let d be the common difference. Then, y = x + d, z = x + 2d, and w = x + 3d. Substitute these values into the expression x + w - y and simplify. x + (x + 3d) - (x + d) = x + 2d or z.

It would be 29 because of the c and the w y equal to z

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three op
lutik1710 [3]

The statement that is true about the quadratic function is (b) the graph of the function is a parabola.

<h3>How to determine the true statements?</h3>

The quadratic function is given as

f(x) = x2 – 5x + 12

Rewrite as

f(x) = x² – 5x + 12

All quadratic functions are parabola

This means that option (b) is true

Set x = -10 to calculate f(-10)

So, we have

f(-10) = (-10)² – 5(-10) + 12

Evaluate

f(-10) = 162

This means that option (a) is false

Set x = 20 to calculate f(20)

So, we have

f(20) = (20)² – 5(20) + 12

Evaluate

f(20) = 312

This means that option (d) is false

Set x = 0 to calculate f(0)

So, we have

f(0) = (0)² – 5(2) + 12

Evaluate

f(0) = 12

This means that option (e) is false

The leading coefficient in f(x) = x² – 5x + 12 is positive

Graphs with positive leading coefficient opens up

This means that option (c) is false

Hence, the true statement about the quadratic function is (b)

Jim needs to mix a medication with water to make the appropriate solution. The medications says to mix 3 oz of medication with 5
skelet666 [1.2K]

Answer:

38 or 38.33 cups of water.

Step-by-step explanation:

You need 5 cups of water for every 3 ounces of medication. We can set up a proportion: #oz of medication/#cups of water= #oz of medication/# cups of water. We can plug in some numbers from the problem.

3/5=23/n. You can use any variable, but I'm using n for how many cups of water Jim will need for 23 ounces of medication.

We can cross multiply: 3*n=5*23.

3n=115

We divide both sides by 3.

n=38.3333333.......

Rounding to the nearest whole number, Jim will need 38 cups of water, or 38.33 cups if you're rounding to the nearest hundredth.

Hope this helps :)
