swat32

Answer:

Second option: $2x=90$

Step-by-step explanation:

Let be "x" the number of candy bars Brady sold on Saturday.

For this exercise you need to analize the information provided in the exercise.

According to the information provided, Brady gets paid $2 for every candy bar he sells. This can be expressed as:

$2x$

You know that Brady made a total of $90 on Saturday; this mean the product of $2x$ is 90.

Based on this, you can write the following equation that represents the number of candy bars Brady sold on Saturday:

$2x=90$

Observe that this matches with the second option.

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)
