Answer:

x = ± $\sqrt{\frac{f}{m} }$

Step-by-step explanation:

Given

mx² = f ( isolate x² by dividing both sides by m )

x² = $\frac{f}{m}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{f}{m} }$

13. Mis the midpoint of PR, PM = 2x + 5, and MR = 4x – 7. Solve for x and find PR.

enyata [817]

Add 2x + 5 and 4x - 7

Then you isolate the variable or “get rid of” the numbers that re stopping you from getting “x”.

By doing the inverse operation.

If you add ___ you subtract ____ it form itself

If you subtract ___ you add ____ To itself.

So you Cancel out by getting rid of the other numbers.

Answer:

<h2>See below</h2>

Step-by-step explanation:

I can't drag and drop the graphs, but I can graph the equations shown. Then, all you will have to do is match the graphs shown the the graph that I will provide.

<h3>EQUATION 1: y = x² - 2</h3>

Graph Properties:

Opens up

Vertex is 0, -2

Axis of symmetry is x = 0

Graph photo shown in file called equation 1 graph

<h3>EQUATION 2: y = 2x²</h3>

Graph Properties:

Opens up

Vertex is 0, 0

Axis of symmetry is x = 0

Graph photo shown in file called equation 2 graph

<h3>EQUATION 3: y = (x - 2)²</h3>

Graph Properties:

Opens up

Vertex is 2, 0

Axis of symmetry is x = 2

Graph photo shown in file called equation 3 graph

I'm always happy to help :)

Liam makes soap sculptures of sea turtles. Each sculpture weighs 3\8 pounds he ships them in a wooden box that weighs 2 pounds t

wlad13 [49]

Answer:

8 turtles

Step-by-step explanation:

Each of Liam's sea turtle sculpture weighs 3\8 pounds and he ships them in a wooden box that weighs 2 pounds.

The weight of the box filled with the sea turtles is 5 pounds.

This means that the weight of the sea turtles in the wooden box is:

5 - 2 = 3 pounds

To find the number of sea turtles in the box, we simply divide the total weight of the turtles in the box by the weight of each turtle. That is:

$\frac{3}{\frac{3}{8} }$ = 8 turtles

There are 8 turtles in the box.
