i hope it can help u a bit

The other two special factoring formulas you'll need to memorize are very similar to one another; they're the formulas for factoring the sums and the differences of cubes. Here are the two formulas:

Factoring a Sum of Cubes:

a3 + b3 = (a + b)(a2 – ab + b2)

Factoring a Difference of Cubes:

a3 – b3 = (a – b)(a2 + ab + b2)

A triangle can have sides of 12, 19, and 30.
True or false

Answers

Answer:

True

Step-by-step explanation:

According to the Triangle Inequality, the sum of any two sides of a triangle has to be greater than the third side. 12+19 = 31 which is more than 30 so a triangle can have sides of 12, 19 and 30.

Find the value of x.


Answers

Answer:

x = 19

Step-by-step explanation:

The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.

3x + 5 + 7x - 15 = 180

~Combine like terms

10x - 10 = 180

~Add 10 to both sides

10x = 190

~Divide 10 to both sides

x = 19

Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position changes in feet per minute?

Answers

Answer:

6 ft/min

Step-by-step explanation:

Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)

Therefore,

the rate of feet per minute will be the feet divided by the minutes;

18 feet in 3 minutes = 18/3 ft/min

Therefore the rate is 6 feet per minute.

IF you need an explanation on what average rate implies:

Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.

r + 8 - 5r = 2(4 - 2r) solve for r please

Answers

-4r + 8 = 8 - 4r

0 = 0 so it's like {}

Answer:

r = 0

Step-by-step explanation:

This is actually the first time I've actually had a equation with the variable equaling 0.

so first things first you have the equation:

r + 8 - 5r = 2(4 - 2r)

so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:

r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:

8+ (-4r)= 8 -4r

you then add -4r to both sides to get this equation:

8+ ( -4r)= 8 -4r

    + 4r       +4r

8 = 8 + r

you then subtract 8 from both sides to get r:

8 = 8 + r

-8  -8

0 = r

to check substitute the 0 into r in the equation:

r + 8 - 5r = 2(4 - 2r)

0 + 8 - (5*0) = 2(4- (2*0))

8 = 8

Tada!!!

Find an equation for the line below.
Help me please :(

Answers

Answer:

y=3/2x+5/2

Step-by-step explanation:

I used the Y2-Y1/X2-X1

In this equation you can see that there are 2 points (-5,-5) and (1,4)

If you substitute, you will get

4+5/1+5

9/6 and if you simplify this, you will get 3/2

Now that we have the slope, we just have to use y=mx+b

(I'm using the point (1,4))  4=3/2(1)+b

                                         4=3/2+b

                                         5/2=b

Write an equation for a line that passes through (3, -4) & has a slope of -3.

Answers

Answer:

The answer is

[tex] \huge y = - 3x + 5[/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have

[tex]y + 4 = - 3(x - 3) \\ y + 4 = - 3x + 9 \\ y = - 3x + 9 - 4[/tex]

We have the final answer as

[tex]y = - 3x + 5[/tex]
