Step-by-step explanation:

It is true!

Let's say we subtract 6 from both sides

-2x -6< 0                       Now Let's add 2x to both sides

-2x + 2x - 6 < 0 + 2x

- 6 < 2x                         We did so we would be dividing by a number greater than 0.                         Divide by + 2

-6/2 < 2x / 2

-3 < x                            Notice you still get the open end of the inequality sign closest to the x without changing the direction of the inequality.

Answer:

(x - 5)(x + 2)(x + 5)

Step-by-step explanation:

x³ + 2x² - 25x - 50

x³ + 7x² - 5x² - 35x + 10x - 50

x(x² + 7x + 10) - 5(x² + 7x + 10)

(x - 5)(x² + 7x + 10)

(x - 5)(x² + 2x + 5x + 10)

(x - 5)(x(x + 2) + 5(x + 2))

(x - 5)(x + 2)(x + 5)

Answer:

The bacteria population will change with a growth factor of 1/12 for every half an hour or 1/12 per 30 minutes. (I don't know what the options are, but anything related to the answer I gave should be right.)

Step-by-step explanation:

Simple mathematics should get you the right answer. Here we are dealing with a fraction in a fraction. The first scenario should look like this: 1/6 / 1. Basically, that looks like one-sixth over one. Obviously, if we divide 1/6 by 1, we would get 1/6 itself again and we want to know what growth factor the population changes by for every half an hour. There are 30 minutes in half an hour and 60 minutes in one hour. Let's use the simplified terms to our advantage. Now, our first scenario should look like this: 1/6 / 60. Looks better now doesn't it? (Check the linked image to see the full scenario and how I did it in this next part.) For me, I divided 60 by 30 to get the scale factor, which is 2, then I divide 2 by 1/6 to get 1/12. Finally, we have 1/12 per half an hour! If I am wrong, please let me know and I hope this helps! :D

w + 4

------------------------

l l

l l w

l l

------------------------

Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w

Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds

1.Simplify/combine like terms:

w + 4 + w + w + 4 + w =

4w + 8 =

Now it's a 2-step algebra equation

4w + 8 = 60

2.Subtract 8 on both sides

4w = 56

3.Divide both sides by 4

w = 14

Answer:

c

Step-by-step explanation:

Answer:

[tex]\cos(\theta)=\frac{4}{5}[/tex]

Step-by-step explanation:

Step 1:

Let us find the missing side. We know this is a right triangle, so we can use the pythagorean thereom to find the last side. Let us set 12 as variable a, 20 as variable c, and the unknown side as variable b.

[tex]a^2+b^2=c^2\\12^2_b^2=20^2\\b^2=400-144\\b^2=256\\b=\pm16[/tex]

We do know that a length can never be negative, so the side b would be 16.

Step 2:

According to SOHCAHTOA, cosine is utilizes the adjacent and hypotenuse of the given angle theta. Let us write the equation:

[tex]\cos(\theta)=\frac{adjacent}{hypotenuse} \\\\\cos(\theta)=\frac{16}{20} \\\\\cos(\theta)=\frac{4}{5}[/tex]

I hope this helps! Let me know if you have any questions :)

Answer:

On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.

Step-by-step explanation:

Vertical line test.

If you draw a vertical line, parallel to the y-axis and it crosses a line or shape twice, it is not a function.

On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

On taking the vertical line test it is observed that If you draw a vertical line, parallel to the y-axis and it crosses a line or shapes twice, it is not a function.

Therefore, on a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.

Answer:

Option C

Step-by-step explanation:

Rational numbers are numbers of the form p/q, where p and q are integers and q not equal to zero.

Integers are number of the form p/q , where q = 1

Option A : 188 => integer and rational

Option  B: 13   =>  integer and rational

Option C :2/5  =>  rational but not integer ( because q = 5 and not 1 )

Option D : - 51 => integer and rational

Answer:

Step-by-step explanation:

As,

Integers includes whole numbers, and negative of the whole numbers.

And Rationals includes every fraction, Integers and negative fraction.

So,

188, -4, and 51 are both Integers and Rationals.

But,

Only 13 2/5 is a mixed fraction included only in rationals and not in Integers

Answer:

0.75x=(total cost)

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is A(x) =0.75x .

So A(12) = 9, meaning 12 bagels will cost 9 dollars.
