Answer: Many solutions
Step-by-step explanation:
Let's solve for x.
3x−7y=−14−3x+6y
Step 1: Add 3x to both sides.
3x−7y+3x=−3x+6y−14+3x
6x−7y=6y−14
Step 2: Add 7y to both sides.
6x−7y+7y=6y−14+7y
6x=13y−14
Step 3: Divide both sides by 6.

Which of the following is a factor of x3 + 2x2 - 25x – 50?
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)

A bacteria population is going exponentially with a growth factor of 1/6 each hour. By what growth factor does the population change each half an hour select all that apply?
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
Quadrilateral ABCD is a parallelogram. If adjacent angles are congruent, which statement must be true?
Answer:
Step-by-step explanation:
A parallelogram is a shape that has two sets of parallel. There are a number of examples of parallelogram including but not limited to, square, rectangle, rhombus etc
From the question, the answer is, the shape is a rectangle. This is because the question says that the shape has its adjacent angles congruent, this means that they are supplementary(i.e they add up to 180). A rectangle is the one who fits the perfect description

AXYZ has side lengths in the ratio 3:4:5. Which group of three lengths represents a triangle similar to AXYZ?
Answer:
36, 48, 60
Step-by-step explanation:
if each side is 3, 4, and 5, then when you multiply each of these numbers by 12 then you get 36, 48, 60
3x12=36
4x12=48

The length of a rectangle 4 yd is longer than its width. If the perimeter of the rectangle is 68 yd, find its length and width.
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
t) The Perimeter of a change 84cm. If the enth is on find length the Width

x(6x+5)
these are the factors of a quadratic that opens up. The value will be less than zero between the roots.
the roots are:
x = 0
6x + 5 = 0
6x = -5
x = -5/6
x = {-5/6, 0}

Which of the following is a rational number but not an integer?
188, 13 2/5, -4, or -51
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:
13 2/5Step-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

Which graph does not represent a function?
On a coordinate plane, a curved crosses the y-axis 1 time and the x-axis 2 times.
On a coordinate plane, a straight line with a negative slope crosses the y-axis 1 time and the x-axis 1 time.
On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.
On a coordinate plane, a line with an s curve crosses the y-axis 1 time and the x-axis 1 time.
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.
What is a function?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.

find the value of the trig function indicated
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]

Henry is buying bagels for a family gathering. Each bagel costs $0.75. Answer the
questions below regarding the relationship between the total cost and the number of
bagels purchased.
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.
