Answer:
First answer option:
"The first equation should be multiplied by 2 and the second equation by 3. "
Step-by-step explanation:
The first equation should be multiplied by 2 and the second equation by 3. This way the term in y in the first equation becomes "(2) (-3y) = -6y", and the term in y in the second equation becomes "(3) (2y) = 6y" so when added term by term, the term in "y" disappears.
That is represented by the first statement in your list of possible answers
3.) Alex makes $31,992 per year and pays about 15% of his gross monthly income in federal
taxes. He wants to find an apartment to rent. Estimate how much he can afford to pay for
rent each month. Then determine how much money he will have after taxes and rent are
paid.
Answer: 1699.5 dollars
Step-by-step explanation:
If Alex makes $31,992 per year, then his monthly income will be
31992/12 = 2666 dollars
and he pays about 15% of his gross monthly income. That is
15/100 × 2666 = 399.9
The remaining money will be
2666 - 399.9 = 2266.1
He should able to afford 25% of his monthly income for rent
25/100 × 2266.1 = 567 dollars
The money left after tax and payment for rent will be
2266.1 - 567 = 1699.5 dollars

in the following triangle theta=60.Find the values of the angles of the angles B and B'
Answer:
180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show 60,60,60 if equilateral
For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.
Vectors 60 if right angled triangle = 90-60 = 30
So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.
Step-by-step explanation:
Statement: If two vectors are represented by the sides of a triangle both in magnitude and direction taken in order, the resultant sum of the vectors is given by the closing third side of the triangle taken in the reverse order both in the magnitude and direction

Ariel is working at a meat- packing plant 5 nights a week. Her regular wage is $11 an hour. She earns time and a half for any overtime hours. This week she worked 9 hours of overtime. How much will Ariel earn for overtime this week?
Answer:
She will earn $148.50 in overtime this week.
Step-by-step explanation:
First, you multiply 11 by 1.5. That gets you 16.5. So, for every overtime hour she works, she gets $16.50. Since she works 9 overtime hours, you multiply 16.5 by 9 to 148.5. So, she earns $148.50 for overtime this week.

Use the graph to estimate x when y = 0.
You can use this table too. (y = 4x - 5)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
You could just use the equation to get an answer
Substitute y in as 0
0 = 4x - 5
+ 5 to both sides
4x = 5
Divide both sides by 4:
x = 5/4 or 1.25
HOWEVER, you were supposed to use the graph.
If you look at where the line meets the x axis, you can see it is around 1.2

A circle has an area of approximately 615 square millimeters. What is the diameter of the circle

D

28
SUBMIT ANSWER
Answer:
When using the given information, the diameter of the circle is going to be 28 mL.
Step-by-step explanation:
First, we need to know the formula for finding the area of a circle.
[tex]Area=r^2\pi[/tex]
Now, we need to rearrange the formula so we can find the radius.
[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]
Next, we plug in the given area into the equation.
[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]
[tex]Radius=\sqrt{196}[/tex]
[tex]Radius=14[/tex]
Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.
[tex]14 * 2=28[/tex]
So, the diameter of the circle is 28 mL

The length of a rectangular park is four timesfour times its width. The park is surrounded by a 33-foot-wide path. Let x denote the width of the park. Write a quadratic function to represent the total area of the park and the path.
The quadratic function that represents the total area of the park and the path is _____.
(Simplify your answer. Do not factor.)
Answer:
A(x) = 4x^2 + 330x + 4356
Step-by-step explanation:
width of park: x
length of park: 4x
width + path width = x + 66
length + path width = 4x + 66
area = (x + 66)(4x + 66)
area = 4x^2 + 66x + 264x + 4356
area = 4x^2 + 330x + 4356
A(x) = 4x^2 + 330x + 4356
Sullivan and Carter both went trick or treating in the neighborhood, and now they're
comparing their candy haul. If Sullivan got s number of pieces and Carter got 2s,
what does that tell you about the relationship between the amount of candy they
each had?
Answer:
Step-by-step explanation:
Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.
What is amount?" Amount is defined as the representation of total quantity of given object."
According to the question,
Number of candies Sullivan got = s
Number of candies Carter got = 2s
Compare the given amount of data we get,
Number of candies Carter got = 2(Number of candies Sullivan got )
This shows Carter got twice number of candies comparison to Sullivan.
or
Number of candies Sullivan got = [tex]\frac{1}{2}[/tex] (Number of candies Carter got)
Sullivan got half number of candies compare to Carter.
Hence, we conclude Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.

B, C and F
Step-by-step explanation:
Given
f(x) = [tex]\frac{7}{2x(x+3)(x-9)}[/tex]
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

We can't state that because we don't know if ∠NPK is 90º
Triangle KPN is similar to triangle KQN
It is the same case as the alternative a, we can't say the triangles are similar because we don't the angles for KPN. We know that LN is perpendicular to NP, but we don't if NP is perpendicular to PK, ∠NPK might be 89,9º, that is almost 90º.
KP = 0.5 LN
Once the four sides of the square are equal, LQ = QN. But from the picture we can only state that KP length is approximately the length of NQ (or 0.5 LN)

B)

C)

D)

Answer:
1) B
2) A
Step-by-step explanation:
1) When a triangle is similar it means that all the angle measures are the same.
So for triangle UVT the angle measures are:
U=29.95, V=56.25, T=93.82
For triangle RSQ the angle measures are:
R=29.95, S=56.25, Q=93.82
So the answer is that they are similar (triangle UTV ~triangle RQS)
2) For this problem each sided is proportional because of the parallel lines. (It's been a while since I've done this kind of math but I'll give it a go)
