Answer:
for 4x = 20 you have to use the division property of equality divide 20 by 4
for x - 11 = 9 you have to use the addition property of equality add 9 to 11
for 5x + 6x = 22 you have to combine like terms add 5x and 6x to make 11x
for 5(x – 2) = 30 you have to use the distributive property multiply 5 and x; 5 and -2
4x = 20; x = 5
x - 11 = 9; x = 20
5x + 6x = 22; 11x = 22; x = 2
5(x – 2) = 30; 5x - 10 = 30; x = 8

Which must be true? Select two options. Point H is the center of the circle that passes through points D, E, and F.
Point H is the center of the circle that passes through points L, M, and N.
Line segment H E is-congruent-to line segment H D
Line segment L H is-congruent-to line segment N H
Line segment F L is-congruent-to line segment F N
Answer:
A. Point H is the center of the circle that passes through points D, E, and F.
C. Line segment H E is-congruent-to line segment H D
Step-by-step explanation:
The center of a circle is a point within it that has the same distance to all other points on its circumference.
Constructing a circle with center H would pass through the points D, E and F at the three vertices of the given triangle. Thus producing a circumscribed circle to the triangle. A circumscribed circle is one that can is constructed outside a given figure.
It can also be observed that, DH ≅ EH ≅ FH. So that, the line segment HE is congruent to line segment HD.
The correct options in the given question are: A and C.
Answer:
A. Point H is the center of the circle that passes through points D, E, and F
C. HC≈HD

Step-by-step explanation:
Larry is 8 years older than his sister. Two times Larry's age is five more
than three times his sister's age. How old is Larry now?
Answer:
larry is 19
Step-by-step explanation:
ok, so larry's age is y, his sisters age is x
x + 8 = y
thats the equation for him being 8 years older
now 2y = 3x + 5
his sisters age is 3x + 5 to get larry's age when its doubled
substitute x + 8 in for y
2 (x+8) = 3x + 5
2x + 16 = 3x + 5
16 = x + 5
x = 11
11 + 8 = y
y = 19
identify the domain and range of the function input 1,3,5,7 output 8,7,6,5
Answer:
Domain = 1,3,5,7
Range = 8,7,6,5
Step-by-step explanation:
We need to identify the domain and range of the function: input 1,3,5,7 output 8,7,6,5
Domain of function:
For any function domain is set of input values.
Range of function:
For any function range is set of output values.
So, for the given function we have : input 1,3,5,7 output 8,7,6,5
Domain = 1,3,5,7 (set of input values is domain of function)
Range = 8,7,6,5 (set of output values is range of function)

James invested $4,000 at 5% interest per year; how long will it take him to earn $200 in simple interest?
Answer:
It takes 1 year.
Step-by-step explanation:
You have to apply simple interest formula, I = (P×R×T)/100 where I represent interest amount, P is principle, R is interest rate and T is number of years :
[tex]I = \frac{PRT}{100} [/tex]
[tex]200 = \frac{4000 \times 5 \times T}{100} [/tex]
[tex]20000 = 20000T[/tex]
[tex]T = 1[/tex]
We, know that :
[tex] \underline{\boxed{\sf Interest \: amount = \dfrac{Principal \times Rate \times Time}{100}}}[/tex]
[tex] \underline{\boxed{\sf I = \dfrac{P \times R \times T}{100}}}[/tex]
By putting values, we have
[tex] \sf : \implies 200 = \dfrac{4000 \times 5 \times T}{100}[/tex]
[tex] \sf : \implies 200 \times 100 = 20000 \times T[/tex]
[tex] \sf : \implies 20000 = 20000 \times T[/tex]
[tex] \sf : \implies \cancel{\dfrac{20000}{20000}} = T[/tex]
[tex] \sf : \implies 1 = T[/tex]
[tex] \underline{\boxed{\sf T = 1 \: year}}[/tex]
It takes 1 year for him to earn $ 200 in simple interest.

Complete the statements about the key features of the graph of f(x) = x5 – 9x3.
As x goes to negative infinity, f(x) goes to ________ infinity, and as x goes to positive infinity, f(x) goes to _______ infinity.
Answer:
Negative and positive
Step-by-step explanation:
Complete the statements about the key features of the graph of f(x) = x5 – 9x3.
As x goes to negative infinity, f(x) goes to "NEGATIVE" infinity, and as x goes to positive infinity, f(x) goes to "POSITIVE" infinity.
The complete statement is:
As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity
The function is given as:
[tex]f(x) = x^5 - 9x^3[/tex]
Set x to 2
So, we have:
[tex]f(2) = 2^5 - 9(2)^3[/tex]
[tex]f(2) = -40[/tex]
Set x to 5
[tex]f(5) = 5^5 - 9(5)^3[/tex]
[tex]f(5) = 2000[/tex]
Notice that, as the value of x increases from 2 to 5, the function increases from -40 to 2000
Hence, the texts that complete the blanks are (a) negative and (b) positive, respectively

2x+5x=210
7x=210
x=30
Now,Putting '30' in eq 1 and eq 2
2*30=60
5*30=150
Therefore Alina got 60 Rs while Asim got 150 Rs

Suzette is opening an office cleaning business. Her competitor charges $35 per hour plus a $42 cleaning supply fee. Which inequality could be used to represent the situation where Suzette’s charges, S, would be no more than her competitor’s charges?
Answer:
[tex]S\le 35h+42[/tex]
Step-by-step explanation:
Given that:
Cleaning supply fee charged by the competitor = $42
The charges by competitor per hour = $35
Let the number of hours = [tex]h[/tex] hours
Charges for [tex]h[/tex] number of hours = Number of hours multiplied by Charges per hour = $35[tex]h[/tex]
Now, total charges by the competitor = Charges for [tex]h[/tex] number of hours + Charges by the competitor = $35[tex]h[/tex] + 42
Charges of Suzette's = [tex]S[/tex]
As per question statement, the Suzette's charges can not be more than the competitor charges. Therefore Suzette's charges must be lesser than or equal to the competitor charges.
So, the inequality can be written as:
[tex]S\le 35h+42[/tex]
Where [tex]h[/tex] represents the number of hours.

Rachel has a collection of 40 stuffed animals, of the animals, 3/8 are beats and 1/5 are dogs. The rest are other animals. How many other animals does she have?
Answer:
17 animals
Step-by-step explanation:
Rachel has a collection of 40 stuffed animals
3/8 are bears
= 3/8 ×40
= 120/8
= 15
1/5 are dogs
= 1/5×40
= 40/5
= 8
15+8
= 23
Therefore the number of animal she have left can be calculated as follows
= 40-23
= 17
Hence there are 17 animals left

A company that makes hair-care products had 200 people try a new shampoo. Of the 200 people, 12 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
A - 16.66666...%
B - 24 people
C - 6%
D - 6 people
Answer:
24
Step-by-step explanation:
first you multiply 200 by 12, Then you divide that by 100. your final product is 24, hope that helps
Answer:
C. 6%
Step-by-step explanation:
First we need to divide the amount of people who got the allergic reaction by how many people were there.
So: 12 ÷ 200 = 0.06
Now, we need to multiply 0.06 by a whole percent, the whole percent is 100.
So: 0.06 × 100 = 6
6% of the people had a mild allergic reaction.

Braulio and Alejandro are siblings. Three years from now, Braulio will be 3 times Alejandro's present age. At that time, Alejandro will then be half as old as Braulio. How old are Braulio and Alejandro? Show all work and circle your final answers
Answer: Braulio is 15 years old, and Alejandro is 6 years old.
Step-by-step explanation:
Let's define:
B = Age of Braulio
A = Age of Alejandro.
"Three years from now, Braulio will be 3 times Alejandro's present age"
We can write this as:
B + 3 = 3*A
"At that time, Alejandro will then be half as old as Braulio"
A + 3 = (B + 3)/2
Then we have a system of equations:
B + 3 = 3*A
A + 3 = (B + 3)/2
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate A in the second equation:
A = (B + 3)/2 - 3
Now we can replace this in the other equation to get:
B + 3 = 3*A
B + 3 = 3*((B + 3)/2 - 3)
B + 3 = (3/2)*B + 9/2 - 9
Now let´s move all the terms with B to the left side, and the other terms to the right side.
B - (3/2)*B = 9/2 - 9 - 3
-(1/2)*B = 9/2 - 18/2 - 6/2 = -15/2
B = (-2)*(-15/2) = 15
Braulio is 15 years old.
And from the first equation:
B + 3 = 3*A
15 + 3 = 3*A
18 = 3*A
18/3 = A = 6
Alejandro is 6 years old.
