Answer:
The answer is c
Step-by-step explanation:
This is because you subtract 6 to get 9 ≤ -3x then when you divide to get x by itself, then the sign has to flip so you end up with -3≥x. And when you put it on a numbers line the arrow or way it goes is the way the arrow is pointing, so if the sign is like this > it would go to the right on the number line and the converse is true as well please give me brainliest.

A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $26. Option B is a commission rate of 10% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?
Step-by-step explanation:
12,500.
Step-by-step explanation:
We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.
First of all we will find amount earned by salesperson with option A.
\text{Option A earnings}=40\times 25=1000Option A earnings=40×25=1000
The salespersons earns $1000 through option A.
Let x be the amount of weekly sales.
8% of x should be equal to 1000 for salesman to earn the same amount with the two options.
\frac{8}{100}x=1000
100
8
x=1000
0.08 x=10000.08x=1000
x=\frac{1000}{0.08}x=
0.08
1000
x=12500x=12500
Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.

How many solutions does the system of equations below have? y = 3x + 2 Y-2x = 4 a) More than 1 solution b) At least 1 solution c) Exactly 1 solution d) No solution
To determine how many solutions this system has, we must solve the system first. We start by using substitution to solve for x.
[tex]y = 3x + 2\\y - 2x = 4\\\\3x + 2 - 2x = 4\\\\x + 2 = 4\\\\x = 2[/tex]
Now we plug in what we found x back into one of the original equations to solve for y.
[tex]y = 3(2) + 2\\\\y = 6 + 2\\\\y = 8[/tex]
With this information we can now answer the question.
We can conclude that this system has C. exactly 1 solution, [tex](2, 8)[/tex].
The number of solutions does the system of equations is to be considered as the option c. Exactly 1 solution.
Calculation of the number of solution:Since
y = 3x + 2
And, y - 2x = 4
So, we can write
3x + 2 -2x = 4
x + 2 = 4
x = 2
Now
y = 3(2) + 2
= 6 + 2
= 8
hence, The number of solutions does the system of equations is to be considered as the option c. Exactly 1 solution.

f(x)=x^2+5x what is the functions degree? what is the leading coefficient?
Answer:
the correct answer is d
Step-by-step explanation:
The leading coefficient is negative, so the graph rises on the left and falls on the right.
Therefore as x approaches infinity, y will be approaching negative infinity.

Answer: 3/2
==========================================================
Explanation:
Pick any two points on the red line. I'll pick (0,1) and (2,4)
Those coordinates will be plugged into the slope formula below
m = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(2 - 0)
m = 3/2
This means we go up 3 and over to the right 2 when traveling along this red line.
A: UT= 104 m B: UT=104 m C: UT=112m D: UT=126m
Answer:
m∠R = 126° and UT = 104
Step-by-step explanation:
In the given triangles, two angles and one side is congruent so using ASA postulate both triangles are congruent.
IT can be written as:
ΔQRS = ΔTUV
When two triangles are congruent their respective sides and angles are congruent
So,
m∠R ≅ m∠U
And
UT = RQ
Using these
m∠R ≅ m∠U
[tex]10y-14 = 5y+56\\10y-5y-14 = 56\\5y = 56+14\\5y = 70\\\frac{5y}{5} = \frac{70}{5}\\y = 14[/tex]
Putting y = 14 in 10y-14
[tex]10(14)-14\\= 140-14\\= 126[/tex]
Hence,
m∠R = 126°
And
RQ = UT
[tex]14x-36 = 2x+84\\14x-2x-36 = 84\\12x = 84+36\\12x = 120\\\frac{12x}{12} = \frac{120}{12}\\x = 10[/tex]
Putting x = 10 in 2x+84
[tex]2(10)+84\\=20+84\\=104[/tex]
Hence,
m∠R = 126° and UT = 104
A jar contains only pennies, nickels, dimes, and quarters. There are 16 pennies, 18 dimes, and 28 quarters. The rest of the coins are nickels. There are 84 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
Answer:
I hope this helps you
Step-by-step explanation:
84-16=68
68-18=50
50-28=22
n=22
equation:84-(16+18+28)
Answer:
84 - (28+16+18)= n
Step-by-step explanation:
The parentheses are how many of the coins are not nickels. and if you add it then subtract it from the total amount you will get how many nickels were in the jar.

Step-by-step explanation:
this is a combination of indicated operations
the number on the left of the indicated operation is the original set
the number '1/4' next to R shows that you need to multiply certain numbers by 1/4
the subscript on the R's shows which row the multiplication needs to be done on...
in this case it is saying that 1/4 [tex]R_{2}[/tex] + [tex]R_{1}[/tex] will become the new
so multiply 1/4 by a number in the row [tex]R_{2}[/tex] and then add that to the corresponding number from [tex]R_{1}[/tex]
an example: (1/4 x 8) + 0 -------> 2
2 would be the new first number in the second row

D. 8.57
Step-by-step explanation:
Okay I'm not sure if I do these problems correctly, but I always get the right answer.
7/11 = 0.6363...
15/0.6363... = 23.5714...
23.5714...- 15 = 8.57
The value of x would be option D.) 8.57
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or
[tex]\dfrac{a}{b}[/tex]
Triangles ABC and DEF are similar.
The ratio would be
DE / AB = DF / AC
We know that
15 / 15 + x = 7 / 11
So,
7/11 = 0.6363
15 / 15 + x = 0.6363
By cross multiplication;
15/0.6363 = 15 + x
23.5714 = 15 + x
x = 23.5714 - 15
x = 8.57

Write a linear function f with f(4)=−3 and f(0)=−2
Answer:
y = -x/4 -2
Step-by-step explanation:
Linear function is in the form;
y = mx + b
The first point is (4,-3)
so we have;
-3 = 4x + b
The second point is (0,-2)
Thus;
-2 = 0(x) + b
b = -2
Put this in the equation above
-3 = 4x -2
-3 + 2 = 4x
4x = -1
x = -1/4
So the equation is;
y = -x/4 -2

Write a rule for the nth term of the sequence.
Use your rule to find a 100-
-11, 5, 21, 37, 53, ...
Answer:
The rule for given sequence is: a_n = -27+16n
And the 100th term is: 1573
Step-by-step explanation:
Given sequence is:
-11, 5, 21, 37, 53, ...
Here
[tex]a_1 = -11\\a_2 = 5\\a_3 = 21\\a_4 = 37[/tex]
First of all, we have to find if this is an arithmetic sequence
For that purpose, the common difference has to be found. Common difference, denoted by d, is the difference between consecutive terms of an arithmetic sequence
So,
[tex]d = a_2 -a_1 = 5-(-11) = 5+11 = 16\\d = a_3 -a_2 = 21-5 = 16\\d = a_4-a_3 = 37-21 = 16[/tex]
As the common difference is same, the sequence is an arithmetic sequence
General rule for arithmetic sequence is:
[tex]a_n = a_1+(n-1)d[/tex]
Putting values
[tex]a_n = -11+(n-1)(16)\\a_n = -11+16n-16\\a_n = -27+16n[/tex]
For 100th term,
Putting n=100
[tex]a_{100} = -27+16(100)\\a_{100} = -27+1600 = 1573[/tex]
Hence,
The rule for given sequence is: a_n = -27+16n
And the 100th term is: 1573
