Answer:
D
Step-by-step explanation:
D
Explanation: If it helps, plug both the x and y values in each inequality. For the first, 0 is greater than -5, so A is not the answer. For the second, 0 is less than 3, so B is not the answer. For the last, there is no equal sign, so D is not the answer. (In order to make the inequality true, it has to be a greater than or equal to sign.) Now, for the third, 0 IS greater than -4, making that inequality true.

The value of (fog)(-2) is -292
What is a composite function ?A composite function is a combination of two or more than two functions where the output of the previous function is the input to the next function.
Given
f(x) = 8 - 10x and g(x) = 5x + 4
To find
(fog)(x) where x = - 2
First we will find (fog)(x)
putting the value of g(x) in f(x)
(fog)(x) = 8 - 10(5x + 40)
= 8 - 50x - 400
= -50x - 392
(fog)(-2) = -50(-2) - 392
= 100 -392
= -292

When dividing 82 by 43, Linda estimated the quotient to be 2. Examine Linda’s work, and explain what
she needs to do next. On the right, show how you would solve the problem.
Answers
Answer:
82/43 = 1 and 39/43
Step-by-step explanation:
When dividing 82 by 43 , the operation follows;
82/43 = 1 and 39/43
This means the quotient is 1 and reminder is 39
However;
82/43 = 1.907 ------nearest whole number is 2.
so the quotient can be approximated to the nearest whole number as 2.
At the school store the cost of three markers and two pencils is exactly $2.20 while the cost of four markers and six pencils is exactly $3.40. How much would it cost to buy 1 marker and 2 pencils?
Answers
Answer:
[tex]\$0.92[/tex]
Step-by-step explanation:
Let cost of 1 marker be [tex]x[/tex] and 1 pencil be [tex]y[/tex]
From the question we get two equations
[tex]3x+2y=2.2\quad ...(i)[/tex]
[tex]4x+6y=3.4\quad ...(ii)[/tex]
Multiply the first equation by 3 [tex](i)\times3[/tex]
[tex]9x+6y=6.6\quad ...(iii)[/tex]
[tex]4x+6y=3.4\quad ...(iv)[/tex]
Subtracting the above equations [tex](iii)-(iv)[/tex] we get
[tex]5x=3.2\\\Rightarrow x=\dfrac{3.2}{5}\\\Rightarrow x=0.64[/tex]
[tex]4x+6y=3.4\\\Rightarrow y=\dfrac{3.4-4x}{6}=\dfrac{3.4-4\times 0.64}{6}\\\Rightarrow y=0.14[/tex]
One marker costs $0.64 and one pencil costs $0.14
Cost of 1 marker and 2 pencils is [tex]0.64+0.14\times 2=\$0.92[/tex].
The soccer team boughtt-shirts at cost for $7.50. They want to sellthem as a fundraiser for between $11.00 and $15.00. What percent increase could they charge?
Answers
Answer:
47% or 100%Step-by-step explanation:
Step one:
given data
cost of T-shirt = $7.50
they could sell for either $11.00 and $15.00.
Required
The percent increase in the price
% increase = (cost-sales)price/cost price
% increase = (7.5-11)/7.5*100
% increase = 3.5/7.5*100
% increase = 0.47*100
% increase =47%
OR
% increase = (7.5-15)/7.5*100
% increase = 7.5/7.5*100
% increase = 7.5/7.5*100
% increase =1*100
% increase =100%
The increase could be 47% or 100%

Multiplying by 606060 and subtracting 555 both impact the mean:

the length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 centimeters, find the dimensions of the rectangle
Answers
Answer:
26x47
Step-by-step explanation:
To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146
We simplify and get 6x - 10 = 146,
then divide both side by 6 and plus 10 both sides,
we will get
x = 26
Now we've found one of the length,
to find the other side we do 26 * 2 = 52, and subtract 52 from 146,
which would get 94, then we divide it by 2
94/2 = 47
The dimensions is 26x47

In the bakery 4 cupcakes in one box. If 6 cups
were placed in the box, there would be 20 boxes left
empty. If 3 cupcakes were placed in each box, it
would run out of 20 boxes. Calculate how many
cupcakes were
in the bakery.
Answers
Answer:
There were 240 cupcakes in the bakery
Step-by-step explanation:
Assume that the number of boxes used is x
∵ If 6 cups were placed in the box, there would be 20 boxes left
∴ The number of cups in each box = 6
∴ The number of boxes used = (x - 20)
→ Multiply the number of cups in each box by the number of boxes
used to find the total number of cups
∵ The number of cups = 6(x - 20)
∴ The number of cups = 6x - 120 ⇒ (1)
∵ If 3 cupcakes were placed in each box, it would run out of 20 boxes
∴ The number of cups in each box = 3
∴ The number of boxes used = (x + 20)
→ Multiply the number of cups in each box by the number of boxes
used to find the total number of cups
∵ The number of cups3(x + 20)
∴ The number of cups = 3x + 60 ⇒ (2)
∵ The number of cups is the same in the two cases
→ Equate the right sides of (1) and (2)
∴ 6x - 120 = 3x + 60
→ Add 120 to both sides
∴ 6x = 3x + 180
→ Subtract 3x from both sides
∴ 3x = 180
→ Divide both sides by 3 to find x
∴ x = 60
∴ The number of boxes used is 60
∵ In the bakery 4 cupcakes in one box
∵ The number of boxes is 60
∴ The number of cupcakes = 4 × 60
∴ The number of cupcakes = 240
∴ There were 240 cupcakes

The length of the base of an isosceles triangle is x. The length of a leg is 2x-6 The perimeter of the triangle is 23. Find x.
Answers
Answer: 2.20
Step-by-step explanation:
An isosceles triangle has two of its side equal. Since the length of of a leg is 2x-6, it means that the other length is also 2x-6 while the base is x.
We the add the sides together. This will be:
x + 2x - 6 + 2x - 6 = 23
5x - 12 = 23
5x = 23 - 12
5x = 11
x = 11/5
x = 2.20

plouto answer
Answer:
Yes, because the points in the plot are all very close to the line, which indicates a strong association.
Step-by-step explanation:
When the points in a scatter plot are very close to the line of best fit, there is a strong association between the two variables and the line of best fit can be expected to make reliable predictions.
So, yes, the line of best fit could be used to make reasonable predictions, because the points in the plot are all very close to the line, which indicates a strong association.
Assume lines p and q intersect to form adjacent angles 1 and 2.
If m∠1=(7x+6)°
and m∠2=(8x−6)°,
find the value of x such that p is perpendicular to q.
Answers
Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.
