Step-by-step explanation:

Step-by-step explanation:

Remove the parentheses

2x^2-6-8= -6

Cancel equal terms

2x^2-8=0

Move the constant to the right

2x^2=8

Divide both sides by 2

x^2=4

Simplify the equation

x=+2 or -2

The value of (fog)(-2) is -292

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

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

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.

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

Answer:

y = 7x -  6

Step-by-step explanation:

We are given the slope of 7 and the y-intercept of (0, -6).

We can easily write this in slope-intercept form.

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

Replace 'm' with '7' and 'b' with '-6'.

[tex]y=mx+b\rightarrow \boxed {y=7x-6}[/tex]

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.

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%

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.

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

Answer: -45/4 = -11 1/4

Answer:

Explained below.

Step-by-step explanation:

Denote the variable as follows:

M = male student

F = female student

Y = ate breakfast

N = did not ate breakfast

(a)

Compute the probability that a randomly selected student ate breakfast as follows:

[tex]P(Y)=\frac{n(Y)}{N}\\\\=\frac{198}{330}\\\\=0.60[/tex]

(b)

Compute the probability that a randomly selected student is female and ate breakfast as follows:

[tex]P(F\cap Y)=\frac{n(F\cap Y)}{N}\\\\=\frac{121}{330}\\\\=0.367[/tex]

(c)

Compute the probability a randomly selected student is male, given that the student ate breakfast as follows:

[tex]P(M|Y)=\frac{n(M\cap Y)}{n(Y)}\\\\=\frac{77}{198}\\\\=0.389[/tex]

(d)

Compute the probability that a randomly selected student ate breakfast, given that the student is male as follows:

[tex]P(Y|M)=\frac{n(Y\cap M)}{n(M)}\\\\=\frac{77}{154}\\\\=0.50[/tex]

(e)

Compute probability of the student selected "is male" or "did not eat breakfast" as follows:

[tex]P(M\cup N)=P(M)+P(N)-P(M\cap N)\\\\=\frac{n(M)}{N}+\frac{n(N)}{N}-\frac{n(M\cap N)}{N}\\\\=\frac{n(M)-n(N)-n(M\cap N)}{N}\\\\=\frac{154+132-77}{330}\\\\=0.633[/tex]

(f)

Compute the probability of "is male and did not eat breakfast as follows:

[tex]P(M\cap N)=\frac{n(M\cap N)}{N}\\\\=\frac{77}{330}\\\\=0.233[/tex]
