math tests?
85

Answer: [tex]x = -10[/tex]

Step-by-step explanation:

Hey there! I hope these steps will help you accomplish this problem :)

Step 1: Remove the parentheses.

[tex]6x - 2x + 9 = -31[/tex]

Step 2: Simplify.

                             [tex]6x - 2x + 9[/tex] to [tex]4x + 9[/tex].

[tex]4x + 9 = -31[/tex]

Step 3: Subtract 9 from both of the sides.

[tex]4x = -31 - 9[/tex]

Step 4: Simplify.

                            [tex]-31 - 9[/tex] to [tex]-40[/tex].

[tex]4x = -40[/tex]

Step 5: Divide both of the sides by 4.

[tex]x = -\frac{40}{4}[/tex]

Step 6: Simplify.

                             [tex]\frac{40}{4}[/tex] to [tex]10[/tex].

[tex]x = -10[/tex]

Answer:

Step-by-step explanation:

Here you go mate

step 1

6x-(2x-9)=-31  equation

step 2

6x-(2x-9)=-31  simplify

6x+-1(2x-9)=-31

step 3

6x+(-1)(2x-9)=-31  distribute

6x+-1(2x)+(-1)(-9)=-31

6x+-2x+9=-31

step 4

(6x+-2x)+(9)=-31  combine the terms that are alike

4x+9=-31

step 5

4x+9(-9)=−31(-9)  subtract-9

4x=-40

step 6

4x/4=-40/4  divide by 4 because 4 is a number that can make the division easier

answer

x=-10

it is probably 113.1 because the other person said it so it has to be right

Given:

Total cost of the call = $7.75

The charge for the first minute was $ 1. Each extra minute cost $ 0.25.

To find:

The equation for this situation and the call duration.

Solution:

Let x be the call duration in minutes.

Remaining minutes after first one minute = x-1

Cost of first minute = $1

Cost of 1 extra minute = $0.25

Cost of (x-1) extra minutes = $0.25(x-1)

Total cost of call = Cost of first minute + Cost of extra minutes

[tex]7.75=1+0.25(x-1)[/tex]

[tex]7.75=1+0.25x-0.25[/tex]

[tex]7.75=0.25x+0.75[/tex]

[tex]7.75-0.75=0.25x[/tex]

[tex]7=0.25x[/tex]

Divide both sides by 0.25.

[tex]\dfrac{7}{0.25}=x[/tex]

[tex]28=x[/tex]

Therefore, the required equation is [tex]7.75=1+0.25(x-1)[/tex] and call duration is 28 minutes.

Answer:

The answer is below

Step-by-step explanation:

A function shows the relationship between two variables (that is an independent variable and a dependent variable).

The domain of a function is the set of all input variables (that is independent variables).

Given the function C(n) = 12.99n, C(n) is the dependent variable representing the cost and n is the dependent variable which is the number of jerseys.

Since the customer has to buy more than 25 jerseys, the domain is:

Domain = 25 < n ≤ ∝

Step-by-step explanation:

Answer:

5 and a half

Step-by-step explanation:

Because you can fit 2 liters in each can, to find how many you would need, divide 11 by 2, this would give you 5 and a half, 5.5.

It could be that they want you to round up to six or round down to five, so do consider that.

Answer:

If you put two things together it cannot be less than what was originally there.

Step-by-step explanation:

For example if you have two bowls of soup and you add them together you will have more soup.

Alec is incorrect because this inequality of model 1 + 2 < 4 i.e. the sum of two numbers is greater than either number.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Alec says the sum of two numbers can never be less than an either number.

Using a model  a + b < c

Substitute the values a = 1, b = 2, and c = 4 in the inequality of model

1 + 2 < 4

So, the sum of two numbers is greater than either number.

Hence, Alec is incorrect.

#SPJ2

Answer:

True

Step-by-step explanation:

The formula for the area of a circle is πr² where r is the radius. So if 3 is the radius, plug it into the formula:

π(3²)

Simplify it:

π(9)

This can be rewritten as:

9π

So, the answer is true

Answer:

The amount of the money earned left for the band to split is $357.5

Step-by-step explanation:

The amount the band earned for playing at the concert = $550.00

The percentage of the money earned taken by the manager = 15%

The percentage of the money earned the band is donating to charity = 20%

The amount of the money earned the manager takes = 15/100 × 550 = 82.5

∴ The amount of the money earned the manager takes = $82.5

The amount of the money earned that is donated to charity = 20/100 × 550 = 110

∴ The amount of the money earned that is donated to charity = $110

The amount of the money earned left for the band to split = $550 - $82.5 - $110 = $357.5.

Given:

The figure QRST.

The rule of translation is [tex]T_{(3,-2)}(QRST)[/tex].

To find:

The coordinate of vertices after translation.

Solution:

According to the given rule of translation is [tex]T_{(3,-2)}(QRST)[/tex], we get

[tex](x,y)\to (x+3,y-2)[/tex]

From the given figure it is clear that the vertices of QRST are Q(1,3), R(3,-3), S(0,-2) and T(-2,1).

Using the above rule, we get

[tex]Q(1,3)\to Q'(1+3,3-2)=Q'(4,1)[/tex]

[tex]R(3,-3)\to R'(3+3,-3-2)=R'(6,-5)[/tex]

[tex]S(0,-2)\to S'(0+3,-2-2)=S'(3,-4)[/tex]

[tex]T(-2,1)\to T'(-2+3,1-2)=T'(1,-1)[/tex]

Therefore, the coordinates of the vertices after translation are Q'(4,1), R'(6,-5), S'(3,-4) and T'(1,-1).

The ordered pairs for the vertices of T(3, –2)(QRST) are

[tex]\mathbf{Q' = (4,1)}[/tex]  [tex]\mathbf{R' = (6,-5)}[/tex]  [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]

The coordinates of QRST are:

[tex]\mathbf{Q = (1,3)}[/tex]

[tex]\mathbf{R = (3,-3)}[/tex]

[tex]\mathbf{S = (0,-2)}[/tex]

[tex]\mathbf{T = (-2,1)}[/tex]

The transformation rule of [tex]\mathbf{T(3,-2)}[/tex] is:

[tex]\mathbf{(x,y) \to (x + 3,y -2)}[/tex]

So, we have:

[tex]\mathbf{Q' = (1 + 3,3 -2)}[/tex]

[tex]\mathbf{Q' = (4,1)}[/tex]

[tex]\mathbf{R' = (3 + 3,-3 -2)}[/tex]

[tex]\mathbf{R' = (6,-5)}[/tex]

[tex]\mathbf{S' = (0 + 3,-2 -2)}[/tex]

[tex]\mathbf{S' = (3,-4)}[/tex]

[tex]\mathbf{T' = (-2 + 3,1 -2)}[/tex]

[tex]\mathbf{T' = (1, -1)}[/tex]

Hence, the ordered pairs for the vertices of T(3, –2)(QRST) are

[tex]\mathbf{Q' = (4,1)}[/tex]  [tex]\mathbf{R' = (6,-5)}[/tex]  [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]

So e is the answer

12.) The compound transformation should read

Dilation with center at origin and scale factor of 1/2

Reflection across the x-axis

Reflection across the x-axis rule is (x, y) -->(x, -y)

a is the answer b/c A(-1, -2) --> A'(-1/2, -1) --> (-1/2, 1)

PAGE 3

13.) The scale of the dilation is 1/4 b/c ---> 25*1/4 = 6.25 and 64*1/4 = 16

So 16*1/4 = 4 and 10*1/4 = 2.5, so e is the answer
