Answer:

x = -9/2  or -4.5

Step-by-step explanation:

-2x-5=4

Add 5 to each side

-2x-5+5=4+5

-2x = 9

Divide each side by -2

-2x/-2 = 9/-2

x = -9/2  or -4.5

Answer:

19)  ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]

20) -[tex]9^{2}[/tex] = -81

21)  [tex]2^{4}[/tex] = 16

Step-by-step explanation:

The only wrong ones are

19)  ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]

20) -[tex]9^{2}[/tex] = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is [tex]2^{4}[/tex] = 16

Everything else looks good.  Great job!

Answer:

Step-by-step explanation:

Oops I meant "there are 3! = 6 ways to permute ABTS that have TS."

There are 12 different combinations to display marvel that doesn't involve Steelie and the tiger.

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Given, Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf but does not want to put the Steelie and the Tiger next to one another.

We want the number of ways to permute the string ABST that has S and T separated.

Total ways of displaying marbles = 4! = 24

If S and T are together, then the permutation contains the consecutive pair ST or TS somewhere. We can count these possibilities by regarding ST or TS as a single symbol

permutation of getting them together = 2 * 3!

permutation of getting them together = 12

Thus,

total desired combination = Steelie and tiger do not come together

total desired combination = 24 - 12 = 12

therefore, There are 12 possible combinations of displaying marvel without making Steelie and tiger together.

Answer:

Step-by-step explanation:

Step one:

we are told that their joint amount is $62

let John's amount be x

and Pedro's amount be y

so that y=x+15

Step two:

The equation to represent the situation is

62=x+(x+15)

open the bracket and solve for x we have

62=x+x+15

62=2x+15

2x=62-15

2x=47

divide both sides by 2

x=47/2

x=23.5

John has $23.5

Answer:

The correct options are presented as follows;

ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent

Step-by-step explanation:

The coordinate of the preimage point A = (-2, 1)

The coordinate of the image point A' = (2, 1)

Similar for points B(-5, -2) and B'(5, -2), C(-3, -4) and C'(3, -4)

Which is equivalent to a reflection across the y-axis

Similarly, we have;

The coordinate of the preimage point A' = (2, 1)

The coordinate of the image point A'' = (-1, 2)

Which is equivalent to rotation of 90° counterclockwise which involves transforming a preimage (x, y) to an image (-y, x)

Similar for points B and B', C and C'

Therefore, because the reflection transformation, and the rotation transformation, are rigid transformation, the figures of the preimage and the image are congruent

Therefore, we have;

ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent.

Answer:

B

Step-by-step explanation:

f(x)=x (slope is 1, y-intercept is zero)

g(x) = (1/3)x (slope is (1/3), y-intercept is zero)

(1/3)x = (1/3)f(x)

Answer:

B

Step-by-step explanation:

as u notice the slop of f function is higher than g function so g(x) is approximately one third of function f and there are no shifts in g(×) so no need for sum of subtract .

Answer:

0.22 miles

Step-by-step explanation:

Let

A = Distance pumpkin A travels = 0.61 miles

Distance pumpkin B travels is 0.28 mile farther than Pumpkin A

[tex]B=0.28+A\\\Rightarrow B=0.28+0.61\\\Rightarrow B=0.89\ \text{miles}[/tex]

Distance pumpkin B travels is 0.06 miles further than pumpkin C

[tex]B=0.06+C\\\Rightarrow C=B-0.06\\\Rightarrow C=0.89-0.06\\\Rightarrow C=0.83\ \text{miles}[/tex]

To calculate how much farther pumpkin C travels than pumpkin A we have the subtract their distances

[tex]C-A=0.83-0.61=0.22\ \text{miles}[/tex]

So, pumpkin C traveled 0.22 miles more than pumpkin A.

The value of the phone after 2 years will be equal to $388.8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also represent the logical syntax's operation order and other properties.

Given that the cell phone costs $750 and loses 28% of its value each year. The value of the phone after 2 years will be,

The value of the phone after 2 years will be calculated as,

Cost of phone = 750 x ( 0.28 )²

Answer:

-2 and 2

Step-by-step explanation:

When you look at the graph, you see that the line is in a U shape. We are trying to see what the value of g(x)=4. Since g is represented by the graph, the equation equals 4. The 4 in the equation is positive so you would look at the graph for a positive 4. There are 2 positive 4's on the graph; one on the x axis and one on the y axis. If you look at the U-shaped line, you see that it passes the 4 on the y axis. (the point -2,4 has the 4 as y and the point 2,4 has 4 as y). This makes the answer -2 and 2 because both the numbers have 4 as the y when you put them as points.

Answer:

Option (D)

Step-by-step explanation:

Formula to get the average rate of change of the function f(x) between two points x = a and b is,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to calculate the average rate of change between x = 0 and x = 2.

From the graph attached,

f(0) = -2

f(2) = 6

Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]

                                                          = [tex]\frac{8}{2}[/tex]

                                                          = 4

Option (D) will be the correct option.
