Answer:

e = 10

Step-by-step explanation:

Simplifying

0.5e + 20 = 25

Reorder the terms:

20 + 0.5e = 25

Solving

20 + 0.5e = 25

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-20' to each side of the equation.

20 + -20 + 0.5e = 25 + -20

Combine like terms: 20 + -20 = 0

0 + 0.5e = 25 + -20

0.5e = 25 + -20

Combine like terms: 25 + -20 = 5

0.5e = 5

Divide each side by '0.5'.

e = 10

Simplifying

e = 10

Answer:

e = 1

Step-by-step explanation:

0.5e + 20 = 25

0.5e = 5

e = 1

You subtract 20 from 25 to get 5. Then you divide 5 by 5 to get e = 1

Answer:

see explanation

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ) , thus

(0, 5 ) → (0, - 5 )

(- 1, 1 ) → (1, - 1 )

(- 3, 2 ) → (3, - 2 )

(- 4, 4 ) → (4, - 4 )

Answer:

y=-3x+6

Step-by-step explanation:

Answer:

y = -3x + 6

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

SO

m = -3

b = 6

Thus,

y = -3x + 6

Answer: 72

Step-by-step explanation:

From the question, we are informed that a disc jockey can play 7 records and that there are 9 records to select from for a particular segment of a radio show.

The number of ways that the program for the segment be arranged will be:

= 9! / 7!

= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (7 × 6 × 5 × 4 × 3 × 2 × 1)

= 9 × 8

= 72

Answer:

150 + 2x

The greatest common factor of 150 and 2x is 2. Factor out a 2 from both terms:

2(75) + 2(x).

Use the Distributive Property, A(B + C) = AB + AC, to rewrite the expression:

2(75 + x).

The expression 150 + 2x is equivalent to 2(75 + x).

Answer: -5/4

Step-by-step explanation:

A slope is also known as the gradient of a line. The slope of the given equation is -5/4.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The given line passes through two points (0,2) and (-4,7), therefore, the slope of the given line can be written as,

Slope, m = (7 - 2)/(-4 - 0) = 5/-4

Hence, the slope of the given equation is -5/4.

Answer:

3 gumballs and 5 jawbreakers = $3.00

Step-by-step explanation:

30 x 5 = $1.50 (One dollar and 30 cents)

50 x 3 = $1.50 (One dollar and 30 cents)

and if you add those together you get $3.00 because

50 + 50 = 100 or in this question $1.00 and when you add

$1.50 + $1.50 = $3.00

hope this helps!

Answer:

1. ASA

2. SSS and SAS

Step-by-step explanation:

1. We know that two angles are congruent, and the side in between them is congruent, so the postulate we can use is the ASA postulate

2. SSS and SAS. We know that two sides are congruent. We can figure out that AC = AC by the reflexive property so we can use the SSS postulate. We can also use the SAS because two sides are congruent and the angle in between them is congruent too.

Answer:

2M will be:

[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Therefore, the 2nd option is true.

Step-by-step explanation:

Given the matrix

[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]

Multiplying by 2 will basically be a scalar multiplication.

Therefore, multiply each of the matrix elements by a scalar.

[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]

       [tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]

        [tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Hence, 2M will be:

[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]

Therefore, the 2nd option is true.

Answer:

Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2

Step-by-step explanation:

We are given function: [tex]h(x)=-x^2-6x+17[/tex] (considering x is missed)

We need to find average rate of change  of the function over the interval [tex]- 6 < x < -2[/tex].

[tex]x_{1} = -6\\x_2 =-2[/tex]

Formula used to find average rate of change is: [tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}[/tex]

Finding f(x₁) and f(x₂)

[tex]We \ have \ x_1=-6\\h(x_1)= -x^2-6x+17\\h(x_1)=-(-6)^2-6(-6)+17\\h(x_1)=-36+36+17\\h(x_1)=17[/tex]

[tex]We \ have \ x_2=-2\\h(x_2)=-x^2-6x+17\\h(x_2)=-(-2)^2-6(-2)+17\\h(x_2)=-4+12+17\\h(x_2)=25[/tex]

Putting values in the formula of average rate of change

[tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}\\h(x_2)=25, h(x_1)=17, x_1 =-6 \ and \ x_2=-2\\Average \ Rate \ of \ Change =\frac{25-17}{-2-(-6)}\\Average \ Rate \ of \ Change =\frac{8}{4}\\Average \ Rate \ of \ Change =2[/tex]

So, Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2
