Step-by-step explanation:

Answer:

e = -2

Step-by-step explanation:

Simplifying

0.75(8 + e) = 2 + -1.25e

(8 * 0.75 + e * 0.75) = 2 + -1.25e

(6 + 0.75e) = 2 + -1.25e

Solving

6 + 0.75e = 2 + -1.25e

Solving for variable 'e'.

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

Add '1.25e' to each side of the equation.

6 + 0.75e + 1.25e = 2 + -1.25e + 1.25e

Combine like terms: 0.75e + 1.25e = 2e

6 + 2e = 2 + -1.25e + 1.25e

Combine like terms: -1.25e + 1.25e = 0.00

6 + 2e = 2 + 0.00

6 + 2e = 2

Add '-6' to each side of the equation.

6 + -6 + 2e = 2 + -6

Combine like terms: 6 + -6 = 0

0 + 2e = 2 + -6

2e = 2 + -6

Combine like terms: 2 + -6 = -4

2e = -4

Answer:

e = -2

Step-by-step explanation:

.75(8+e) = 2 -1.25e

Distribute

6 +.75e =2-1.25e

Subtract .75e

6 = 2 - 2e

Subtract 2 from each side

6-2 = 2-2e-2

4 = -2e

Divide by -2

4/-2 = -2e/-2

-2 =e

Answer:

Option A.

Step-by-step explanation:

The general form of a quadratic function is  

[tex]y=ax^2+bx+c[/tex]

It means, power of y should be 1 and highest power of x should be 2.

In option A,

[tex]y-3x^2=3(x^2+5)+1[/tex]

[tex]y-3x^2=3x^2+15+1[/tex]

[tex]y=3x^2+16+3x^2[/tex]

[tex]y=6x^2+16[/tex]

It is a quadratic function.

In option B,

[tex]y^2-7x=2(x^2+6)+7[/tex]

Here, power of y is 2. So, it is not be a quadratic function.

In option C,

[tex]y-2x^2=6(x^3+5)[/tex]

Here, highest power of x is 3. So, it is not be a quadratic function.

In option D,

[tex]y-5x=4(x+5)+9[/tex]

Here, highest power of x is 1. So, it is not be a quadratic function.

Therefore, the correct option is A.

Answer:

It is A

Step-by-step explanation: I took the test on edge 2020

Answer:

Here is the equation written in numbers:

\frac{5x+1}{2y^{2} }  

Now, we plug in 3 wherever we see x and 2 wherever we see y.

\frac{(5*3)+1}{2* 2^{2} }  

Now, we can start solving this.

\frac{15+1}{2*4}= \frac{16}{8}=2  

So, the answer is 2.

Step-by-step explanation:

Answer:

answer is 30

Step-by-step explanation:

5 times x is also 5 times 3. That gives 15. 1/2 of y^2 is also 1/2 of 4, which is also 2. Thus 15 times 2 is 30

Step-by-step explanation:

Answer:

a = 4/27 - b/54

Step-by-step explanation:

27a+1/2b=4

Subtract 1/2 b from each side

27a+1/2b - 1/2 b=4-1/2 b

27a = 4 - 1/2 b

Divide each side by 27

27a/27 = 4/27 - 1/2 b/27

a = 4/27 - b/54

Its 2.

This is the answer because you would use the slope formula which is y2-y1/x2-x1. YOu just plug in your values and solve.

Answer:

C.

Step-by-step explanation:

Parallel lines have the same slope but different y-int. So if our original equation is y = 2x + 1, then the other equation would have to be y = 2x + b, where b ≠ 1. Only answer C. works.

Answer:

The answer is C) y-1=2(x-3)

Step-by-step explanation:

Two equations are parallel if they have the same slope and different y-intercepts. In the answer (c) 2 represents the slope which is also the slope of the original equation. y=2x-5is the equation that you get when you distibute and isolate y.

The measure of angle 1 based on the information given will be 32°.

From the circle, we can see that an angle subtends outside the circle which is 102° while the angle that's inside the circle is given as 38°.

Therefore, the value of angle 1 will then be:

= 1/2(102° - 38°)

= 1/2 × 64°

= 32°

The value of the angle is 32°.

Answer:

B. 1/2

Step-by-step explanation:

2/3x + 2 = 2 1/3

Change the fraction to improper.

2/3x + 2 = 7/3

Subtract 2 on both sides.

2/3x = 7/3 - 2

Subtract like terms.

2/3x = 1/3

Multiply both sides by 3/2.

x = 1/3 × 3/2

x = 3/6

Simplify.

x = 1/2

Answer:

The answer is option b

2/3x+2=2 1/3

Convert the mixed fraction to an improper fraction

2/3x+2=7/3

Multiply through by 3

You will get

2x + 6 = 7

2x = 7 - 6

2x = 1

Divide both sides by 2

x = 1/2

Step-by-step explanation:

Answer:

Width = 2 feet

Length = 6 feet

Explanation:

Variables:

Perimeter = p

Length = l

Width = w

Equation:

2w + 2l = p

It is given that:

l = 3w

and

p = 16 feet

With this information, we can rewrite the equation (substitute)

2w + 2(3w) = 16

Simplify

2w + 6w = 16

Add

8w = 16

Divide both sides of the equation by 8

Width = 2 feet

Length = 3(w) = 3(2) = 6 feet

Multiply the ratio with 5.

8×5:5×5:2×5

40:25:10

The smallest share is 10.

Answer:

The smallest share is 10 birds.

Step-by-step explanation:

To find the smallest share, we must find the smallest number in the ratio. We divide this by the sum of the individual numbers in the ratios; and multiply by the amount to be shared.

The calculation is done as follows;

[tex] \frac{smallest share}{ total ratio}* quantity to be shared \\ \frac{2}{8 + 5 + 2} * 75 \\ \frac{2}{15}* 75 \\ \frac{150}{15} \\ 10 [/tex]

The rest can be calculated by;

[tex] \frac{8}{15} \times 75 = 40 \\ \frac{5}{15}*75 = 25 [/tex]

As a check, adding the three quantities gives you 75

40 + 25 + 10 = 75

Answer:

x= -7

Step by Step Explanation:

We can write them both like functions like this

A= 5x- 4

B= 3x+ 8

The output of A will be three times the output of B

A=3b

We replace with the functions

5x-4= 3

We solve for x

5x= -4= 9x + 24

5x- 9x= 24 + 4

-4x= 28

x= 28 - 4

x= -7

The output that makes the out put of A 3 times the output of B is -7
