Answer: b=14

<u>Simplify both sides of the equation</u>

<u></u>(2)(b)+(2)(-4)=20(Distribute)\\2b+-8=20<u></u>

<u></u>

<u>Add 8 to both sides</u>

<u></u>2b-8+8=20+8\\2b=28<u></u>

<u></u>

<u>Divide both sides by 2</u>

<u></u>2b/2=28/2\\b=14<u></u>

Answer:

b = 14

Step-by-step explanation:

2(b - 4) = 20 \\ 2b - 8 = 20 \\ 2b = 20 + 8 \\ 2b = 28 \\  \frac{2b}{2}  =  \frac{28}{2}  \\ b = 14

If 48% of the students in a certain college are female and there are 1440 female students, what is the total number of students
Andrews [41]

Answer:

3000 students

Step-by-step explanation:

If 48% of the students are female, and there are 1440 female students, we can set up a percentage proportion, assuming x is the total amount of students.

\frac{1440}{x} = \frac{48}{100}

We can use the cross products property to find the value of x.

1440\cdot100=144000\\\\144000\div48=3000

Hope this helped!

&lt;RQT is a straight angle. What are m&lt;RQS and m&lt;TQS​
never [62]

Answers:

  • x = 11
  • angle RQS = 106 degrees
  • angle SQT = 74 degrees

===========================================================

Explanation:

Straight angles are always 180 degrees in measure.

The two smaller angles shown add up to 180

(angle RQS) + (angle SQT) = angle RQT

(9x+7) + (6x+8) = 180

(9x+6x) + (7+8) = 180

15x+15 = 180

15x = 180-15

15x = 165

x = 165/15

x = 11

From here, we then know that,

  • angle RQS = 9x+7 = 9*11+7 = 99+7 = 106 degrees
  • angle SQT = 6x+8 = 6*11+8 = 66+8 = 74 degrees

Note how the two results add to 106+74 = 180 to help confirm the answers.

Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.
sashaice [31]

Answer: Because the a-value is negative.

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k    where

  • "a" is the vertical stretch
  • -a is a reflection over the x-axis
  • h is the horizontal shift (positive = right, negative = left)
  • k is the vertical shift (positive = up, negative = down)

Given: g(x) = - (x + 1)² - 3

                    ↓

                 a= -1

Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
