Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20

Answers

Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

        x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..

2. What is 3/25 as a Percentage?

3. What is 3/16 as a Percentage?

Please help!

Answers

1. What I do is get the 7/50 to have the denominator as 100 so I just double the 50 and the seven and get 14/100 so it’s 14%.

2. Same thing except 25 goes into 100 four times so I multiple the 3 and 25 by four and get 12/100 so it’s 12%.

3. Do 3 divided by 16, and you get .1875. So that’s 18.75% or you can do 100 divided by 16 and get 6.25. Then you multiply the 6.25 times the 3 and get 18.75%

Find the value of x 8.5,9,7.5,6,7,x ;the mean is 8

Answers

Answer:

x= 10

Step-by-step explanation:

Mean is the sum of all values divided their number

(8.5+ 9 + 7.5 + 6 + 7 +x) /  6 = 8

(8.5+ 9 + 7.5 + 6 + 7 +x) = 8*6 = 48

(8.5+ 9 + 7.5 + 6 + 7 +x) =48

(38 +x) = 48

x= 48-38 = 10

What is a and b pls answer ASAP I need it !!! Plsss

Answers

Answer:

The value of a = 5.

the value of b = 6.

Step-by-step explanation:

Given the points on the line

(6, 10)(a, 8)(4, b)(2, 2)

Given that all of the points are on the same line and the line represents a linear function.

Thus, the slope between any two points must be the same.

First, determine the slope between (6, 10) and (2, 2)

(x₁, y₁) = (6, 10)

(x₂, y₂) = (2, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 10] / [2 - 6]

               = -8 / -4  

               = 2

Thus, the slope of the line = m = 2

Determine the value 'a'

(x₁, y₁) = (6, 10)

(x₂, y₂) = (a, 8)

Using the slope formula to determine the value of 'a'

Slope =  [y₂ - y₁] /  [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula

Slope =  [y₂ - y₁] /  [x₂ - x₁]

2 = [8 - 10] / [a - 6]

2(a - 6) = 8 - 10

2a - 12 = -2

2a = -2 + 12

2a = 10

divide both sides by 2

a = 5

Therefore, the value of a = 5.

Determine the value 'b'

(x₁, y₁) = (2, 2)

(x₂, y₂) = (4, b)

Using the slope formula to determine the value of 'b'

Slope =  [y₂ - y₁] /  [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula

Slope =  [y₂ - y₁] /  [x₂ - x₁]

2 = [b - 2] / [4 - 2]

2(4 - 2) = b - 2

8 - 4 =b - 2

4 = b - 2

b = 6

Therefore, the value of b = 6

Answers

Answer:

90

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

x + 70 =120       {Exterior angle theorem}

        x = 120 - 70

       x = 50

y = x     {Vertically opposite angles}

y = 50

z + 50 + 40 = 180          {Angle sum property}

 z + 90  = 180

          z = 180 - 90

          z = 90
