NEED ANSWER PLEASE WILL GIVE BRAINLIEST

Let fx) = 8x-7.
What is f4)?

Answer:

Here is the explanation of how I was taught to do it :)

Step-by-step explanation: In its easiest form, an A=4, B=3, C=2, D=1, F=0.

If the class is 2 credit.......Multiply each numeric grade value by the number of credits the course was worth

Add these numbers together

Divide 45 by the total number of credits you took, in this example,13.

Your Weighted by Credit Hour GPA = 3.46

It depends on your school. Sorry this was not the most clear, I was taught like 2 years ago, and now I kinda forgot but hopefully this helps a lil dont get mad :)

The answer is the second one

Answer/Step-by-step explanation:

1. (0, 3) and (-4, -3)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 3}{-4 - 0} = \frac{-6}{-4} = \frac{3}{2} [/tex]

2. (2, -5) and (0, 5)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - (-5)}{0 - 2} = \frac{10}{-2} = -5 [/tex]

3. (-5, -5) and (-3, 5)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-5)}{-3 -(-5)} = \frac{10}{2} = 5 [/tex]

4. (0, -5) and (5, 5)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - (-5)}{5 - 0} = \frac{10}{5} = 2 [/tex]

5. (-4, 5) and (1, 0)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 5}{1 - (-4)} = \frac{-5}{5} = -1 [/tex]

6. (-5, 1) and (5, -4)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 - 1}{5 -(-5)} = \frac{-5}{10} = -\frac{1}{2} [/tex]

7. (-1, 4) and (-2, 1)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 4}{-2 -(-1)} = \frac{-3}{-1} = 3 [/tex]

8. (-5, 1) and (5, 0)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 1}{5 - (-5)} = \frac{-1}{10} = -\frac{1}{10} [/tex]

9. (-5, -2) and (5, -3)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 -(-2)}{5 -(-5)} = \frac{-1}{10} = -\frac{1}{10} [/tex]

10. (-3, 2) and (-5, 3)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 2}{-5 -(-3)} = \frac{1}{-2} = -\frac{1}{2} [/tex]

Answer:

C

Step-by-step explanation:

Listen, just think about it.

If 5 times “x” is subtracted from 27 (so 27-5x) if the result/answer

(meaning its equal “=“ ) is 9+ than 4 times “x” (soo basically like 4x +9). If you put all of those 2 equations together you get 27 x 5x = 4x + 9.

(I use “x” to as the variable and remember when a variable is next to a number it means you have to multiply whatever that number is)

Answer:

25%

Step-by-step explanation:

1,000x4 would be 4 thousand, so the answer would be 1/4. 1/4 as a percent is 25%.

4x+6y=10

-

2x+5y=1

= 2x+y=9

2x=9-y       -1

9-y+5y=1    ( using 1)

4y=1-9

y=-8/4

y=-2

2x=9-(-2)

2x=11

x=11/2

Answer:

the answer is:

5x - 2x = 15 - 6

3x = 9

x = 3

Answer:

x = 11/3

Step-by-step explanation:

x2 + x = 11

Combine like terms

3x = 11

Divide both sides by 3

x = 11/3

Answer:

Step-by-step explanation:

Wholesale price was marked up by 30% and became $125.

Assume wholesale price is x. Expression will be;

125 = x + (30% * x)

125 = 1.3x

x = 125/1.3

x = $96.15

Retail price percentage = 125/96.15

= 1.30

= 130%

GOING SEVENTEEN SUPREMACY

Answer:

x=-24

Step-by-step explanation:

Answer:

It is -24.

Step-by-step explanation:

First distribute 2/3 on the left side, and distribute 1/2 on the other side. Now you have 1 /3 x + 8 =  1/ 6 x + 7 + (−3). Now, combine like terms. Now you should have 1 /3 x + 8 =  1 /6 x + 4. Now, subtract 1/6x on both sides. You should now have 1 /6 x + 8 = 4. Subtract 8 from both sides, and you should have 1/6x = -4. Now the last step is to multiply by 6 on both sides. Now you should get -24. Have a good day!

Answer: [tex]w = 10[/tex]

Step-by-step explanation:

Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.

Step 1: Let 6w will be our length and let the perimeter be 140 cm.

[tex]6w, P = 140 cm[/tex]

Step 2: Perimeter means that you add up all the 4 sides of the rectangle.

[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]

[tex]P = 140, 14w[/tex]

Step 3: Divide both sides 14 to get the single w variable.

[tex]\frac{140}{14} = \frac{14w}{14}[/tex]

Step 4: Simplify.

[tex]10 = w[/tex]

Step 5: Flip sides.

[tex]w = 10[/tex]

Answer:

63 centimeters

Step-by-step explanation:

What we know:

A cricle has a diameter of 20 cm.

To find circumference, use πd or 2πr.

3.14(10 * 2)

3.14(20)

62.8 cm, which rounds to 63 cm.

Answer:

8 1/3 hours : )

Answer:

c

Step-by-step explanation:

Answer:

Subtract 8 from both sides which lead it to 2=h/2, then multiply two for each side then it turns to 4=h

Answer:

I think "D"- 3(x + 3)

Step-by-step explanation:

as  3 years ago - x

so present age of shilpa  - x +3

~~~~~~~~~~~~~

present age  of sindhu - 3 (x+3)

i guess : )

Shilpa's age three years ago

Shilpa's age now = x + 3

Sindhu's age now = 3(x + 3)
