Answer:

A.

Step-by-step explanation:

The third one is correct

Answer:

- 2

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 2, - 1 ] , then

f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )

f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus

average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

Answer:

17 1/4

Step-by-step explanation:

69/4 is already a fraction but we can turn it into a mixed number.

69/4 → 69 ÷ 4 → 17.25 or 17 1/4

Best of Luck!

Answer:

13

Step-by-step explanation:

[tex]d=\sqrt{(x2-x1)^{2} +(y2-y1)^{2} } \\d=\sqrt{(-9--4)^{2} +(6--6)^{2} } \\d=\sqrt{25 +144}\\d=\sqrt{169}\\d=13[/tex]

Answer:

10x>5x+100

Step-by-step explanation:

it says expression not equations so its < , >,

The profit would be on one side and the expenses on the other

No negatives

so it would be 5 times X (the amount of shirts) plus the base fee of $100

and they plan on selling it for 10$ each so (10x) is the profit

X = number of shirts

Answer:

64

Step-by-step explanation:

2 to the sixth power would be 2 multiplied by itself 6 times

Answer:

Edward earned $1300 interest in 4 years.

Step-by-step explanation:

Principal Amount = Initial Investment = $6500

Time t = 4 years

Interest rate r = 5% = 0.05 (it is taken in decimal i.e 5/100 = 0.05)

We need to find interest.

The formula used is: [tex]Interest= Principal\times r \times t[/tex]

Putting values and finding Interest

[tex]Interest= Principal\times r \times t\\Interest=6500\times 0.05 \times 4\\Interest= 1300[/tex]

So, the interest = $1300 in 4 years.

Edward earned $1300 interest in 4 years.

Answer:

That is true. More information below.

Step-by-step explanation:

A prime number has to have only two factors: 1 and itself. 1 only has one factor (itself) so it is, as you were saying, neutral.

Answer:

(8,9)

Step-by-step explanation:

The biggest number minus the smallest number.

Answer:  x= -8  or x = 1/2

Step-by-step explanation:

2x^2 + 15x = 8      Subtract 8 from both sides to let the whole equation equal 0

            - 8     -8

2x^2 + 15x - 8 = 0      Now find two numbers that if you multiply them, their product will be -16 and their sum will be 15. An example is the numbers 16 and -1.     16 times -1 is -16  and 16 plus -1 is 15.

Rewrite the whole equation in this form,

2x^2 +16x - 1x - 8 = 0      Factor on the left side

2x ( x + 8)  -1 (x + 8) = 0     Now factor out x + 8

(x + 8) (2x -1) = 0            Set each expression equal zero, because for the whole expression to equation to 0, either one of them or all of them have to equation zero.

x + 8 = 0        or   2x - 1 = 0  

  -8     -8                     +1  +1

   x = - 8                  2x  = 1

                                 x = 1/2

hi I just wanna talk ;)

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Writing this relation in set notation using curly braces:

{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}

The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.

Hence, this relation is a function.

We know that the domain is the set of all x values.

Thus, the domain is: {1, 2, 3, 4, 5}

We know that the domain is the set of all y values.

Thus, the range is: {-1, 0, 3, 5, 6}

Answer:

I believe its either 20 or 14

Step-by-step explanation:

8. You divide each side by 8

9. You multiply each side by 15.2

10. You multiply bith sides by 8. 7

11. You divide both sides by 3.14

Answer:

Answer:

x=16

Step-by-step explanation:

1/2 ( x - 4 ) = 1/3 ( x + 2)

distribute both sides

1 /2 (x−4)= 1/ 3 (x+2)

( 1 /2 )(x) + ( 1/ 2 )(−4) =( 1 /3 ) (x)+( 1/3 )(2)(Distribute)

1 /2 x+−2= 1 /3 x+ 2 /3

1 /2 x+−2= 1 /3 x+ 2 /3

Step 2: Subtract 1/3x from both sides.

1/2x -2 -1/3 x

x= 1 /3 x + 2/3  − 1/ 3 x

1 /6  x−2= 2/ 3

Step 3: Add 2 to both sides.

1 /6 x −2+2= 2/ 3  +2

1 /6 x = 8 /3

Step 4: Multiply both sides by 6.

6*( 1/6 x) =6*( 8 /3 )

x=16

Answer:

the percentage of 80L from 400L is 20%

Step-by-step explanation:

in order to find the percentage of something you need to divide the total amount from the number you want to find the percentage of:

80 / 400 = 0.2

we now multiply 0.2 by 100 to turn it into a percentage:

0.2 * 100 = 20%
