6. If F(x) = -6(2x2 + 5x) - 9, what is the value of F(-4)?

Answers

Answer 1

Answer:

-81

Step-by-step explanation:

-6(2x² + 5x) - 9

substitute -4 for 'x'

-6[2(-4)² + 5(-4)] - 9

-6[2(16) + (-20) - 9]

-6(32 - 20) - 9

-6(12) - 9

-72 - 9 = -81

Answers

Answer:

b. x^4 + 4x^2 + 8x

Step-by-step explanation:

I took the test. Also the exponents need to be in descending order in order for the equation to be in standard form.

So b, starts with an exponent of 4, the decreased to just the x variable with an understood exponent.

What values of b satisfy 4(3b + 2)^2 = 64?

Answers

Answer:

The value of 0 can satisfy b.

Step-by-step explanation:

4(3b + 2)^2 = 64

(12b + 8)^2 = 64

(12b + 8)^2 = 64

144b + 64 = 64

144b + 64 - 64 = 64 - 64

144b = 0

144b / 144 = 0 / 144

b = 0

So, the value of 0 can satisfy b.

Answer:

b = [tex]\frac{2}{3}[/tex] or b = -2

Step-by-step explanation:

4(3b + 2)^2 = 64

Divide by 4 on both sides

(3b + 2)^2 = 16

Square root both sides

√(3b + 2)^2 = √16

3b + 2 = ±4

Subtract 2 on both sides

3b = ±4 - 2

Divide by 3 on both sides

b = (±4 - 2)/3

If 4 is positive, b is [tex]\frac{2}{3}[/tex]

If 4 is negative, b is -2

Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?

Answers

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces

Hello! Some assistance with this question would be really helpful (:

Answers

The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.

The median is the middle of the set of numbers (line them up from top to bottom).

In this case it should look something like:

68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78

If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.

Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.

ax^2+bx+c is the first degree polynomial of x which of these letters equal zero?

Answers

First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.
