Evaluate f(x) = 5x2 - 4x - 9 for f(-2)

Hey there! I'm happy to help!

Let's see what makes 12x^5.

3·2·2·x·x·x·x·x

And for 8x^3...

2·2·2·x·x·x

We see that both of these have two 2s and 3 xs, so our GCF is 2·2·x·x·x which is 4x^3.

Have a wonderful day! :D

Answer:

b=(3x² – 5x – 2)

l=(2x² + 12x - 4)

perimeter= 2(l+b)

=2( 2x² + 12x - 4+3x² – 5x – 2)

=2(5x²+7x-6)

=(10x²+14x-12) units

Hope it helps:-)

Answer:

1. Reflection across y-axis and translated down 1 unit

2. 270 degree counterclockwise rotation and translated right three units.

Step-by-step explanation:

For number 1, when you reflect across the y-axis, the polygon is one unit above the intended location, so you would move it down one.

For number two, when you rotate it 270 degrees counterclockwise, it is to the left three units, so you would move it to the right three units.

Answer:

f(4) = 14

Step-by-step explanation:

To evaluate f(4), substitute x = 4 into f(x), that is

f(4) = 3(4) + 2 = 12 + 2 = 14

Answer:

The length needed to cut off is 12.55 cm

Step-by-step explanation:

The corrected question is:

you need a piece of paper to measure 64.25 cm. If you tape two together that each measure 38.4 cm, how much do you need to cut off?

Solution:

measurement/length of each paper piece = 38.4 cm

measurement/ length required = 64.25 cm

If length of one paper piece is 38.4 cm then if we tape 2 pieces together then the measurement or length is calculated as:

38.4 + 38.4 = 76.8 cm

So to calculate how much we need to cut off:

length required to cutoff = total length of two pieces - length  required

                                         = 76.8 - 64.25

                                         = 12.55 cm

So the length required to cut off is 12.55 cm

Answer:

a. Addition & division

Step-by-step explanation:

2x - 4 = 16   (adding 4 to both sides)

2x  = 16 + 4

2x = 20  (dividing both sides by 2)

x = 20/2 = 10

Hence we can see that the two operations are addition and then division

Step-by-step explanation:

254c = 333

Answer:

Q1: is 0

Q2: is 20

Step-by-step explanation:

Q1: Divide the numbers 0 ÷ 6 = 0

√8 × 0

√8 = 2√2

2 × 0 × √2

Apply rule 0 × a = 0

Q2: Apply exponent rule : (a × b)^n = a^n b^n

2^2(√5)^2 = 2^2 (√5)^2

2^2 = 4

4 (√5)2

(√5)^2 = 5

4 × 5

Multiply the numbers: 4 × 5 = 20

Answer:

y = -7x + 11

Explanation:

Just get y by itself. Subtract 7x from both sides. Substitute in each x value individually to get the next answers, which will be 25, 11, and -10.

CANDY diabeatise sgdigduejsdid

Answer:

Y=9

Step-by-step explanation:

Single out the variable, so subtract 3y from both sides.

7y-9-3y=3y+27-3y

4y-9=27

Then move the value to one side, so add 9 to both sides.

4y-9+9=27+9

4y=36

Then divide 36 by 4

4y/4=36/4

y=9

Answer:

.9274 is a integer

Step-by-step explanation:

rational numbers have to be able to be written as a fraction.

.9274 is not a whole number.

therefore it is an integer.

Answer:

x = 11/8

Step-by-step explanation:

9x + 4 = x - 7

9x - x = -7 - 4

8x = 11

divide both sides by 8

8x/8 = 11/8

x = 11/8

Answer:

-2/3

Hope This Helps :)

Subtract 12 from both sides

5 - 12 = k/4

Simplify 5 - 12 to -7

-7 = k/4

Multiply both sides by 4

-7 * 4 = k

Simplify -7 * 4 to -28

-28 = k

Switch sides

k = -28
