Answers

Answer:

0 => -5

1 => -3

2 => 3

3 => 13

Step-by-step explanation:

No worries! To fill the table, we need to take the x values and insert them for the f(x) value.

The equation we're given is

f(x)=2x²-5

Starting with 0, we have

2(0)²-5

0²-5

0-5

-5

If we repeat for the rest of the values, we get the f(x) values listed above.

Answer: 0= -5 1=-3 2=3 3= 13

To answer this for every Number there is for x you have to plug it in

2(0)^2 -5
2(0)-5
0-5
=-5


2(1)^1-5
2(1x1)-5
2-5
=-3

A pair of pants that cost $75 is on sale for 20% off. What's the new price?

Answers

Answer:

60 dollars

Step-by-step explanation:

Answer:

$60

Step-by-step explanation:

Percentages are out of 100. Move the percentage sign twice in 20% to get 0.20.

Then, multiply 0.20 by 75. This gives you 15.

Lastly, subtract 15 from 75 (75-15), giving you $60 as your new price.

Answers

Answer:y=2x+4

explanation:

−10x+5y=20

Step 1: Add 10x to both sides.

−10x+5y+10x=20+10x

5y=10x+20

Step 2: Divide both sides by 5.

5y=10x+20

3x + 25 = 2(4x – 10) solve step by step

Answers

Answer:

x=9

Step-by-step explanation:

3x + 25 = 2(4x – 10)

3x + 25 = 8x-20

3x-8x=-20-25

-5x=-45

5x=45

x=9

The answer is: X=9 first step is to distribute 2 into 4x and -10 then move the 8x over behind the 3x, then combine 8x and 3x together to get -5x=-20-25 combine -20 and -25 to get -45 then divide -45 by -5 to get x=9

Polynomial Operations 1&2 Test 10 of 1610 of 16 Items Item 10 The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

Answers

Answer:

3x + 2

Step-by-step explanation:

The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

The shape of a poster = Rectangular shape

Hence:

The Perimeter of a Rectangle (Poster) = 2L + 2W

Where:

Length = Height = 7x + 10

Perimeter = 20x + 24

Therefore:

20x + 24 = 2(7x + 10) + 2W

20x + 24 = 14x + 20 + 2W

2W = 20x + 24 - (14x + 20)

2W = 20x + 24 -14x - 20

2W = 6x + 4

W = (6x + 4)/2

W = 3x + 2

Therefore, the width of the poster

= 3x + 2

At what point do the lines y = x - 8 and y y = - 3x + 16 (4, - 4) (3 ) (0, 16) (2) (11, 3) ( ) (6, - 2)

Answers

Answer:

(6, -2)

Step-by-step explanation:

Correct question

At what point do the lines y = x - 8 and y = - 3x + 16 intersects?

Equating both expressions;

x - 8 = -3x+16

Collect like terms

x+3x = 16+8

4x = 24

x = 24/4

x = 6

Substitute x = 6 into any of the equation

Recall that y = x - 8

y = 6 - 8

y = -2

Hence the point (x, y) where they intersects is at (6, -2)
