Is 6 hours correct guys?

Answer:

-22

Step-by-step explanation:

solve this equation by plugging -4 into x in the equation.

your new equation will look like

f(-4) = (-4)2 + 4(-4) + 2

solve the right side of the equation to get your answer of -22

Step-by-step explanation:

-35+13=-22

Answer:

1 find the value of x graph. i thinks x is 5-3

2 cant help you there.

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

1. Substitute for k(x) and solve.

  k(x) = 6x -12

  15 = 6x -12 . . . . substitute for k(x)

  27 = 6x . . . . . . add 12

  27/6 = x = 9/2 = 4 1/2 . . . . . divide by 6

2. Find f(x) = 7 on the vertical scale. Follow that horizontal line over to the graph. Follow the vertical line at that intersection down to the x-axis. It will be halfway between the lines marked 4 and 6. That is, the x-value is 5.

  f(x) = 7 = f(5)

  x = 5

Answer:

It will take 15 hours to read a book with 180 pages

Step-by-step explanation:

First, let's set up a ratio to find how many pages she reads per hour:

36:3 = 12:1

Now we can set up fractions to solve:

[tex]\frac{12}{1} =\frac{180}{x}[/tex]

Cross multiply:

[tex]12x=180[/tex]

Divide each side by 12:

[tex]x=15[/tex]

Answer:

If you use millimeters per minute, it would be easier.

Step-by-step explanation:

Answer:

Absolute value means how far are you from zero on the number line.

absolute value of | -18| for example is 18  

this means that you are at -18 on the number line that is 18 points away from zero.

and absolute value of |18 | is 18

this means that you are at point 18 on the positive direction on the number line. That is 18 points away from zero.

Answer:

The answer is the first one "put the compass point at A and set the width to be the length of line segment AB."

Step-by-step explanation:

They have to be equal, so you'll put the compass at point A and set it to be the length of AB, then you will put compass at point C, draw an arc that intersects the line, and label the point of intersection as "B"

Answer:

y = (-3/4)x - 2

Step-by-step explanation:

Start with the slope-intercept form y = mx + b.  Replace m with -3/4 and y with -2.  We then have y = (-3/4)x - 2.

Graphing this line:  Knowing that b = -2, plot the point (0, -2).  Find the x-intercept by letting y = 0 in the above equation and solving for x:

0 = (-3/4)x - 2, or (3/4)x = -2, or x = (4/3)(-2), or x = -8/3.  Plot this x-intercept (-8/3, 0).  Finally, draw a line through the points (0, -2) and (-8/3, 0).

Answer:

D

Step-by-step explanation:

y = 15 so 2/3 times 15 equals 30/3, which equals to 10

so far, you have 1/5 - 10 = 30

10 plus 30 equals to 40 so basically you have to find what times 1/5 equals to 40

200 times 1/5 is 40

Answer:

Step-by-step explanation:

Answers:

Length = 13 inches

Width = 11 inches

=====================================================

Work Shown:

w = width, some positive number

w+2 = length, since it is 2 inches more than the width

P = perimeter of the rectangle

P = 2(width + length)

P = 2(w + w+2)

P = 2(2w+2)

P = 4w+4

We're told that the perimeter is 48 inches. So we'll set the previous result equal to 48 and solve for w.

P = 48

4w+4 = 48

4w = 48-4

4w = 44

w = 44/4

w = 11

The width is 11 inches.

w+2 = 11+2 = 13

The length is 13 inches.

----------------

Checking the answers:

P = 2(L+W)

P = 2(13+11)

P = 2(24)

P = 48

The answers are confirmed.

Answer:

2.19 *10^7

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10.

If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

2.19 *10^7

Answer:

The original price of the TV was $609.51

Step-by-step explanation:

100% - 21% = 79%

Now the question were really asking here is "475.19 is 79% of what?"

475.19 = 0.79 * x

To get x we must take 475.19 and divide by 0.79, which is about 601.51

The original price of the TV was $609.51

7/9 < 5/6

We find the LCM of 9 and 6 which is 18.

For the first fraction, 6 multiplied by 3 is 18 so we multiply both the numerator and denominator by 3 to get:

5/6 = 5*3/6*3 = 15/18

For the second fraction, 9 multiplied by 2 is 18 so we multiply both the numerator and denominator by 2 to get:

7/9 = 7*2/9*2 = 14/18

We can see that 5/6 is greater than 7/9.
