Answer:

−2x

Step-by-step explanation:

Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

Given:

A sum of money is divided between A,B and C in the ratio 9:8:7.

Total sum is 480.

To find:

The part of money A get.

Solution:

Let A, B and C get 9x, 8x and 7x respectively.

Total sum is 480.

[tex]9x+8x+7x=480[/tex]

[tex]24x=480[/tex]

Divide both sides by 24.

[tex]x=\dfrac{480}{24}[/tex]

[tex]x=20[/tex]

Now,

[tex]A\ get =9x[/tex]

[tex]A\ get =9(20)[/tex]

[tex]A\ get =180[/tex]

Therefore, amount received by A is 180.

Answer:

-5x-8-11y

Step-by-step

Because you shift 10x to -10x and then 5x-10x = -5x

You leave the -8 the same

You do 3y to -3y and  then do -3y -8y = -11y

Hence altogether you get, -5x -8 -11y

Answer:

r = 1/3

Step-by-step explanation:

3r + 4 = 5 Move the 4 to the other side of the equation.

3r = 5 - 4 Subtract

3r = 1

3r/3 = 1/3 Divide both sides by 3

r = 1/3

Answer:

z−181=−170

Step 1: Add 181 to both sides.

z−181+181= −170+181

z=11

Using translation concepts, the sequence that is used to obtain Figure A'B'C'D' is given by:

Reflection about the y-axis followed by a translation to the left by 2 units.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Considering the vertices, the changes have the following pattern:

(x,y) -> (-x,y) -> (-x -2, y).

At step (x,y) -> (-x,y), the function is reflected over the y-axis. Then, at step (-x,y) -> (-x -2, y), the function is shifted left 2 units, hence the correct option is given by:

Reflection about the y-axis followed by a translation to the left by 2 units.

Answer:

11 hours

Step-by-step explanation:

Let's say Karen makes x hours babysitting and y hours giving music lessons.

Because she worked a total of 18 hours, we know that x + y = 18.

5 * x is how much money she earns babysitting for x hours, while 12 * y is how much money she earns giving music lessons for y hours. Adding them up gives her total revenue:

5x + 12y = 139

We now have a system of equations. Let's multiply both sides of x + y = 18 by 12:

12 * (x + y) = 18 * 12

12x + 12y = 216

Now, subtract 5x + 12y = 139 from 12x + 12y = 216:

     12x + 12y = 216

-     5x + 12y = 139

_________________

       7x + 0y = 77

Divide both sides by 7:

x = 11

Thus, Karen spent 11 hours babysitting.

Answer:

Switch x and y.

[tex]\frac{1}{8} (x-4)^{3}[/tex]

Step-by-step explanation:

Switch the x and y, so the equation would read as:

[tex]x = \sqrt[3]{8y} +4[/tex]

Then solve for y.

[tex]x = \sqrt[3]{8y} + 4\\\\\\x - 4 = \sqrt[3]{8y} \\\\\\(x-4)^{3} = 8y\\\\\\\\\\\frac{1}{8} (x-4)^{3}[/tex]

Question 16

Given

Two golfers completed one round of golf.

The first golfer had a score of +6 and the second golfer had a score of -3.

To determine:

How many more shots did the first golfer take?

Explanation

Let 'n' be the number of shots taken by the first golfer

Since the first golfer had a score of +6 and the second golfer had a score of -3.

It means the 1st golfer must be 6 over par, and the 2nd golfer is still under 3.

Hence, we can map the situation using an equation

[tex]-3+n=6[/tex]

Adding -3 to both sides of the equation

[tex]-3+n+3 = 6+3[/tex]

[tex]n = 9[/tex]

Therefore, the 2nd golfer took 9 more shots.

Answer:

(13y + 15) -9y

-117y - 135

Step-by-step explanation:

Distribute -9y to the inside numbers in the parentheses  -117y and -135 are not compatible to each other ( because the -135 doesn't have a y ) so that would give you your final answer of:

-117y -135

13/8a - 5/8

Step-by-step explanation:

the only terms you can combine are 9/8a and 4/8a. You can add the fractions together to create 13/8a. the -5/8 can't be combined since it doesn't have an a

13/8a - 5/8

Answer:

= 3.5 miles per hour

Showing Work

This is a fraction equal to

7 miles ÷ 2 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2

7 miles ÷ 2

2 hours ÷ 2

=

3.5 miles

Answer:

14.6

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The letter m is usually used to refer to the slope. To calculate it, we divide the change in y over the change in x.

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In order to find this, we must find at least 2 coordinates that we know the function passes through.

In this case, we can see that the function passes through the point (3,0) and (0,-2).

[tex]m=\frac{0-(-2)}{3-0} = \frac{2}{3}[/tex]

Now that we know that the slope is [tex]\frac{2}{3}[/tex] we can ignore options C and D since [tex]\frac{3}{2} \neq \frac{2}{3}[/tex]

The y-intercept is the y value were the function touches the y axis.

In this case, we can see that the only point where the function touches the y axis (the vertical one) is -2

Answer:

y= 3x - 4

Step-by-step explanation:

hope this helps.

You have to find the unit rate, which in this case means the amount of fish you need per serving of soup.

If 16 oz of fish makes 24 servings, then 16/24 oz = 2/3 oz makes 1 serving.

Now multiply both quantities by 10, so that 10 servings require 20/3 oz ≈ 6.67 oz of fish.

A more direct way to do this is to solve for x in the following equation:

(16 oz fish) / (24 servings) = (x oz fish) / (10 servings)

Then (omitting units)

x = 10 • 16 / 24 = 20/3
