For (-1,2) you go to the left one and up two.
For (-3,6) left three up six
For (4,8) right four and up eight

Answer:

So for each point's numbers you have the x and the y. The first is the x, 2nd y in the parenthesis.

On the graph you start with the x axis, x in the middle is 0 to the left is the negative #'s and on the right: positive. Y axis is top positive, bottom negative! Now put the numbers on the axis' and then plot the points!

Hope this helps!!! :)

Jane deposits coins into her piggy bank each day. On the first of the month, Jane deposits 11 coins. Each day after that she deposit 7 more coins. What is the equation that defines how many coins she deposits after the nth day?

Answers

Answer:

11 + 7n

Step-by-step explanation:

Here, we want to write an equation that represents the the number of coins deposited after the nth day

Mathematically,

there are 11 coins

We now proceed to add;

7 * n = 7n to what we have

So finally to get the number of coins , we add up

That will be:

11 + 7n

Jing just got a new job. She started at a pay rate of $12.50 per hour and will get a $0.50 raise each year. Max started a job where is salary is found by the equation y=x+10, where x is the number of years. What is the initial value for Jing?

Answers

Answer:

initial value for Jing is $12.50.

Step-by-step explanation:

It is given that Jing started at a pay rate of $12.50 per hour and will get $0.50 per year. So, 0.50 is slope and y intercept is 12.50 for this equation.

The y intercept represents the initial value for the Jing.

So, initial value is $12.50.

Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?

Answers

Answer: Michael pays $12.19 for the headphones including the tax.

Step-by-step explanation:

The initial price of the headphones was $15.50

When Michael uses his coupon, the price is decreased by $4, then the new price will be:

$15.50 - $4 = $11.50

Now Michael must pay 6% for taxes (on the discounted price), then he must pay:

$11.50 + (6%/100%)*$11.50

$11.50 + 0.06*$11.50

$11.50*1.06 = $12.19

Then Michael pays $12.19 for the headphones including tax.

plug in 442 for P

442= 2(4w- 9) + 2W

From 20 tons to 99 tons? Increase or decrease?

Answers

Answer:

increase in weight

Step-by-step explanation:

Answer:

Increase.

Step-by-step explanation:

20 is larger than 99. if one ton is 2000 pounds then 20 tons are 40,000 pounds. So 99 times 2000 is 198,000 pounds, which is larger than 40,000.

Summary: 20 tons (40,000 pounds) < 99 tons (198,000) pounds

Answer:

  x = 23

Step-by-step explanation:

Eliminate parentheses, separate the variables and the constants, divide by the coefficient of the variable.

  7(x +4) = 9(x -2) . . . . . given

  7x +28 = 9x -18 . . . . . eliminate parentheses using the distributive property

  28 = 2x -18 . . . . . . . . . subtract 7x*

  46 = 2x . . . . . . . . . . . . add 18

  23 = x . . . . . . . . . . . . . divide by 2

The solution is x = 23.

Check

7(23+4) = 9(23-2)   ⇒   7·27 = 9·21 . . . true (=189)

__

* We choose to subtract 7x instead of 9x so that the resulting x-term has a positive coefficient.

_____

Additional comments

The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. So, when we say "subtract 7x", we mean that value is subtracted from both sides of the equation. Subtracting a value, or adding its opposite, is a way to remove a term from a place in the equation where you don't want it.

Here, the smaller x-coefficient is on the left, so we choose that term to subtract. That leaves the remaining x-term on the right (with a positive coefficient). We don't want any constants there, so we add the opposite of that constant. (The opposite of -18 is 18, so that is what we add--to both sides.)

__

Sometimes you will be told differently. You will be told to "put that over there and change its sign" or "cross-multiply". These instructions are based on appearance. The fundamental, always-applicable rule is "do the same thing to both sides of the equation." With practice and understanding, you can begin to think in terms of these shortcut suggestions.
