PLEASE FACTOR these POLYNOMIALS and EXPLAIN HOW
1. 12x - 3x^2
2. 20 - 240x^2

Answers

Answer 1

Answer:

Answer:

1. 3x(4-x)

2. 20(1-12x^2)

Step-by-step explanation:

1. Both of the monomials have an x and can be divided by 3. You can factor out 3x, getting the equation I wrote out on the answer part.

2. Both of the monomials can be divided by 20, so you can once again factor out 20, getting the equation I wrote out on the answer part.

Answers

the slope is 2 because remember, y= mx+b
m= slope
the slope is always multiplied by x

Your equation is in slope-intercept form which is represented by

y = mx + b

In the formula,
y = your y-axis coordinate
m = slope
x = x-axis coordinate
b = the y intercept (where the line crosses the y axis)

So with the equation

y = 2x - 3/2

The slope is 2

In the equation 6-A/4=-3, what would A be?

Answers

I don't know. Let's solve it together. Then we'll both know what 'A' is,
and PLUS, you'll know how to find it.

6 - A/4 = -3

We want to get 'A' all by itself on one side of the equation,
and everything else on the other side.

Subtract 6 from each side: - A/4 = -9

Multiply each side by 4 : -A = -36

Multiply each side by -1 : A = 36

Did you follow that ?

-a / 4 + 6 -6 = -3 - 6
-a / 4 * 4 = -9 * 4
-a = -36
a = 36

the answer to the question 7 is the last one

You want to buy the bicycle that is $116. You already have $43.50 saved and plan to save an additional $7.25 every week.Part A: Write and solve an equation to find the number of weeks you need to save before you can purchase the bicycle.

Part B: How much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? Explain your reasoning.

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.
