y varies inversely with x. y=15 when x=10, find y when x=5
For the function F(x) = 1/x+1 which of these could be a value of F(x) when x is close to -1?
Answer:
Option B, -10000
Step-by-step explanation:
Step 1: Find the number that would be valid
As the x value gets closer to -1, the y values go to positive and negative infinity. Therefore, the best value out of the options given would be -10,000 since it is the closest to negative infinity.
Answer: Option B, -10000

help idk how to do math
use the distributive property
Answer:
Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.
That probably isn't a good answer, here's what I found on google:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Step-by-step explanation:
I'll do #10 as an example:
(x-5)y
distribute the numbers- y(x)-y(5)
without the parentheses- yx-y5
you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.
Here's #11:
-4(2a-3b+c)
distribute the numbers- (-4*2a)-(-4*3b)+(-4c)
solve- -4*2= -8
-4*3= -12
-8a-(-12)b+4c
*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing
Hope this helps you.
what two numbers multiply to -36 and add up to 5
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

Solve the inequality and graph the solution.
3(x+5) > 12
Answer:
x > -1
Step-by-step explanation:
3(x + 5) > 12
Distribute
3x + 15 > 12
Subtract 15 to both sides
3x > -3
Sivide both sides by 3
3x/3 > -3/3
x > -1

-8 + 5 ( 1 + x) = 2x - 20
multi step equation, please solve ill give brainliest (with steps)
Answer:
The answer is x=-17/3
Step-by-step explanation:
The Steps:
-8 + 5(1 + x) = 2x - 20
-8 + 5 + 5x = 2x - 20
-3 + 5x = 2x - 20
-3 + 3x = -20
3x = -17
x = -17/3

to find floor area:
= 8 x 8
= 64
= Floor is 64m.
to find carpet: 8 x 8 x 75%
= 64 x 75%
= 64 x 0.75
= 48
a. The dimensions of the carpet are probably 8 by 8.
b. The area of the floor not covered by carpet is 64, hence 8 x 8.

The equation P = 2m + 15 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials? Explain your reasoning.
Answer:
50
Step-by-step explanation:
115 = p
115 = 2m + 15
-15 -15
100 = 2m
/2 /2
50 = m

At her brother’s birthday party, Lisa ate 80 pretzels, or 20% of a bag. A tape diagram. Lisa ate 20 percent out of 100 percent of a bag of pretzels. She at 80 pretzels out of question mark in the bag of pretzels. What steps should be used to find how many pretzels were in the whole bag? Check all that apply.
20 × 4 = 80
20 + 60 = 80
100 × 4 = number of pretzels in the bag
100 + 60 = number of pretzels in the bag
100 × 4 = 400 pretzels
100 + 60 = 160 pretzels
