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
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

Answer:
7x + 15y
Step-by-step explanation:
4x+ 3 ( 5y + x)
Step 1: remove the brackets by multiplying 3 with (5y + x)
4x+ 15y + 3x
Step 2: add the 4x and 3x
7x + 15y
Answer:
[tex]=7x+15y[/tex]
Step-by-step explanation:
[tex]4x+3\left(5y+x\right)[/tex]
[tex]3(5y+x)[/tex]
[tex]15y+3x[/tex]
[tex]=4x+15y+3x[/tex]

Find the value of x. Then find the angle measures of the triangle.
3x°
40°
Sum of angle
measures: 180°
Answer:
x=35°
3x= 105°
Step-by-step explanation:
[tex]40 + 3x + x = 180[/tex]
[tex]40 + 4x = 180[/tex]
[tex]4x = 180 - 40[/tex]
[tex]4x = 140[/tex]
[tex]x = \frac{140}{4} [/tex]
[tex]x = 35[/tex]
[tex]3x = 3(35) \\ 105[/tex]

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

3(x+5)=15
A.3
B.0
C.1/3
Answer:
x=0
Step-by-step explanation:
letter B
Answer:
B
Step-by-step explanation:
Take the three outaide the parentheses and distribute to both terms inside the parentheses. You would then get 3x+15= 15
subtract 15 from the left and right.
3x=0
Which means that x=0/3
So x=0

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.
