Answer:
-3x^4-3x+15x^2
Hope it helps
The 1st option
Answer:
- 3[tex]x^{4}[/tex] + 15x² - 3x
Step-by-step explanation:
Given
(5[tex]x^{4}[/tex] - 3x + 8x²) - (8[tex]x^{4}[/tex] - 7x²)
Remove the parenthesis on first and distribute second by - 1
= 5[tex]x^{4}[/tex] - 3x + 8x² - 8[tex]x^{4}[/tex] + 7x² ← collect like terms
= - 3[tex]x^{4}[/tex] + 15x² - 3x ← in standard form

What is the midpoint between the points (3,-1) and (-9,8)?
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
3+(-9)=3-9=-6
-6/2=-3
And for the y value you add the y values and divide by 2.
-1+8=7
7/2=3 1/2
Therefore, our midpoint is (-3,3 1/2)

Solve the equation -5(x-2)=-(x+6)
Answer:
[tex] \huge{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}} [/tex]
Step-by-step explanation:
[tex] \sf{ - 5(x - 2) = - (x + 6)}[/tex]
Distribute -5 through the parentheses in left hand side
Similarly, distribute ( - ) sign through the parentheses in right hand side
[tex] \longrightarrow{ \sf{ - 5x + 10 = - x - 6}}[/tex]
Move x to left hand hand side and change it's sign
Similarly, move 10 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 5x + x = - 6 - 10}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{ - 4x = - 6 - 10}}[/tex]
The negative integers are always added but posses the negative ( - ) sign
[tex] \longrightarrow{ \sf{ - 4x = - 16}}[/tex]
Divide both sides by -4
[tex] \longrightarrow{ \sf{ \frac{ - 4x}{ - 4} = \frac{ - 16}{ - 4}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 4}}[/tex]
Hope I helped!
Best regards! :D
Steps to solve:
-5(x - 2) = -(x + 6)
~Simplify both sides
-5x + 10 = -x - 6
~Subtract 10 to both sides
-5x = -x - 16
~Add x to both sides
-4x = -16
~Divide -4 to both sides
x = 4
Best Of Luck!
reduce the ratio of 70 and 50
Answer:
7:5
Step-by-step explanation:
70 and 50 can be divided by 10
hope this helps you :)
Answer:
7:5
Step-by-step explanation:
we will make the numbers 70 and 50 as low as they can be while still keeping the same ratio between the two numbers.
To do this we find the largest number that both 70 and 50 can be divided by. Then we divide both 70 and 50 by that number to get the new reduced ratio.
The largest number 70 and 50 can be divided by is 10. When we divide both numbers by 10, we get the new reduced ratio as follows:
7:5

Which angle relationship means two angles add up to 90
degrees?
When two angles add to 90°, we say they "Complement" each other.
So if two angles are complementary,
then the sum of their measures is 90 degrees.
For example, if we had a 62 degree angle and an 18 degree angle,
these two angles are complementary because they add to 90 degrees.

Step-by-step explanation:
Peyton plans to deposit her next paycheck into her savings account.she makes $12.50 per hour and her next paycheck will be h hours of work the expression 12.50h + b represents the amount of money in her savings account after she deposits her next paycheck what does b represent in the expression
Answer: Current savings account balance
Step-by-step explanation:
since the equation is y = mx + b
mx would be the starting point so she earns 12.50 per hour so it's the current amount she has is 12.50.
Sorry if it dosen't make sense.
The b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.
What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one operation such as addition, subtraction, multiplication, or division.
We have,
The amount earned per hour = $12.50
The amount earned in her next paycheck = $12.50h
where h = number of hours
The expression that represents the amount of money in her savings account after depositing the next paycheck:
= 12.50h + b
We need to find what b represents in this expression.
b will represent the amount already in the saving account before depositing the next paycheck.
Thus the b in the expression 12.50h + b represents the amount already in the saving account before depositing the next paycheck.

Here's a strange fact I recently found out:
"Scientists have long known that Africa is the cradle of human civilization. There, our ancestors shed most of their body hair around 2 million years ago, and their dark skin protected them from skin cancer and other harmful effects of UV radiation. When humans began leaving Africa 20,000 to 50,000 years ago, a skin-whitening mutation appeared randomly in a sole individual, according to a 2005 Penn State study. That mutation proved advantageous as humans moved into Europe. Why? Because it allowed the migrants increased access to vitamin D, which is crucial to absorbing calcium and keeping bones strong. "
