(5h^3-8h)+(-2h^3-h^2-2h)

First, you would distribute into parentheses but there is nothing

5h^3-8h-2h^3-h^2-2h

Now, separate all into common terms

(5h^3-2h^3)(h^2)(-8h-2h)

Now simplify

3h^3h^2-10h

Can somebody help me with that? Thank:)

The sum of the angles in a triangle is 180, so the equation will be :
2k+k+45= 180
add similar variables
3k+45=180
3k=135 (divide each side by 3)
k= 45
So 2k equals= 90
k=25
This is right angle triangle for your info!

Solve the inequality: -7y - 3x < 21

SashulF [63]

Answer:

x> -7/3y -7

Step-by-step explanation: -7y-3x<21

Step 1: Add 7y to both sides.

−3x−7y+7y<21+7y

−3x<7y+21

Step 2: Divide both sides by -3.

-3x/-3 < 7y+21/-3

x>-7/3y -7

Which logarithmic equation is equivalent to the exponential equation below? E^a=35

oee [108]

Answer:

a = ln 35

Step-by-step explanation:

Given e^a = 35, take the natural log of both sides, obtaining:

ln e^a = ln 35. Recall that ln e^x = x, which means that ln e^a = a.

Then a = ln 35.

Next time, please share the answer choices!

When making a horizontal translation your y-value changes and when making a vertical translation your x-value changes. true or f

Ann [662]

False
The horizontal translation is from left to right which affects the x-value while the vertical translation is up to down which affects the y-value

Good luck!

How to solve the system of equations algebraically for all values of x, y, and z

stich3 [128]

4x -3y + z = -10...............(1)
2x +y + 3z = 0...............(2)
-x +2y - 5z = 17...............(3)

First we multiply 3*(2) and add it to (1)
6x +3y +9z =0..................+(1)..................> 10x + 10z = -10......(4)

Then we multiply -2*(2) and add it to (3)
-4x -2y -6z =0 ...................+(3)................> -5x -11z = 17...........(5)

Multiply 2*(5) and add it to (4)
-10x -22z = 34...................+(4).................> -12 z = 24 ..............>>> z = -2

Substitute z in (4)............> 10x +10(-2) = -10.............................>>> x = 1

Substitute x and z in (2).....> 2(1) +y + 3(-2) = 0..................>>> y = 4

Solution (x,y,z) = (1,4,-2)
