Answer:

x > -9

Step-by-step explanation:

Use distributive property and you get

-5x - 35 < 10 (+ 35 on each side)

-5x < 45 (divide by - 5)

x > -9 (When you divide by a negative you flip the sign)

Answer:

X>-9

Step-by-step explanation:

Distribute

-5x-35<10

add 35 on both sides

-5x<45

Divide -5 on both sides and flip the sign since your dividing by a NEGATIVE number

x>-9

Third question I'm giving 50 points

marishachu [46]

Answer: B

Step-by-step explanation:

y = mx + mc

The perpendicular will have slope -1/m and intercept mc, which is

y = (-1/m)x + mc

For the answers you have to factor out a -1/m from both terms:

$$y = -\frac 1m x + mc \cdot -m \cdot -\frac 1m$\\$

$y = -\frac 1m (x + mc \cdot -m)$

$\boxed{\;\textbf{(B)}\ \,y = -\frac 1m (x - m^2 c)\;}$

20x+x-2=4 rational equation

laila [671]

Answer:

x = 2/7

Step-by-step explanation:

Step 1: Write equation

20x + x - 2 = 4

Step 2: Solve for x

Combine like terms: 21x - 2 = 4
Add 2 to both sides: 21x = 6
Divide both sides by 21: x = 6/21
Simplify: x = 2/7

Step 3: Check

Plug in x to verify it's a solution.

20(2/7) + 2/7 - 2 = 4

40/7 + 2/7 - 2 = 4

42/7 - 2 = 4

6 - 2 = 4

4 = 4
