Answer: $x\leq 3$

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

$4x+8\geq 5x+5$

2) Subtract $5x$ from both sides:

$4x+8-5x\geq 5x+5-5x$

3) Simplify:

$-x+8\geq 5$

4) Subtract $8$ from both sides:

$-x+8-8\geq 5-8$

5) Simplify:

$-x\geq -3$

6) Divide both sides by $-1$ :

$\frac{-x}{-1} =\frac{-3}{-1}$

7) Simplify:

$x\leq -3$

natta225 [31]

If 5 x 6 = 30 you can figure out 8 x 6 by adding 6 three times to 30!

30 + 6 = 36

36 + 6 = 42

42 + 6 = 48 <-- the answer is 48!

step-by-step explanation:

original coordinates of C: (4, -2)

if reflected over y-axis: use the formula: (x,y) → (-x,y)

new coordinates: (-4, -2)

then if translated 5 units horizontally, there will be change in x axis:

new coordinates: (-4+5, -2) → ( 1, -2)

How many terms are in 10y2-3y+8

Sergio [31]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find how many terms are in $\pmb{10y^2-3y+8}$ .

$\triangle~\fbox{\bf{KEY:}}$

A term is a thing that's added or subtracted.

So let's compute the number of terms in this expression.

The first term is $\pmb{10y^2}$ .

Is anything added or subtracted from 10y²?

Sure! $\pmb{-3y}$ is subtracted from 10y².

Also, 8 is added to -3y.

Thus, this expression has 3 terms.

Hope it helps you out! :D

PLZ HELP! WILL MAKE A BRAINLIST <br>Which types of dilation are the given scale factors?

attashe74 [19]

Answer:

see explanation

Step-by-step explanation:

For a given scale factor k

If k > 1 then expansion

If k < - 1 then expansion in the opposite direction

If 0 < k < 1 or - 1 < k < 0 then contraction

k = - 2 ← expansion in opposite direction

k = 1.5 ← expansion

k = $\frac{1}{4}$ ← contraction

k = - $\frac{6}{7}$ ← contraction
