In this question, you have to isolate <em>x</em>.

First, use the distributive property.

3x+30=4x+32

Now that you have distributed, subtract the constants.

Use a inequality symbol to compare -3x+7 -10-2
abruzzese [7]
Hey there,

Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).

So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)

Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7). 

    -3
+   7
______
     4

Let's bring that "x" back, and the answer would be 4x for a while.

So far, 4x is the answer.
_____________________________________________________________

Now, Let's work on the other side.

We are talking about (<span>-10-2)

    -10
-      2
_______
</span>     -12

So, by solving the answer to (-10-2), we got -12.

So, let's determine what is greater . . . . . 

What \ is \ greater?

-12 or 4.

-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.

Your correct answer would look like . . . 

<span>(-3x+7) > (-10-2)
</span>
I really hope this helps you alot.

10(5 - n) - 1 = 29<br><br> n = ?<br> Help!
nydimaria [60]

n = 2

distribute and simplify left side of equation

50 - 10n - 1 = 29

49 - 10n = 29 ( subtract 49 from both sides )

- 10n = 29 - 49 = - 20

n = \frac{-20}{-10} = 2

QUESTION ATTACHED PLZ HELP NEEDED
saw5 [17]
Y = a (x + 3)² - 1

Let's take the point (-1;3)

3 = a ( -1 + 3)² - 1
3 = 4a - 1
4a = 4

Therefore a = 4/4 = 1

(x+3)² - 1
= x² + 6x + 9 - 1
= x² + 6x + 8

The answer would be y = x² + 6x + 8.

Hope this helps !

i o n f e h y=x3- 3x2- 9 x + 2 The largest and smallest values ​​of the function [ - 2 ; 4 ]At intervals.
Oksana_A [137]

Answer:

Step-by-step explanation:

Given the function :

y=x³ - 3x² - 9x + 2. The largest and smallest values ​​of the function at interval [-2, 4]

We substitute x values in the interval (-2 to 4) into the equation and solve for y

At x = - 2

y = (-2)³ - 3(-2)² - 9(-2) + 2 = 0

At x = - 1

y = (-1)³ - 3(-1)² - 9(-1) + 2 = 7

At x = 0

y = (-0)³ - 3(-0)² - 9(-0) + 2 = 2

At x = 1

y = (1)³ - 3(1)² - 9(1) + 2 = - 9

At x = 2

y = (2)³ - 3(2)² - 9(2) + 2 = - 20

At x = 3

y = (3)³ - 3(3)² - 9(3) + 2 = - 25

At x = 4

y = (4)³ - 3(4)² - 9(4) + 2 = - 18

Function is greatest at
