Answer:
Step-by-step explanation:
-4 > x / -7....multiply both sides by -7, and flip the sign
-4 * -7 < = x
28 < x....or x > 28
yes, they are both the same.
28 < x ....this is saying that 28 is less then x
x > 28....this is saying that x is greater then 28
so there both saying the same thing
Answer:
2)8%
3)=
$
26.46
4)multiply $1.50 and 60%, which will give you 0.9. now multiply $1.50 and 0.9 and that'll give you$1.35. lastly, add $1.50 and $1.35 and that'll give you the answer which is $2.85.
5)15 % of $1580 is $237
6)25%

We have to simplify and get the value of x from this inequality given:
Given inequality,
Now let's simplify by using distributive property,
We need to find x, so let's isolate x to the letter side of the inequality for calculation at ease.
Now, dividing -2 from both sides.
Note : As we are dividing a negative number from both sides, the sign of the inequality will be <u>reversed</u>.
Now subtracting -7 from both sides,
Or, Interval of the equal ![(- \infin, -7 ]](https://tex.z-dn.net/?f=%28-%20%5Cinfin%2C%20-7%20%5D)

First you graph it using a graphing calculator, you look at the table of values to find out one point in which y= 0. The first one that comes up is when x=1.
If you don't have a graphing calculator you can use trial and error by inputing some numbers into x until you get y= 0.
Once you have an x value which makes y=0, you can start factorizing it.
you divide 6x3 +4x2 -6x - 4 into (x-1) which is when y =0
to get 6x2+10x+4
This can be used to write the polynomial as (x-1)(6x2 +10x+4)
you then factorize the second bracket, 6x2 +10x+4.
you can take the 2 outside to give you 2(3x2 +5x+2)
you can factorize this to become 2(3x+2)(x+1)
Now you just substitute your factorized second bracket into your unfactorized second bracket to give you 2(3x+2)(x+1)(x-1).
From this you can deduce that k= 1
Answer:
-2
Step-by-step explanation:
To find the slope of a line, you need to find the 
between two points. I will be using the points (-3, 2) and (-1, -2).
= 
= 
= 
= -2
