Answer:
-8+3x
Step-by-step explanation:
7 – 9x – 15 + 12x
We cannot solve since there is no equals sign, we can only simplify
Combine like terms
7 -15 -9x+12x
-8 +3x
The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.
<u>
For example:</u>

We do,

But, once again, this was an example. This would show and illustrate the rule of "raising a power".<span />
Answer:
(4,4)
y = 4
x = 4
Step-by-step explanation:
First we need to input y = 1/2x + 2 into 4x - 2y = 8.
4x - 2 (1/2x + 2) = 8 <-- Then solve
4x - 1x + -4 = 8
3x - 4 = 8
+4 +4
---------------------
3x = 12
3 3
x = 4
Now we need to use x and apply it to find y.
y = 1/2x + 2
y = 1/2(4) + 2
y = 2 + 2
y = 4
Now to graph go on the x axis (horizontal axis) and go to 4, then up 4 on the y axis.
You need to graph the point (4,4).
I hope this helps!
Answer:
27.50
Step-by-step explanation:
109.99=100%
10.999=10%
21.998=20%
27.4975=25%
so they are taking £27.4975 off the original price meaning the new price is £82.4925 but, because it is money, you would need to round this to two decimal places leaving the new price as £82.49
E(1,-4) F(1,-6) G(-3,-5) H(-3,-3)
