Answer:
x > 6
Step-by-step explanation:
1.) Distribute - 3 through the parenthesis
7x-3(4x-8)<6x+12-9x
7x-12x+24<6x+12-9x
2.) Then collect like terms
7x-12x+24<6x+12-9x
7x-12x+24<-3x+12
7x-12x+24<-3x+12
-5x+24<-3x+12
3.) Move the <u>variable</u> to the left and change the sign
-5x+24<-3x+12
-5x+3x+24<12
4.) Move the <u>constant</u> to the right and change it's sign
-5x+3x+24<12
-5x+3x<12-24
5.) Collect like terms
-5x+3x<12-24
-2x<12-24
6.) Calculate the difference
-2x<-12
7.) Divide both sides by -2 and flip the inequality sign
-2x<-12
x>6
B.
It can first be factored by splitting to:
(x + 1)(x^2 +4)
And (x^2 + 4) splits to x +/- 2i
The amount of sales tax is $17.50 because of trust.
Answer:
D.
Step-by-step explanation:
Add 2 to both sides:
Add half of the coefficient of the x, squared to both sides:
Simplify:
Complete the square:
![x-5=\sqrt[]{44}](https://tex.z-dn.net/?f=x-5%3D%5Csqrt%5B%5D%7B44%7D)
or ![x-5=-\sqrt[]{44}](https://tex.z-dn.net/?f=x-5%3D-%5Csqrt%5B%5D%7B44%7D)
or 
The axis which the point is reflected is vertical because for two different x-values, there is one y-value. In this case, you can tell that the vertical axis is x=0, which is basically the y-axis itself. To find the reflection point, find the average between the two x values.
(3+(-3))/2
0/2
0
This value 0 is the x-value of the vertical axis.
