22x^2+7x-10 = x+5

2x^2+7x-15

y2x^2+6x-15


Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.


With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)

A prism is completely filled with 1120 cubes that have edge lengths of 1/2 in. What is the volume of the prism?
DedPeter [7]

Answer:

Volume of the prism = 140 cubic inches.

Step-by-step explanation:

The edge length of the cube is 1/2 inches.

The volume of the cube is given by

\text{Volume}=(\text{edge})^3\\\\V=(1/2)^3\\\\V=0.125

Now, it has been given that there are 1120 cube is completely filled in the prism. Hence, we have to the multiply the volume by 1120.

Volume of the prism = 1120 × 0.125

Volume of the prism = 140 cubic inches.

Expand the fraction 72/125 .so that it has a denominator of 1000.
Dmitrij [34]
X/1000=72/125  multiply both sides by 1000

x=72000/125

x=576

So the fraction is 576/1000

HELP ASAP!!!!<br> Does someone mind walking me through this. I really need help.
Tamiku [17]
The minimum of this graph is the focus of the parabola. I'm not sure with the maximum though but I think it doesn't have a maximum because the y value of the parabola will extend infinitely upward.

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers, (k), she can drive with 12
solong [7]
99 km ... 9 liters
x km   ... 12 liters

If the relationship is proportional, we have

\frac{99}{x} = \frac{9}{12}

from where 

x =  \frac{99*12}{9}= \frac{1188}{9}=\bold{132}

The answer is 132 kilometers.
