Answer:
x= -1/2 and x=2/11
Step-by-step explanation:
Write the 7x as a difference. It'll make it easier to factor out. An example of this would be 11x-4x
Therefore, the equation would look like this: 22x^2 + 11x-4x -2 =0
Look at it as if there are two equations: 22x^2+11x and -4x-2
Factor out the greatest common factor, which is 11 from the first equation. The equation will then look like this: 11x(2x+1)
Take the GCF for the second equation as well (which is -2). The equation should then also look like this: (2x+1)
Use the numbers on the outside of each of the parenthesis to form its own equation (to factor it out). This will be 11x-2
Now we have factored! Since the parenthesis equations are the same, we know that that is also part of the equation, so:
(11x-2)(2x+1)
Solve each equation for x by equaling them both to zero
The original price of the item is said to be 100 dollars.
Now, it offers 15% discount. Let's solve for the dicounted price.
=> 15% = 0.15
Solution:
=> 300 * .15
=> 45 dollars
=> 300 dollars - 45
=> 255 dollars
I think you need to retype this one. The formatting makes this question difficult to understand.
Answer:
(-2,-1)
Step-by-step explanation:
y=2x+3
y=3x+5
so y=y
then:
2x+3=3x+5
3-5= 3x-2x
-2= X
x=-2
Answer:
6%
Step-by-step explanation:
<em>To solve this you need to subtract 607000 by 572000 to see how many people in the population decreased.</em>
607,000- 572,000= 35,000
Then you put 35,000 over 607,000
also you need x over 100
35000/607,000 x/100
Then do cross product property
35,000*100=3,500,000
607,000* x= 607,000x
3,500,000= 607,000x
Then do 3,500,000 divided by 607,000
You get 5.76%
Round to the nearest percent and get 6%
