Solve for x over the real numbers using factor method:
10 x^2 + 19 x - 15 = 0
The left hand side factors into a product with two terms:
(2 x + 5) (5 x - 3) = 0
Split into two equations:
2 x + 5 = 0 or 5 x - 3 = 0
Subtract 5 from both sides:
2 x = -5 or 5 x - 3 = 0
Divide both sides by 2:
x = -5/2 or 5 x - 3 = 0
Add 3 to both sides:
x = -5/2 or 5 x = 3
Divide both sides by 5:
Answer: x = -5/2 or x = 3/5
It's helpful to find 10%, as it is on a smaller scale and easier to find. From there it's simple to just multiply by 10 to get 100% of her earnings.

Answer:
y is 1/3 less than x
Step-by-step explanation:
No need to Apologize my friend!! thats what we do here, ask all the questions you want. If you just compare the x part of the coordinate, to the y part of the coordinate, the answers obvious. for example, the first labeled point is (1 and 2/3, 1 and 1/3) the y part is 1/3 less than the x part. so y is 1/3 less than x
Answer:
108.505
Step-by-step explanation:
Let's talk money for just a second. Which would you rather have 20 dollars or 20.32 20dollars and 32 cents?
Isn't 20.32 bigger than 20.
You should say yes.
If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.
Answer:
D
Step-by-step explanation:
There are 9 letters, which contains 2Qs, 3Ls and 4Bs.
If the 9 letters are distinct, the number of permutations they have will be 9!.
! is the factorial sign.
9! = 9*8*7*6*5*4*3*2*1
HOWEVER, we have some identical elements, so we need to get rid of the permutations of the same letters.
Thus we have:
The answer is D
