Answer:
Step-by-step explanation:
The roots are really just what x is when the equation is equal to zero. So, an equation with these roots would look like this:
(x+3)(x-4/5)=y
however, this is not standard form. To get standard form we will need to expand the equation using FOIL.
x^2+3x-4x/5-12/5=
x^2+11x/5-12/5
and that would be your answer.
This stuff is a bit tricky and it get annoying with those pesky fractions. If you have any questions just comment.

Q1
(16.75*1.065)*(1.15)=21.52. Tax comes before tip so has to be done in that order. Hope it helps.
Q2
C. is the correct answer. To work it out for yourself just work out what 10 percent is and then half that. IE. 5 percent and add the two figures together.
Q3
16.75*1.15*1.065
=20.5145625
=20.51
therefore, the closest answer is B
Q4
The sales tax rate is 7.25%.
Cost of messenger bag = $52.50
Kevin will pay sales tax = 7.25% of 52.50
= \frac{7.25}{100}\times 52.50
= 0.0725 × 52.50
= $3.80625 ≈ $3.81
Kevin will pay $3.81 sales tax on messenger bag
Q5
D. 20%
$15 x .2= $3
if you didn't have the options you could do
3/15=.2
Q6
x = (38.99) (.25) x = 9.75 Then; x = $38.99 - $9.75 x = $29.24 Bobbi needs to pay $29.24 for the shirt.
Q7
3.65 + 4.25 + (0.99 x 3) + 6.75 = 17.62
5.5% = 0.055
17.62 x 0.055 = 0.97
17.62 + 0.97 = 18.59
Q8
Shawn would leave $6.84 for a tip. Solution: 15% = 0.15 0.15 * $45.60 = $6.84
Q9
26.95 * x = 21.56
x = 21.56/26.95
x = 0.8
x = 80%
=> 100% - 80% = 20%
Q10
75................100%
(88.5-75)........x
x=(13.5*100):75
x=1350/75
x=18
Answer: 18%
Answer:
1/4

Step-by-step explanation:
Preston adopted a cat from a rescue shelter
He needs to buy food for his new cat so he compared the price of cat litter at different stores
Preston gets the best deal at fluffy felines pet shop
They sell 20 pound jug litter for $8.60
Therefore the cost of the cat litter per pound can be calculated as follows

= 0.43
Hence the cost of the cat litter per pound is $0.43
