Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)

Answer:
Option B, 8/5 hr
Step-by-step explanation:
1/2 + 1/8
1*4 / 2*4 + 1/8
4/8 + 1/8
5/8 = 1/t
5t / 5 = 8 / 5
t = 8/5
Answer: Option B, 8/5 hr
Answer:
C. y = 2x² +8x +6
Step-by-step explanation:
Reflecting f(x) across the y-axis changes the sign of x, so the new function is ...
f(-x)
Vertical scaling by a factor of "a" multiplies the function value by "a", so the new function is ...
a·f(x)
Doing both gives you ...
y = a·f(-x)
y = ax² +4ax +3a
None of the answer choices look like this. However, they match this if a=2:
y = 2x² +8x +6
