I would use a proportion:
336 miles/7 hours = x miles/15 hours (cross multiply)
x= 720 miles
A 5% discount indicates that her total purchase amount will be decreased by 5%. Paying full price could be shown as 1.00, so we must subtract 0.05 from the full price to represent the discounted total (1.00-0.05 = 0.95).
Only one choice, D, contains this multiplier so we can be certain of this answer.
Answer:
D) 2x^2 + 11x^3 + 12x^2 - 10x - 8
Step-by-step explanation:
you multiply each term of the first expression with each term of the second expression and add all the terms
so start with x^2 * 2x^2 = 2x^4
x^2 * 3x = 3x^3
x^2 * -4 = -4x^2
4x * 2x^2 = 8x^3
at this point it's clear that the correct answer is D but we can continue
4x * 3x = 12x^2
4x * -4 = -16x
4x^2
6x
-8
by adding
2x^2 + 11x^3 + 12x^2 - 10x - 8
Answer:
Hi, I think that it's both. Hope this helps!
Step-by-step explanation:
X comes first, then y....so ur points are (-5,3)
