The rectangles are similar. The difference between 7 and 8 is that the second one is dilated by 1/2
Rate is 60 mph
distance = speed x time
d = 60h
Answer is B
Find the x-intercepts by setting the function equal to 0
0 = 2x^2 - 3x - 2
Factor
2x^2 - 4x + x - 2 = 0
2x(x - 2) + 1(x - 2) = 0
(x - 2)(2x + 1) = 0
x - 2 = 0
x = 2
2x + 1 = 0
2x = -1
x = -1/2
the x-intercepts are at x = -1/2 & 2
Answer:
To add or subtract some rational numbers, you have to change the rational numbers so they have a common denominator. When you have a common denominator, you can then go on with the addition or subtraction on the numerator part.
Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
