Answer:
No
Step-by-step explanation:
Every x value in the domain should only have 1 y value. In the graph, for x=5 (the input) there are 2 y values (6 and -6) so this is not a function.
The ratios are equivalent because you multiplied 18:4 by 2&3. And also you divided it by 2. I had the same homework!
5. If a point is equidistant from the endpoints of a segment, then it must be the midpoint of the segment. True
6. The set of all points in the plane that are a given distance from a
line segment is a pair of lines parallel to the given segment. True
Answer:
x³ + 3x² - 16x + 12
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(x - 2) + 5x(x - 2) - 6(x - 2) ← distribute the 3 parenthesis
= x³ - 2x² + 5x² - 10x - 6x + 12 ← collect like terms
= x³ + 3x² - 16x + 12
Multiply the parenthesis by 6:
-7x+6x-492-2(x+3)+10
Multiply the parenthesis by -2:
-7x+6x-492-2x-6+10
Calculate the sum of similar terms:
-3x-492-6+10
Calculate the sum or difference:
-3x-488
