20+36= 56
56+20=76
she drank 76 ounces
and there are 8 ounces in a cup
76÷8=9.5
she drank 9.5 cups
1) Since order does not matter, 10C5 = 252.
2) I don't think I understand the 2nd question, can you elaborate.
Answer:
g(x) is red and f(x) is blue. f(x) has been moved three units down the y-axis.
Answer:
0
Step-by-step explanation:
calculate the change in y over the change in x. m=y2-y1/x2-x1
Answer:
4x² + 13x + 3 and 2x² - 3x - 17
Step-by-step explanation:
(a)
f(x) + g(x)
= 3x² + 5x - 7 + x² + 8x + 10 ← collect like terms
= 4x² + 13x + 3
(b)
f(x) - g(x)
= 3x² + 5x - 7 - (x² + 8x + 10)
= 3x² + 5x - 7 - x² - 8x - 10 ← collect like terms
= 2x² - 3x - 17
