Answer:
Step-by-step explanation:
the slope of line n is also -3 as it is parallel to m
The answer is A
Answer:
Below in bold.
Step-by-step explanation:
A. −16x2 + 24x + 16 = 0
-8(2x2 - 3x - 2) = 0
-8(2x + 1 )(x - 2) = 0
x = -0.5, 2.
So the x-intercepts are (-0/5, 0) and (2, 0).
B. As the leading coefficients is negative (-16) the vertex of the graph will be a Maximum.
To find its coordinates we convert the function to vertex form:
f(x) = −16x2 + 24x + 16
= -16(x^2 - 1.5x) + 16
Completing the square on contents of the parentheses:
= -16 [(x - 0.75)^2 - 0.75^2] + 16
= -16(x - 0.75)^2 - 16 * -0.75^2 + 16
= -16(x - 0.75)^2 + 9 + 16
= -16(x - 0.75)^2 + 25.
So the coordinates of the vertex are (0.75, 25)

Answer:
23 friends
Step-by-step explanation:
Let the number of friends she has = x
Total number of gum = 47 pieces
She gave 2 each to her friends, hence:
2x + 1 = 47
2x = 47 - 1
2x = 46
x = 46/2
x = 23
Therefore, the number of friends she has is 23
