Answer:
<em>D.) 6 </em>
Step-by-step explanation:
<em>-3+2*6=9</em>
Answer:
yes
Step-by-step explanation:
functions have one input for every output.
the input side has unique and individual numbers therefore it's a function.
Answer:
7y + 2x + 34 = 0
Step-by-step explanation:
The gradient for perpendicular, m = -2/7
The formular equation, y - y1 = m(x - x1)
The equation of line through (4, -6) is:
y - (-6) = -2/7(x - 4)
y + 6 = -2x/7 + 8/7
7y + 42 + 2x - 8 = 0
7y + 2x + 34 = 0
Vertex is at the point ( h , v )
The equation of a parabola is:
x = a ( y - v )² + h
Answer: B )
Step-by-step explanation:
By Law of Indices,
8^(-2) = 8^0 / 8^2
= 1 / 64.
