Answer:
Yes. Juan will break even because 16 and -16 are a zero pair. -16 is the additive inverse of 16. So the sum will be 0.
Answer:
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height.
Step-by-step explanation:
Answer:
y = x^2 - 4
Step-by-step explanation:
The vertex of a parabola is exactly halfway between the focus and the directrix. If the focus is at (0, -6) and the directrix is the line y = -2, then we do this to locate the vertex: Draw a vertical line through (0, -6) also crossing the line y = -2. The y value halfway between y = -6 and y = -2 is y = -4, and the vertex is thus (0, -4).
Using the vertex method, write out the equation of this parabola, starting with the general form y - k = (x-h)^2, where (h, k) is the vertex. Here h = 0 and k = -4
We get: y + 4 = (x - 0)^2, or y + 4 = x^2, or y = x^2 - 4. As a check, let x = 0; y = -4, which is the y-coordinate of the vertex.

a). The equation is
Balance in my account = 12.5 m + 100 .
The graph is a straight line with slope = 12.5 and y-intercept = 100.
'm' is the number of months after you start this savings plan.
b). The part of the Real Estate ad that tells us the cost of land on Mars is cut off.
However much 10 acres will cost, put that number into the equation where it
says "Balance in my account", and solve the equation for 'm'.
25).
a). It's easy to find four points. Just let 'n' be 3, 4, 5, and 6, and for each one,
use the formula to calculate what 'S' is. Yes, if you plot them, they'll all fall in
a straight line.
b). No. The value n = 3.5 does not make sense in the context of the problem.
We're talking about polygons with 'n' sides, and it's very hard to draw or imagine
a polygon with 3.5 sides.
