Answer:
7. C
8. D
Step-by-step explanation:
7. The interest rate is 8% or .08. You find that by solving I=Prt (interest=original amount*rate*time in years)
8. The discounted price would be $48 (80*(1-.40)) Then you multiply that 48 by .08 and add that amount to the $48.
Answer: Algebraically, linear functions are polynomial functions with a highest exponent of one, exponential functions have a variable in the exponent, and quadratic functions are polynomial functions with a highest exponent of two.
Step-by-step explanation: A linear equation is a type of equation in which the graph is straight and each term is a constant or a power of a constant. The formula is y=mx+b. Quadratic equations are similar to exponential equations by having a curve in the graph.
Well the centroid is the point that connects the median of a side with the opposite vertex. This means that each line is split i half. Notice that line HG is split in half by point K. that means that each of the segments that K splits is equal. so we know
HK = KG
and we know
HK = 3x
KG = x + 8
since
HK = KG then
3x = x + 8
2x = 8
x = 4
now we have x. we know that the each line that runs from a midpoint to a vertex is seperated by the centroid. the 2 line segments are a 2:1 ratio. so
2*JL = 1LG
we know
JL = x + 3
so
2 * (4 + 3) = LG
LG = 14
The first one I think because a linear function is always going to have a constant rate of change in one direction going straight up
This problem is tough until you clean it up so you can see what's going on.
On the left side, (7 + 5 - 3) = 9 . So the left side is x + 9 .
On the right side, (16 - 8) = 8.
So the equation is really <u>x + 9 = 8</u>
Subtract 9 from each side: <em> x = -1</em>
