Vertex form 1/2(0), where 0 replaces x as a number the variable x is.
The vertex is (0,0).
Answer:
3 inches up per foot across
Step-by-step explanation:
rate of change = difference of y / difference of x
R = (18 - 12) / ( 6-4) = 6 / 2 = 3 inch / foot
Answer: The value is -6
Step-by-step explanation:
4 - 7(-2) = 18
18 + 5 = 23, so that is correct
If x = -2, then 3(-2) is -6
Answer: 64 %
Step-by-step explanation:
Assume attendance last year to be equal to "x"
- An increase in percentage sees us add the percentage amount to 100.
- A decrease in percentage sees us subtract the percentage amount from 100.
Projected attendance = ((100+25)/100) * x = 1.25x
Actual attendance = ((100-20)/100) * x = 0.80x
Hence ratio of a actual to projected attendance = 0.80x/1.25x = 0.64
Convert into percentage = 0.64 * 100 = 64 %
we have the following system of equations

we know that
The intersection of both graphs is the solution of the system of equations
using a graph tool
see the attached figure
the solution is the point 
therefore
<u>the answer is</u>
the solution of the system of equations is the point
