M to the power 4 squared minus 23
For this case you have the following advantages:
1) you can see the graph of both equations
2) you can see where the equations intersect
3) the point of intersection represents the solution to the system of equations.
4) You can solve the problem in much less time than doing it by hand
5) You can find very accurate solutions.
Answer:
Step-by-step explanation:
<u>Standard form of quadratic function:</u>
<u>Vertex form:</u>
<u>Convert the given function by completing a square:</u>
y = x² - 8x - 3 =
x² - 2*4*x + 4² - 4² - 3 =
(x - 4)² - 19
Answer:
1. So $7 per hour
For 24 hour =7×24= $168
28-24=4
4×7=28
168+28=$196
or
For 28 hour
7×28
= $196
2. 7×112
=$784
3. To find the difference subtract
784-196=$588
To find slope use the formula rise over run. Rise up from 0 to 16 then run from 0 to 2 to get rise of 16 and run of 2 (16/2). Simplify the fraction 16/2=8 (like a regular division problem) and that give you your slope. The y-intercept is 0 because the line touches the y axis (the vertical axis) at 0 :)
