Step-by-step explanation:
Explanation:
Because
(2,6) is in the function, we can plug
6 as y
and
2 as x.
From that we get
6=a(2−1)2+k
6=a+k
Same for the next point:
12=a(3−1)2+k
12=22a+k
12=4a+k
Now we have this system of equations to solve:
a+k=6
4a+k=12
Solving it leads to the conclusion that
a=2,k=4 .
Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
The equation is 2x+3y=1,470. Slope intercept form is y=mx+b. So we can convert it:
2x+3y=1470
3y=-2x+1470
<u>y=-2/3x+490</u>
It helps you get the correct answer
7(3-4)-3(-2+6)
21-28+6-18
-19
