Answer:
5
Step-by-step explanation:
since -4 *-2 = 8 and -8+8=0
0*-2=0
0+5=5
Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
Answer:
7x^2+9x
Step-by-step explanation:
Hope this helps...
7x^2+(5x+4x)=
7x^2=9x
Answer:
y/x = R
Step-by-step explanation:
The two quantities x and y are proportional means they have a relation.
The equation is;
y= Rx ------to find the proportional R you make R the subject of the formula;
y/ x = R
