Answer:
16=D
17=A
18=A
19=B
20=D
Step-by-step explanation:
Put into slope intercept form, y=mx+b where m=slope
p=-2q+6
slope is -2
subsitute values for q and get values for p
q=0, p=6
(q,p)
(0,6)
(1,4)
p=q+4
slope is 1
subsitutte
q=0,p=4
(q,p)
(0,4)
(1,5)
below are the graphs
Answer:
Step-by-step explanation:
Rewrite X^2+22x=31, leaving space after the "22x:"
X^2+22x = 31
The coefficient of x is 22. Take half of that, obtaining 11.
Square this result: 11^2 = 121.
Write in "+121 -121" after the x term:
X^2+22x + 121 - 121 = 31
Rewrite X^2+22x + 121 as
(x + 11)^2 -121 = 31
Add 121 to both sides:
(x + 11)^2 = 152
Take the square root of both sides:
x + 11 = ±√152 = ±2√38
Finally, x = -11 ±2√38.
This is "solution by completing the square"
