2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35
x=3
Answer:
y=(x-5)^2 - 6
Step-by-step explanation:
Subtracting the 5 to the x moves the parabola 5 units to the right. Putting the -6 at the end moves the parabola down 6 units.
The answer is 72

Answer:
140.42 US dollars
Step-by-step explanation:
250x1.3687=342.175
342.175-150=192.175
192.175/1.3687=~140.41
Answer:
y=2x-2
Step-by-step explanation:
find the slope (m)
m=y2-y1/x2-x1
m=4-(-2)/3-0
m=4+2/3-0
m=6/3
m=2
y-y1=m(x-x1)
y-(-2)=2(x-0)
y+2=2x
y=2x-2
