Answer:
(x + 2) (x + 3) = x² + 3x + 2x + 6 = 12 (multiply the binomials)
(x + 2) (x + 3) = x² + 5x + 6 = 12
(x + 2) (x + 3) = x² + 5x + 6-12 = 0 (add the like term and bring the positive 12 to the other side which makes it negative)
x² + 5x + 6 = 0
Using the snowflake method - (finding the factors of 6 that adds/subtracts to give you 5).
This method will give you the factors (x + 6)(x - 1)
ZERO PROPERTY RULE:
(x + 6) = 0
x = -6
(x - 1) = 0
x = 1
The two solutions to the equation are -6 and 1.
0.000000001=0.1
0.000000001=10^9
0.000000001=10^9x10^9=01
0.000000001=10^-9 =0.1
=10^-9 x 0.1
Answer:
A, D, and E
Step-by-step explanation:
80% off 22 is 17.6
A- 80 ? 100=0.8 x 22= 17.6
D- 0.8 x 22= 17.6
E- 4/5=0.8 x 22= 17.6
Answer:
y=4x+9
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-(-11))/(-2-(-5))
m=(1+11)/(-2+5)
m=12/3
m=4
y-y1=m(x-x1)
y-(-11)=4(x-(-5))
y+11=4(x+5)
y=4x+20-11
y=4x+9
Answer:
y=7, x=5
Step-by-step explanation: hope this helps
