Answer:
General Equation of a Line
Step-by-step explanation:
Find the slope first and then place the values on the general formula. The final step is to solve for y
Yes that’s completely true because of course you can’t say it is false
Answer:
y = 5/4x - 9
Step-by-step explanation:
y = mx + b
when you plot 4, -4 you have your first clue and point. then go up 5 and right 4 or down5 and left 4. When you go down you will reach the y intercept. On the number- 9. So -9 is your y intercept which goes in b.
Since 5/4 goes in the mx since it is slope the answer is y = 5/4 - 9
Group x terms
(2x^2+8x)-12=0
undistribute 2
2(x^2+4x)-12=0
take 1/2 of 4 and square it, add negative and positive of it insde (2^2=4)
2(x^2+4x+4-4)-12=0
factor perfect square
2((x+2)^2-4)-12=0
distribute
2(x+2)^2-8-12=0
2(x+2)^2-20=0
add 20 to both sides
2(x+2)^2=20
divide both sides by 2
(x+2)^2=10
sqrt both sides, remember to take positive and negative root
x+2=+/-√10
minus 2 both sides
x=-2+√10 and -2-√10
