Gruop x terms
(x²-8x)+3=0
take 1/2 of linear coefient and square it
-8/2=-4, (-4)^2=16
add negative and positive inside
(x²-8x+16-16)+3=0
factor perfect square
((x-4)²-16)+3=0
expand
(x-4)²-16+3=0
(x-4)²-13=0
add 13 both sides
(x-4)²=13
answer is C
If that is 54.300 the greatest whole number would be 54 if it is supposed to be 54,300 then it would stay the same and be 54,300
Answer:
x =7/ 3
Step-by-step explanation:
5x+ 22= 2x+ 29
⇔5x - 2x= 29 - 22
⇔3x = 7
⇔x = 7/3
Answer:
=21x2−13x+8
Step-by-step explanation:
=3x(7x−4)+−1(x−8)
=3x(7x−4)+−1x+(−1)(−8)
=3x(7x−4)+−x+8
Distribute:
=(3x)(7x)+(3x)(−4)+−x+8
=21x2+−12x+−x+8
Combine Like Terms:
=21x2+−12x+−x+8
=(21x2)+(−12x+−x)+(8)
=21x2+−13x+8
Answer:
(1, - 1)
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
The lines intersect at (1, - 1)
Then (1, - 1 ) is the solution to the system.
