Solve x 2 + 9x + 8 = 0 by completing the square. What are the solutions?

vivado [14]

x^2+9x+8=0

(x+1)(x+8)=0

x+1=0

x=-1

x+8 = 0

x=-8

solutions are -1 and -8

What is the solution for the system of equations? Use the substitution method to solve.

Paraphin [41]

Y = 5 - 3x....so sub in 5 - 3x for y in the other equation

5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1

now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2

check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)

so ur solution is (1,2)
