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
X×$1.25=y
Step-by-step explanation:
they are buying x pounds of broccoli so the amount of broccoli times the amount it costs equals y
The answer is D, y - 4 = -2(x - 1).
Point Slope Form: y - y₁ = m(x - x₁)
Info Given:
Coordinates - (1,4)
Slope: -2
(1,4)
x₁ y₁
Plug slope and point into formula: y - 4 = -2(x -1)

Answer:
All real numbers are solutions!
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+4=9+5(x−1)
Step 1: Simplify both sides of the equation.
5x+4=9+5(x−1)
5x+4=9+(5)(x)+(5)(−1)(Distribute)
5x+4=9+5x+−5
5x+4=(5x)+(9+−5)(Combine Like Terms)
5x+4=5x+4
5x+4=5x+4
Step 2: Subtract 5x from both sides.
5x+4−5x=5x+4−5x
4=4
Step 3: Subtract 4 from both sides.
4−4=4−4
0=0
