Answer:
x- axis. co-ordinate
Step-by-step explanation:
First thing to remember is that they were currently in week 0, when they began saving:The equation for Alex would look like: y=20x + 125 See that we are on week 0, and x is our weeks, and the equation would look like: y=20(0) + 125 Simplifying the equation, it will give us which it is y = 125That means that the first one is E. 125For the second, it shows our week 0, which is at 100.That means that the second one is I. 100
Move constant to the right-hand side and change its sign
2x^2 + 8 = -2 + 7
-2 + 7 = 5
Divide both sides of the equation by
x^2 + 4x = 5/2
Add (4/2^2) to both sides of the equation
x^2 + 4x + (4/2)^2 = 5/2 + (4/2)^2
factor the expression
(x + 4/2)^2 = 13/2
reduce the fraction by 2
(x + 2)^2 = 13/2
now solve equation for x
