Answer:
Step-by-step explanation:
To put the equation into vertex form, we need to complete the square

This is in the form

So, the vertex is (2, -5)
and 
Answer:
slope of CE is 2/3
Step-by-step explanation:
used the slope formula: change in y-values / change in x-values
Simple interest formula:
I=PRT
I(interest money created in dollars)
P(initial amount of money)
R(interest rate as a decimal)
T(time in years)
I=7000(.07)(6)
I=$2,940
Therefore, the future value of A is $2,940
You can take the first point as the origin O(0,0) and the second one (-2,0.5) for easier calculations.
Find the slope, m = (y2 - y1)/(x2 - x1)
= -2-0 / -0.5-0 = 2/0.5 = 4
now take (x,y) = (0,0) and m= 4
use the point slope form
(y - y1) = m(x - x1)
(y - 0) = (4)(x - 0) ......taking (x1,y1) = (0,0)
y = 4x + 0 ...... in the form of y = mx + b

-23 is a negative number so that means 7 is a greater number. any number with a minus sign like this - means it’s a negative number, so any number that you have to compare it to and if that number has nothing before or after it, then that would be the greater number
