Answer:
The vertex is (-1, 4)
Not sure what the table looks like, but just plug the x values into the equation to get a complete point
Graph the points on a graph
Step-by-step explanation:
Answer:
-2/3
Step-by-step explanation:
rate of change is slope
so rearrange the equation to get in y = mx + b format
2x + 3y = 6
move the 2x over by subtraction
3y = -2x + 6
now divide by 3 to get y by itself
y = -2/3x + 2
Her average now is 88.
She needs to bring it up to a 90.
Let's start with if she gets a 90.
88 + 90 = 178
178/2 = 89
A 90 would only get her an average of 89, so you need to go higher.
88 + 91 = 179
179/2 = 89.5
88 + 92 = 180
180/2 = 90
She must get at least a 92 to get an average of 90.
