Answer:
x=9.717
y=18.275
Step-by-step explanation:
First solve for x and then use x to help you solve for y
Answer:
f(x) = -4/3x² -2/3x +10
Step-by-step explanation:
The quadratic regression function of a graphing calculator or spreadsheet can determine the equation for you.
___
Or, you can determine it yourself.
The equation can be written in the form ...
f(x) = a(x +3)(x -5/2) . . . . . . . using the given x-intercepts
for some value of "a"
For x = 0, this must match the y-intercept.
f(0) = a(0 +3)(0 -5/2) = 10
-15/2·a = 10
a = -20/15 = -4/3
So, the function can be written as ...
f(x) = (-4/3)(x +3)(x -5/2)
or
f(x) = -4/3x² -2/3x +10
To the nearest whole number it would be 35
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
7+(-1)= 6
6/3 = 2
There are no other solutions I can find to it. It says sum but technically you can add a negative number.
Don´t listen to me if you think that I am wrong. But I hope this helps!!
