Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula
. In this case, m is the rate of change, time is x, and the carrots remaining is y.
![m = \frac{118-136}{8-6} = \frac{-18}{2} = -9](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B118-136%7D%7B8-6%7D%20%20%3D%20%5Cfrac%7B-18%7D%7B2%7D%20%3D%20-9)
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.
Answer:
x = -0.5 or x = 2
Step-by-step explanation:
Finding solutions graphically is often easier if the equation can be put in the form f(x) = 0. Here, we can do that by subtracting the right-side expression to give ...
(-2x^2 +2) -(-3x) = 0
This could be put in standard form, but there is no need. A graphing calculator can deal with this directly.
The solutions are x = -0.5 and x = 2.
Answer:
7/8 ≈ .9
y = -3x/4 + 4.75
x = 9 ⅓
Rotation
Step-by-step explanation:
1.) 7/8 = 0.875 The hundredths place is 7, which means we round up to 0.9
2.) Isolate the y on the left. Then divide both sides by 4
3.) Subtract 7 from both sides, then divide both sides by 3
Rotation turns around a point Reflection flips across a line.
Answer: a^2x^2+9x^2+13x+6a
Step-by-step explanation:
(a^2+9) x^2+ 13x +6a
x^2(a^2+9)+13x+6a
Expand:x^2(a^2+9): a^2 x^2+9^2
x^2 a^2 +x^2*9
a^2 x^2+9x^2
a^2 x^2+9x^2+13x+6a
