Y = -(-2)^2 + 4(-2) + 1
y = -4 - 8 + 1
y = -11
The set of equations best models the point of intersection of the arrow and the target is:
y = –0.008x² + 0.2x + 7 and y = 0.12x.
<h3>What are the equations of the point of intersection?</h3>
To find the equations, we have to look at two things.
- The coordinates of the point.
- The behavior of the arrows trajectory, that is, if it's concave up or concave down.
The coordinates of the point are (35, 4.2), hence the best linear representation is:
y = 0.12x.
This leaves the first two options. The trajectory is concave down, which removes the second option, hence the correct option is:
y = –0.008x² + 0.2x + 7 and y = 0.12x.

First convert them to fractions (the answer choices are fractions):
a) 0.333... = 1/3
b) 0.555... = 5/9
Now add a and b:
1/3 (or 3/9 for a common denominator) + 5/9 = 8/9
That fraction is in simplest form, so leave it as it is.
Hope this helps!
X + y = 30
3x = 2y
y = 30 - x
3x = 2(30 - x)
3x = 60 - 2x
5x = 60
x = 12
12 + 18 = 30
Answer:
I'm pretty sure it's 1 cup of water
You need 2 cups of pancake mix more than water so if you have 3 cups of pancake mix then you'd need 1 cup of water.
6 cups of mix = 4 cups of water
the cups of the mix is are 2 more cups than the water
3 cups of mix = 1 cup of water
I hope that helps and good luck! :)
