Answer: about 14% of the 7 grade don't play sports
Step-by-step explanation: i think
For this, I will be factoring by grouping to solve for y.
Firstly, factor y^3 + 5y^2 and -9y - 45 separately, Make sure that they have the same quantity on the inside:
Now you can rewrite it as . However we are not finished factoring.
Now with y^2 - 9, we will apply the difference of squares rule, which is . Apply it as such:
Now that it is completely factored, we can apply the Zero Product Property and solve for y:
<u>In short, y = -5, -3, and 3.</u>
Its c the answer is c because 8+4 is 12 and if you get rid of the angle and move the line so it’s straight it would be both 8 and 4
Answer:
Bottom left
Step-by-step explanation:
A function cannot have more than one y value for any x value, hold a piece of paper up as a vertical line test. If the line on the graph intersects your vertical line more than once, it is not a function.
<span>c = w*45/13 + 60/13
I will be assuming that the equation will be linear since there are only 2 data points available. The form of the equation will be
c = aw + b
where
c = calories burned
a = some constant
w = weight
b = some other constant.
If you look at the equation, you'll notice that it looks like the equation for a line i slope intercept form. So first, let's calculate the slope of the desired equation.
a = (600-420)/(172-120) = 180/52 = 45/13 = 3.461538462
Now we have the equation
c = w*45/13 + b
Substitute the values for a known point, giving
420 = 120*45/13 + b
Now solve for b
420 = 120*45/13 + b
420 = 5400/13 + b
420 - 5400/13 = b
5460/13 - 5400/13 = b
60/13 = b
So now the equation is
c = w*45/13 + 60/13</span>
