Answer:
Step-by-step explanation:
I'll help you just let me figure this out real quick, do you still want the answer?
I believe it would be 525 calories
120/15=8
8x25=525
Split it up an group with like ones (6x^3 with 2x since 6 and 2 are divisble by 2 and 9x^2 with 3 since both divisible by 3)
(6x^3+2x)+(9x^2+3)
undistribute using reverse distributive property (ab+ac=a(b+c))
2x(3x^2+1)+3(x^2+1)
undistribute again
(3x^2+1)(2x+3)
The generic equation for a linear function can be expressed in the slope intercept form f(x) = mx + b, where m is the slope and b is the y intercept. For this problem we can first find the equation of the line. Then we substitute x = 7 to get the f(x) value, which is n at the point x = 7.
To find the equation of the linear function we first find the slope. Slope is defined as the change in f(x) divided by the change in x. As we are given a linear function, the slope at every point is the same. We can pick any two points known to find the slope.
Let's pick (3, 7) and (9, 16). The slope m is m = (16-7)/(9-3) = 9/6 = 3/2.
Now that we have the slope, we can plug in the slope and one of the points to find b. Let's use the point (3, 7).
f(x) = mx + b
7 = (1/2)(3) + b
b = 11/2
Now we can write the equation
f(x) = (1/2)x + 11/2
Plugging in x = 7 we find that f(7) = 9. n = 9
The answer is 2.6. I could be wrong.
