Answer:
f = 2x + 24/ 3
Step-by-step explanation:
Step 1: Divide both sides by x.
fx/x = 2/3 x^2 + 8x/x
f = 2x + 24/3
That is just absolute value, basically what it means is take off whatever sign there was attached to it (such as a negative sign)
The correct answer is true since an integer is simply just a number
Answer: y = 7.5
Step-by-step explanation:
Suppose that y varies directly with x
That is, y∝x
Convert y∝x to a full equation by introducing a constant k to the right hand side.
Therefore, y = kx
Given that y = 10 and x = 20
Substitute y and x in the equation above. We have;
10 = k(20)
10 = 20k
20k = 10
k = 10/20
k = 0.5
Since k = 0.5, the equation y = kx becomes y = 0.5x
Now, to find y if x = 15, substitute x in equation y = 0.5x
Therefore, y = 0.5(15)
y = 7.5
10 calories i believe because if you divide 100 divided by 10 that will equal 10
