We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.

This gives

f'(x) = 7

Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.

2x + 7 as the you use the power rule to find the derivative of x^2 and 7x, since -4 is a constant the derivative of it would be 0

A triangle has two sides that measures 7 cm which of the following cannot be the measure of the third side

klasskru [66]

Any side that is greater than 7 + 7 = 14 will not make a triangle.

x > 14 will not create a triangle.

the side length of the state flag of Colorado are in the ratio of 2:3 if the flag is 12 ft long what is the height?

yanalaym [24]

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

$\frac{2}{3} = \frac{x}{12}$

Now isolate x (in order to solve for it)

$12 * \frac{2}{3} = \frac{x}{12}*12\\8 = x$

x= 8

The height is 8.

8/12 = 2/3 ✅

Please help I’ll mark brainliest as long as you tell me how you got that answer, also I apologize if it’s kinda blurry. I hope y

Answer:

Step-by-step explanation:

Not another one! ;)

A can be eliminated because the numbers don‘t match. B seems like a possible answer, let’s first check the others out. C and D can be slim instead because the variable, g, should be next to the 1.5 and 2.5. C and D both change the variable location. So, B.
