Answer:

2

Step-by-step explanation:

Linear equation form:  y = mx + b

(where m is the slope and b is the y-intercept)

The rate of change for a line is the slope.

Function 1:  y = 6

⇒ the slope is zero so the rate of change is zero

Function 2:  y = 2x + 7

⇒ the slope is 2 so the rate of change is 2

Therefore, 2 - 0 = 2

So the rate of change of function 2 is 2 more than the rate of change of function 1

Please answer the question that is in the photo attached below

Answer:

\huge\boxed{b=\sqrt{7}}

Step-by-step explanation:

In order to solve for this equation we have to note a couple of things.

There is a diagonal square inside a larger square. The space formed by the smaller square not being in the larger square is a right triangle.

The side length of the smaller square (4) is also the hypotenuse of this triangle.

Since we know that the other side length of the triangle is 3, we can use the Pythagorean Theorem to find the value of b.

The Pythagorean Theorem states that a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.

We can substitute 3 in as a and 4 in as c and find b.

3^2 + b^2 = 4^2

9+b^2=16

b^2=7

b = \sqrt{7}

So b is \sqrt{7} units long.

Hope this helped!

I need help plz, only if you now the answer

Answer:

{-2, 1, 2}

Step-by-step explanation:

F(x) = x³ - x² - 4x + 4 is factorable as follows:

F(x) = x²(x - 1) - 4(x - 1).  (x - 1) is a common factor.  Factor it out:

F(x) = (x - 1)(x² - 4)

x² - 4 can be factored further:

F(x) = (x - 1)(x - 2)(x + 2)

The possible roots of F(x) are {-2, 1, 2}.
