Answer:

f(x) = x² + 9x - 22

Step-by-step explanation:

Given that x = 2 and x = - 11 are zeros, then

(x - 2) and (x + 11) are factors

and f(x) equals the product of the factors

f(x) = (x - 2)(x + 11) ← expand factors

f(x) = x² + 9x - 22 ← is a possible function

What’s three points that satisfy the system of inequality’s of 4x+6y&lt;24
Vlada [557]

Answer:

(0,0), (1,1), (2,2)

Step-by-step explanation:

When testing to find possible points in situations like this, I always start by testing with the origin point (0,0).

In this case:

4x+6y<24 ==> 0 + 0 < 24  TRUE, it satisfies the inequality.

We then try with (1,1):

4x+6y<24 ==> 4 + 6 < 24  TRUE, it satisfies the inequality.

And with (2,2):

4x+6y<24 ==> 8 + 12 < 24  TRUE, it satisfies the inequality.

First, we must convert the total miles into kilometers. If there are 1.609 kilometers in one mile, then 26.219 miles equals 42.3 kilometers. We then divide by the total minutes (128) to get the speed in kilometers per minute which should be 0.32 or 0.3 kilometers per minute.
