Which of the following is a solution of 4x + 2y ≤ 6?

cestrela7 [59]

Answer:

D. (1,0)

Step-by-step explanation:

Just plug in each coordinate for x and y into 4x+2y and see which one is less than or equal to 6.

Lets go through all of the possible answers:

A. (0,4)

4(0) + 2(4) ≤ 6

0 + 8 ≤ 6

8 ≤ 6

This is false. 8 is not less than or equal to 6.

B. (5,0)

4(5) + 2(0) ≤ 6

20 + 0 ≤ 6

20 ≤ 6

This is false. 20 is not less than or equal to 6.

C. (5,7)

4(5) + 2(7) ≤ 6

20 + 14 ≤ 6

34 ≤ 6

This is false because 35 is not less than or equal to 6

D. (1,0)

4(1) + 2(0) ≤ 6

4 + 0 ≤ 6

4 ≤ 6

This is true, because 4 is less than 6.

Let f(x)=4-x^2, find ( f(x+h)-f(x) ) / h and simplify

Alja [10]

If $f(x)=4-x^2$ , then

$f(x+h)=4-(x+h)^2=4-(x^2+2xh+h^2)=4-x^2-2xh-h^2$

$\dfrac{f(x+h)-f(x)}h=\dfrac{(4-x^2-2xh-h^2)-(4-x^2)}h=-\dfrac{2xh+h^2}h$

Then for $h\neq0$ , we can cancel common terms:

$\dfrac{f(x+h)-f(x)}h=-2x+h$
