Answer:

(2x -3)(2x -1)

Step-by-step explanation:

We have filled in the X-diagram so the side values have a product equal to the top value, and a sum equal to the bottom values (the middle term).

We're not sure how you've been taught to split the leading coefficient to arrive at the factors shown on the right.

4(x+6)≤−56 it says Solve the inequality.

vlabodo [156]

$\tt \: 4(x + 6) \leqslant - 56$

Divide both sides of the inequality by 4

$\sf \: x + 6 \leqslant - 14$

Move the constant to the right-hand side and change its sign

$\bf \: x \leqslant - 14 - 6$

Calculate the difference

$\rm \: x \leqslant - 20$

And we are done solving!!~

The cost in dollars of making x items is given by the function C(x) = 10x + 500. a. The fixed cost is determined when zero items

Brilliant_brown [7]

Answer:

a. $500

b. $250

Step-by-step explanation:

a. For zero items produced, cost will be-

$C(0) = 10(0) + 500 = 0 + 500 = 500$

b. For zero items produced, cost will be-

$C(25) = 10(25) + 500 = 250 + 500 = 750$

c. If $C(x)_{max} = 1500$

$10x + 500 = 1500\\10x = 1000\\x = 100$

∴ domain for cost function will be $[0,100]$ and range will be 100
