Answer:

f(-4) = 72, f(x + 5) = 3x² + 23x + 36

Step-by-step explanation:

f(-4) = 3(-4)² - 7(-4) - 4

= 48 - (-28) - 4

f(-4) = 72

f(x + 5) = 3(x + 5)² - 7(x + 5) - 4

= 3(x + 5)(x + 5) - 7(x + 5) - 4

= 3(x² + 10x + 25) - 7(x + 5) - 4

= 3x² + 30x + 75 - 7x - 35 - 4

f(x + 5) = 3x² + 23x + 36

| 5x -2y | - | 3x | if x = -3 and y = 2

Natalka [10]

Answer:

If $x = -3$ and $y = 2$ , then $|5x-2y|-|3x| = 10$

Step-by-step explanation:

This is a problem that utilizes both substitution and the order of operations.

$|5x-2y|-|3x| = \\|-15-(2)(2)|-|(3)(-3)| =\\ |-15-4|-|(3)(-3)| =\\|-19|-|(3)(-3)| =\\19-|(3)(-3)| =\\19-|-9| =\\19-9 =\\10$

Jenny makes food for her hummingbird feeders. The food is made up of 1 part sugar and 4 parts water. She uses 3434 cup of sugar

Bond [772]

Okay so every part of sugar requires 4 parts of water

so

3434 cups of sugar x 4 (parts of water per 1 part of sugar) = 13736

She will need to use 13, 736 parts of water for 3, 434 parts of sugar
