Solve each inequality. Graph the solution on a number line.

Kamila [148]

Step-by-step explanation:

Step 1: Find the solution for the first one

$4x > -36$

$4x / 4 > -36 / 4$

$x > -9$ ← Solution

Step 2: Find the solution for the second one

$7u\le-49$

$7y/7\le-49/7$

$y \le -7$ ← Solution

Step 3: Find the solution for the third one

$-5m \ge 15$

$-5m / -5 \ge 15 / -5$

$m \le -3$ ← Solution

Step 4: Find the solution for the fourth one

$-2p > -3$

$-2p / -2 > -3 / -2$

$p < 1.5$ ← Solution

Step 5: Find the solution for the fifth one

$45 \le - 10r$

$45 / -10 \le -10r / -10$

$-4.5 \ge r$ ← Solution

Step 6: Find the solution for the sixth one

$-66 \ge -11t$

$-66 / -11 \ge -11t / -11$

$6 \le t$ ← Solution

The director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good pre

vova2212 [387]

Given:
Profit = 17,500
advertising dollar = 1,020

regression line:

Profit = 372.60 + 17.2(advertising dollar)
17,500 = 372.60 + 17.2(1020)
17,500 = 372.60 + 17,544
17,500 = 17,916.60

There is a residual value of 416.60.

17,916.60 - 17,500 = 416.60
