Answer:
0.3125
Step-by-step explanation:
Answer:
- 18x + 15y ≤ 300
- x ≥ 0; y ≥ 6
Step-by-step explanation:
Variables are defined in the problem statement.
18x +15y ≤ 300 . . . . total budget
y ≥ 6 . . . . . . . . . . . . minimum number of annuals
x ≥ 0 . . . . . number of perennials cannot be negative
This system of inequalities describes the situation.
7+3t -t
------- = ----- is the relevant equation here. We don't ask, "What is 7+3t over
4 8 -t over 8," but rather "Solve the following equation for t."
Cross multiplying, 56 + 24t = -4t
-56
Then: 28t = 56, and t = ------ = -2 (answer)
28
The solution to "<span>What is 7+3t over 4 = -t over 8" is t = -2.</span>
Answer:
x = -1 or x = -11
Step-by-step explanation:
f(x)= 2|x+6|-4
2|x+6|-4 = 6
2|x+6| = 6+4
2|x+6|=10
|x+6| = 10/2
|x+6| = 5
x+6 = ±5
x = ±5 - 6
x = -1 or x = -11
