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.
Y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0)
We are told the slope is 4 so
y=4x+b, now using point (-7,-6) we can solve for the y-intercept...
-6=4(-7)+b
-6=-28+b
22=b so our line is:
y=4x+22
If the equation log(6x+10)=log(1/2) x is solved by graphing, the curves intersect at approximately x=0.46
Answer:
$170
20+15t
Step-by-step explanation:
she already makes $20 in a day and then you add the 10 times $15 in tips which makes 170.
for the equation, she makes 20 so you add it to 15 times t which is the hypothetical number of tables
