Answer:
4
Step-by-step explanation:
Since it costs $3.75 for every earring, multiply e by 3.75 like this: 3.75e
Add 9.5 on top of that since Dani already bought the necklace for $9.50
3.75e + 9.5
This sum has to be less than or equal to 25 because the budget is $25
3.75e + 9.5 ≤ 25
To find e subtract 9.5 from both sides
3.75e + 9.5 ≤ 25
- 9.5 - 9.5
3.75e ≤ 15.5
Divide both sides by 3.75
3.75e/3.75 = 15.5/3.75 = 4.133...
You can't buy 0.133 of an earring, so the max amount of earrings she can buy is 4.
Answer:
y ≤-1/2 x-1
y < -4x+25
Step-by-step explanation:
The y intercept is -1
The slope is negative since the line goes down from left to right
The line is y = -1/2 x -1
The line is solid so there is an equals in the inequality
The graph is shaded below the line
y ≤-1/2 x-1
Question 5
The y intercept is 25
The slope is negative since the line goes down from left to right
The slope is (y2-y1)/ (x2-x1) = (49-25)/(-6-0) = 24/-6 = -4
The line is y = -4 x +25
The line is dotted so there is NOT an equals in the inequality
The graph is shaded below the line
y < -4x+25
1 3/4 × 4 = 7/4 × 4 = 7 hours on saturdays
3/4 × 3 = 9/4 = 2 1/4 hours on Wednesdays
7 + 2 1/4 = 9 1/4 hours of volunteering total
It is B
-2 / 5 + 12/5 = 10/5 = 2
