I solved on a calculator
Answer:
24h+168>288
Step-by-step explanation:
You want to sell <u>more than</u> 288 glasses, so you can start by writing 288 as less than a blank space.
Next, you know they sell 24 glasses and hour, so you can write that as 24h.
Finally, you know they have already sold 168 glasses. This is a constant and is added to the 24h.
The above inequality represents the number of hours they need to stay open to reach their goal.
Answer:
y = -2x + 3
y = -1/2x + 5
Step-by-step explanation:
- So the best way to solve is to come up with two slopes, I'd prefer 2 perpendicular slopes because perpendicular lines only cross once hence one solution guaranteed
- so say we choose a slopeA = 2 and slopeB = -1/2, the slopes are perpendicular only if when you multiply them you get -1
- then we use the slope intercept form of an equation y = mx + b
- we make up two equations y = -2x + b and y = -1/2x + b , now we can just make up number for b so the two equations are
- y = -2x + 3
- y = -1/2x + 5
- Then we solve them by substituting for y so
- -1/2x + 5 = -2x + 3 and x = -4/3
- and then we put this to get y in either equation
- y = -2(-4/3) + 3
- y = 17/3
- So the equations work
