Item Time bought
MIcroscopes Every 5 years
Safety goggles Every 4 years
Test Tube Every 2 years
It would take 20 years for them to buy these three items at the same time.
We simply need to find the LCM or least common multiple of the 3 items using the number of years.
Microscopes - 5 years → 5, 10, 15, 20
Goggles - 4 years → 4, 8, 12, 16, 20
Test tubes - 2 years → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
The correct answer is
y=2x-9
Since the lines are parallel, they will gave the same slope (in this case it’s 2)
Our equation will be
y=mx+b
We know the slope is 2, and they’ve given us x and y coordinates. Plugging it in to the slope equation we get
1=2(5)+b
1=10+b
Subtract 10 from both sides and you get
-9=b
Putting it together our new parallel line will be
y = 2x - 9
Answer:
the ratio is 1 : 1.75
Step-by-step explanation:
Answer: a is in quadratic form
Answer:
1) ≤ 200 (less than or equal to 200 lb because Imani cannot have more than 200)
2) ≥ 45 (greater than or equal to 45 miles because Johnathan's drive is 45 miles or more)
