Answer:
Which plant was taller when Nara got the plants? C. They were equally tall
Which plant grew faster? B. The second plant
Step-by-step explanation:
Slope of the first plant :
m = (y2 - y1)/(x2- x1)
m = (36 - 34)/(15 - 10) = 0.4
y-intercept of the first plant :
y = m*x + b
b = y1 - m*x1
b = 34 - 0.4*10 = 30
From the picture we can see that the y-intercept of the second plant is 30 cm
Y-intercept represents plant heights when Nara got the plants; then they were equally tall
From the picture we can see that second plant grew 2 cm in 2 days; then its slope is 2/2 = 1
Slope measures how fast each plant grew; then the second plant grew faster
Answer:
6
Step-by-step explanation:
6 ^ (1/4) ^ 4
We know a^ b^ c = a^(b*c)
6 ^ (1/4*4)
6^1

Answer:
Linda makes 3 more cards than Paul.
Step-by-step explanation:
Let's express the affirmations into equations:
Paul (P) can make 1 card for every 3 cards Linda (L) makes:
(1)
Linda can make 3 cards for every 2 cards that Aaron (A) makes:
(2)
During a week, Aaron makes 72 cards, hence the number of cards of Linda and Paul can be calculated as follows:
From equation (2):
Now, from equation (1):
Finally, the number of cards that Linda makes more than Paul is:
Therefore, Linda makes 3 more cards than Paul.
I hope it helps you!
