Answer:
96 minutes
Step-by-step explanation:
1. find the quotient of 8 and 2.5. Which is 3.2
2. then find the product of 30 and 3.2 to get 96 minutes.
After 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
We have a line of best fit:
y = 2.5 + 1.25x
Plug x = 7 weeks
y = 2.5 + 1.25(7)
y = 11.25 units
Thus, after 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.

Answer:
Graph 2 is the cubic equation.
Step-by-step explanation:
We have been given the two graphs
So, we will conclude the function by end behavior
The cubic function enters from the left downwards and exists the graph from the right.
Cubic function will have 3 zeroes being of 3rd degree
And since the second function cuts the graph at three points
Hence, second graph is the cubic equation.
Zeroes are: -3 ,0 and 3.
Answer:
False
Step-by-step explanation:
5x - 4 versus 2x + 26
Imagine x equals 1, then the equations would be:
5(1) - 4 and 2(1) + 26
1 and 28 are not equivalent.
Another example would be x = 6
5(6) - 4 and 2(6) + 26
26 and 38 are not equivalent.
No matter what you replace x with, the expressions are never equal.
You can find the improper fractions of both.
14 1/2=29/2
1 3/5=8/5
Divide the two numbers
(29/2)/(8/5) and you will get 145/16 or 9.0625.
Therefore, you can fit 9 books on the bookshelf.
