Red oak trees grow at a rate of about 2 feet per year. You buy and plant two red oak trees, one that is 6 feet tall and one that is 8 feet tall. The height h (in feet) of the shorter tree can be modeled by h=2t+6 where t is the time (in years) since you planted the tree. The height of the taller tree can be modeled by h=2t+8.
A. Graph both equations in the same coordinate plane.
B. Use the graphs to find the difference of the heights of the trees 5 years after you plant them. What is the difference after 10 years? What do you notice about the difference if the heights of the two trees?
Answer:
A: I think it's A because you need to graph both equations
Answer:
These are the screenshots of the work I did and more of the actual answer for graphing but basically,
The difference in heights of the trees after 5 years is 2 feet, after 10 years is 2 feet, and after any number of years is 2 feet since the lines are parallel.

The parts of the graph where it is going 'up' are where it is increasing.
This is between x = - 4 to x = 0 and between x = 5 to infinity
Expressing in interval form the graph is increasing for
(- 4, 0 ) and (5, ∞ )
What angle relationship is demonstrated by x and y?
Answer:
corresponding angles
Step-by-step explanation:
x and y are in the same position in relation to the lines. They are to the right of the transversal and above the horizontal lines.
This means they are corresponding angles

In March, Isaiah and Freddie had the same amount of money in their savings accounts. In April, Isaiah deposited $210 into his account. Freddie increased the money in his account by 15%. When they compared their balances, they found that they were still equal.
How much money did they both have in their accounts in March?
Enter your answer in your box.
Answer:
let the amount deposited by each of them in march be m.
in April, Isaiah deposited 210$, this means the amount in his account became m+210
Freddie increased the amount by 15%, this means that the amount of money in his account became: m+0.15m
since both values are still equal, we will equate both equations and solve for m.
m+210 = m+0.15m
0.15m = 210
m = 1400$

Item 4 Multiply. [−12 ⋅ 4/7]⋅[−14⋅(−0.1)] What is the product? Enter your answer in the box.
Answer:
-9.6
Step-by-step explanation:
The product of the given expression [−12 ⋅ 4/7]⋅[−14⋅(−0.1)] is approximately -9.6.
We have,
Let's break down the expression step by step:
[−12 ⋅ 4/7]⋅[−14⋅(−0.1)]
First, let's simplify the expressions inside each set of brackets:
-12 ⋅ 4/7 = -48/7
-14 ⋅ (-0.1) = 1.4
Now, substitute these values back into the original expression:
[-48/7]⋅[1.4]
Now, multiply the two fractions:
(-48/7) * 1.4 = -67.2 / 7
This can be simplified further by dividing both the numerator and the denominator by their greatest common divisor, which is 1:
-67.2 / 7 ≈ -9.6
Thus,
The product of the given expression is approximately -9.6.

Answer:
6 favors each guest
Step-by-step explanation:
3 bag if 12 means total 36
She has divided evenly amongst 6 guest .
36/6 = 6each guest.
Answer:
The answer would be 6.
Step-by-step explanation:
Assuming, Amy doesn't have a sweet tooth, she's only giving party favors to her own guests.
There are 3 bags of 12 party favors each. This gives us a total of 36 party favors.
There are 6 guests and so to evenly split the party favors, we must split 36 into 6 groups, giving us 6 party favors in each group.
COMPUTATION:
3 x 12 = 36
36 / 6 = 6

Answer:
see attached
Step-by-step explanation:
The ratio of the given terms is the common ratio raised to a power equal to the number of means plus 1.
1)For example, the common ratio in the sequence 5, __, 20 will be r, where ...
r^2 = 20/5 = 4 ⇒ r = 4^(1/2) = 2
Then the mean is found by multiplying 5 by this ratio: 5×2 = 10.
__
2-5)The same method is used for finding the common ratio and then the intermediate means. Each mean is the previous term multiplied by the common ratio. Results are summarized in the attached table.

The function t(x) = 4x -2 determines how many cans of vegetables a food truck needs to stock on board, where x is the number of shifts the crew is going to work in the truck. The crew uses c(t(x)) to find the amount of money to spend on vegetables. The function c(x) = x + 9. Solve for how much money must be spent when the crew is going to work 2 shifts.
Answer:
[tex]t(x) = 4x - 2 \\ c(x) = x + 9 \\ c(t(x)) = (4x - 2) + 9 \\ = (4(2) - 2) + 9 \\ = 8 - 2 + 9 \\ = 6 + 9 = 15[/tex]
