Malcolm and Theo's families are both traveling to the same vacation resort.
The equation d = 65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.
Answer:
Malcom's family travel 15 miles per hour faster than Theo's
Step-by-step explanation:
See attachment for complete question
Given
Malcom's Family:
[tex]d = 65t[/tex]
To determine the equation of Theo's family, we refer to the attached graph.
From the graph:
[tex]t = 1; d = 50[/tex]
[tex]t = 2; d = 100[/tex]
First, we determine the slope, m:
[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]
[tex]m = \frac{100 - 50}{2- 1}[/tex]
[tex]m = \frac{50}{1}[/tex]
[tex]m = 50[/tex]
Next, we determine equation for Theo's family using:
[tex]d - d_1 = m(t - t_1)[/tex]
[tex]d - 50 =50(t - 1)[/tex]
[tex]d - 50 =50t - 50[/tex]
Add 50 to both sides
[tex]d - 50 +50=50t - 50 + 50[/tex]
[tex]d =50t[/tex]
So, we have the following:
[tex]d = 65t[/tex] --- For Malcom's family
This implies that Malcom's family travel at 65 miles per hour
[tex]d =50t[/tex] --- For Theo's family
This implies that Theo's family travel at 50 miles per hour
The difference between this rates is:
[tex]Rate = 65t - 50t[/tex]
[tex]Rate = 15t[/tex]
Which implies that Malcom's family travel 15 miles per hour faster than Theo's
Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Answer:
Step-by-step explanation:
A percent greater than 100% represents a comparison between one value that is greater than another value, with the second value being the base, represented by 100%. In situations like rainfall and revenue, these kinds of comparisons are common.

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement
Answer:
r+c=80
.50r+.10c=20
Step-by-step explanation:
each rose costs $0.50
each carnation costs $0.10
The number of roses is r, and the number of carnations is c.
the arrangement has a total of 80 flowers, so we have that:
r + c = 80
the cost is $20, so we have:
r*0.5 + c*0.1 = 20
so our system of equations is:
r + c = 80
r*0.5 + c*0.1 = 20
and we can also solve it; for this isolate one of the variables in the first equation:
r = 80 - c
now let'r replace this in the second equation:
(80 - c)*0.5 +c*0.1 = 20
40 - c*0.4 = 20
c = 20/0.4 = 50
this means that we have 50 carnations, and the other 30 are roses.

What is the correct answer for both?
Answer:
14) C (-2, 4)
15) D (-3, -3)
Step-by-step explanation:
-6x + 4y = 28
6x + 9y = 24
-6x + 4y = 28
4y = 28 + 6x
y = 7 + 1.5x
6x + 9y = 24
6x + 9(7 + 1.5x) = 24
6x + 63 + 13.5x = 24
19.5x + 63 = 24
19.5x = -39
x = -2
-6x + 4y = 28
-6(-2) + 4y = 28
12 + 4y = 28
4y = 16
y = 4
____________
4x - 4y = 0
-4x + 3y = 3
4x - 4y = 0
4x = 4y
x = y
-4x + 3y = 3
-4(y) + 3y = 3
-4y + 3y = 3
-1y = 3
y = -3
4x - 4y = 0
4x - 4(-3) = 0
4x + 12 = 0
4x = -12
x = -3
