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
You roll an eight-sided die. What is the chance that it will land on either a 2 or a 5? Write your answer as a fraction.
Answer:
2/8 and the simplified version is 1/4
Step-by-step explanation:
Answer:
2/8
Step-by-step explanation:
First you know that it is a eight- sided die. 2 or 5 are two numbers so it is 2/8.
you put all of the numbers and count them up on the top as numerators ex: 2/ Then the number of the sided die as the denominator.ex: 2/8 Hope this helped.
What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.
HELP PLS
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.
-3-2(5-9)
What is the answer
5 would be the answer i believe
Find the slope of the line passing through the points (-8,-8) and (6,-8)
Answer:
Slope = 0
So, the line is parallel to x-axis
Step-by-step explanation:
(x₁ , y₁) = (-8, -8) & (x₂ ,y₂) = (6 , -8)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\=\frac{-8-[-8]}{6-[-8]}\\\\=\frac{-8+8}{6+8}\\\\= 0[/tex]

Which pairs of events describe independent events?
Select all that apply.
A Flipping a coin and having it land with the tails side up; drawing a 7 from a standard deck of cards.
B Pulling a red sock from a drawer with 3 red socks and 5 blue socks and not replacing it; then pulling another red sock from the same drawer.
C Rolling a standard six-sided die and having it land on a 1; selecting a blue block from a tub of red and blue blocks.
D Drawing a king from a standard deck of cards and not replacing it; then drawing a queen from the same deck of cards.
Answer:
A and C
Step-by-step explanation:
Both events in A and C have no connections whatsoever. B and D are dependant of each other due to both having to do with ether both socks or both cards.
Justin calculates the perimeter of a rectangle with a length of 2x-3 and width
of X+4. He tells his teacher the answer is 3x-1. Is he correct or incorrect and why?
Answer:
No
Step-by-step explanation:
No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.
Hope this helps plz mark brainliest :D
Answer:
No, his answer should have been 6x+2
Step-by-step explanation:
The equation for perimeter is 2L+ 2W=P
so 2 (2x-3) + 2 (x+4) = 6x+2

Which number has the same absolute value as -2?
0
-1/2
1/2
2
Answer:
2
Step-by-step explanation:
The absolute value of a positive is that same number
For example the absolute value of 4 is 4
The absolute value of a negative is that same number without the negative sign.
For example, the absolute value of -4 is 4

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy
Answer:
6 laptops
Step-by-step explanation:
First, find the amount spent on the textbooks:
30(116)
= 3480
Subtract this from the total amount they have to spend:
6500 - 3480
= 3020
Divide this amount by 439 to find how many laptops they can buy:
3020/439
= 6.8
Round down to 6 since you can only have full laptops:
= 6
So, they can buy 6 laptops
