Answer:
Option B. y = 2x; 20 feet
Step-by-step explanation:
1. Determination of the equation that represents the relationship.
Let y be the distance travelled.
Let x be the time taken.
Let K be the speed.
From the question given above, the following data were obtained:
Distance (y) = 80 ft
Time (x) = 40 s
Speed (k) =.?
Speed = Distance /time
K = y/x ......... (1)
K = 80/40
K = 2 ft/s
Substitute the value of k into equation 1
K = y/x
K = 2 ft/s
2 = y/x
Cross multiply
y = 2x
Therefore, the equation that represents the relationship is y = 2x
2. Determination of the distance travelled in 10 s.
Speed (k) = 2 ft/s
Time (x) = 10 s
Distance (y) =.?
y = 2x
y = 2 × 10
y = 20 ft
Therefore, the person will travel 20 feet in 10 seconds.
From the above calculations, the right answer to the question is
Option B. y = 2x; 20 feet

what is 7a to the power of 2 - 2a to the power of 2
Answer:
5a to the power of 2 ofc
Step-by-step explanation:
Answer:
5a²
Step-by-step explanation:
It is 5a² because 7a² and 2a² are like terms, so we are able to subtract them. If we subtract 7-2 we get 5. It is the same thing, 7a²-2a² is equal to 5a²
Hope this helps!

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers
Answer: t 0<t<3
Step-by-step explanation:
Answer:
The correct option is 1.
Step-by-step explanation:
The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.
The value of height and time can not be negative, there the values of h and t must be greater than 0.
The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.
The graph is defined from t=0 to t=3.
Therefore option 1 is correct.
Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys. 1) Which inequality describes this scenario?
This scenario is described by the following inequality:
[tex]2.5 + 5B \leq 21[/tex]
-------------------------
First, we find Alonso's total spendings.He spends $2.50 in eggs.After that, he buys B bags of avocados, each costing $5, and thus, his spending on avocados is: [tex]5B[/tex]His total spending is given by:[tex]T = 2.5 + 5B[/tex]
-------------------------
He brought $21 to the market, thus, his total spending can be at most $21, that is:[tex]T \leq 21[/tex]
Replacing the equation for T, the inequality is:
[tex]2.5 + 5B \leq 21[/tex]

The set of ordered pairs (t, m) where m is
the remaining mass of a 500-gram sample
of a radioactive substance that has been
decaying for t hours.
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
What is LaTeX: m\angle PTQm ∠ P T Q?
line ps intersecting with line qr at point t. angle ptq is x + 28 degrees. angle rts is 2x + 16 degrees.
Group of answer choices
140
40
50
12
Answer:
B. 40Step-by-step explanation:
If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)
Given
PTQ is x + 28
RTS is 2x + 16
Since they are both equal, then x+28 = 2x+16
collect like terms
x-2x = 16-28
-x = -12
multiply both sides by -1
-1(-x) = -1(-12)
x = 12
Since ∠ P T Q = x+28, substitute x = 12 into the function
∠ P T Q = 12+28
∠ P T Q = 40
Hence measure of ∠ P T Q is 40°
what is the result when the number 28 is increased by 9%
Answer: The answer should be 25.48
Step-by-step explanation: You are multiplying .9 to 28. (28 x .9)

I don't understand Division. Can you help?
Answer:
It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2, think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.
