<u>Answer:</u>
2.5
<u>Step-by-step explanation:</u>
We are given a graph with a positive slope where the value of y increases when the value of x increases.
For the given graph, we are to find the constant of proportionality of y to x which is the slope of the given line.
We know the formula of the slope =
Substituting the given values in the formula:
The statements that describe the given inequality are as follows:
- Riley wants to save at least $350. She earns $10 each week walking dogs. She has $75 saved. How many weeks will Riley need to walk dogs?
- Elijah would like to have at least $350 to take on vacation for spending money. He already saved $75 and plans to save $10 per week from his weekly paycheck. When will Elijah have enough money to go on vacation?
The inequality is given by:
It means that the sum of a fixed amount of 75 plus a variable amount of 10 has to be of at least 350.
Hence, the 2nd and the 3rd options are correct.

<u><em>Answer:</em></u>
He would need to climb 480.97 m
<u><em>Explanation:</em></u>
The ground, the plane to climb and the altitude (100 m) all form a right-angled triangle
Therefore, we can apply the special trig functions.
<u>These functions are as follows:</u>
sin(θ) =
cos(θ) =
tan(θ) =
<u>From the diagram, we have:</u>
θ = 12°
The distance that he needs to climb is the hypotenuse
The altitude = 100 m is the opposite
<u>Therefore, we can use the sin function as follows:</u>
sin(12°) =
hypotenuse =
hypotenuse = 480.97 meters to the nearest hundredth
Therefore, he would need to climb 480.97 meters
Hope this helps :)
