Hello once again!
When you see a question like this, you need to find the equation of the straight line.
The formular used is y = mx + c
Where
m = slope
c = constant
First find the slope, since it's a straight line, any 2 coordinates can be used.
Now we need to substitude in the slope, and one of the coordinate you used to find the slope, to the formular to find the constant.
In this case i'm using the coordinate
(-2, 16)
y = mx + c
16 = -6(-2) + c
16 = 12 + c
c = 4
∴ The equation of the line is y = -6x + 4
The next step is to simply substitude in the x = 8 to the equation to find y.
y = -6(8) + 4
y = -48 + 4
y = -44
To solve this problem you must use the information given in the problem above:
1. You have that he jogs to the park and then to the playground, then he jogs miles to the bridge and to his house.
2. Therefore, as you can see, Jerry completes his jog when he arrives to his house. So, he is from his house.
Then, the answer is:
Answer:
<h2>2.2</h2>
Step-by-step explanation:
Use the cosine law:
We have:
