Step-by-step explanation:
The length of the segment is 7
2-7/2 = -3/2
(1,-3/2)
Answer: p = 10
Step-by-step explanation:
4|p-3| = |2p + 8|. First multiply 4 with p and -3. You’ll get 4p-12. You will now have 4p-12 = 2p+8. You have to switch -12 & 2p, but you have to switch the signs so -12 turns into +12 and 2p turns into -2p. 4p-2p = 8+12. This makes 2p=20. Your final answer will be p = 10.
The linear function that describes Juan's elevation during his descent is:
B. y = -1460x + 7500.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, each hour, the height decays by 1460, hence the slope is of m = -1460, then:
y = -1460x + b.
The y-intercept is found considering that when x = 1, y = 6040, hence:
b = 6040 + 1460 = 7500.
Which means that option B is correct.

Answer:
15
Step-by-step explanation:
using the 3 : 4 : 5 triangle triple:
we see that this triangle follows the same ratio
9:12 = 3:4, so the hypotenuse = 5*3 = 15
