Answer:
16
Step-by-step explanation:
Always do multiplication first:
6*4 = 24
(-2)(4) = -8
Note: A negative times a positive always equals a negative
After multipying, do addition:
24+ (-8) = 24-8 = 16
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:
c.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
You can determine if a triangle is a right triangle using the Pythagorean theorem:
Insert the given values. In a right triangle, the hypotenuse will always be the longest side, so the greatest number is c:
Simplify the exponents (x²=x·x):
Simplify addition:
Since the result is not true, the triangle is not a right triangle.
