Answer:
Your answer will be
y=2x-15.5
Step-by-step explanation:
Hi, there you must know the slope-intercept form which is
y=mx+b
m=slope
b=y-intercept
You can also use
the slope formula which is
in this case
it will look like this
=
=-2
So the slope is -2
Now we will find the y-intercept
-7.5=2(4)+b
-7.5=8+b Subtract 8 both sides
-15.5=b
Your y-intercept is -15.5
Hope this helps
Answer:
Jill's feet are 17 feet from the balloon.
Step-by-step explanation:
The situation is sketched in the figure attached.
The from the ground to the balloon, the distance from Jack to Jill, and the distance from the balloon to Jill's feet forms a right triangle.
The Pythagorean Theorem says the sum of the squares of the sides of the right triangle is equal to the square of its hypotenuse :
simplifying we get
,
and take the square root of both sides to get:
Thus, Jill's feet are 17 feet from the balloon.
