Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y =
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4
2. F = ma
a.) Solve this equation for a (isolate the a)
F = ma Divide m on both sides

b.) F = -25
m = 10
a = ?


a = -2.5
c.) F = 25
a = 5
m = ?
F = ma
25 = m(5) Divide 5 on both sides
5 = m
(don't forget the units, because I forgot to put the units)
Just write an equation on each one
Answer:
y=-x-2
Step-by-step explanation:
The line passes through the points -2,0 and 0,-2. The line is slanted towards the left so the line has a negative slope.
equation of line with negative slope: y=mx+b
using the rise over run tactic: 2/2= 1
y=-x+b
the y intercept is 0,-2
y=-x-2
Answer:
Comic Books
a: y=-10x+90
b: He will have 10 books at the end of the seventh day.
Step-by-step explanation:
A: Take two points. The y-intercept is (0,90). The graph decreases by 10 each day.
B: Look at day 8.
