You can only see the top sentence
5 is the answer
here we have hypoteaus and base
so by using pythagoreaus theorem
p^2 = h^2 - b^2
p^2 = 13^2 - 12^2
p^2 = 169 - 144
p^2 = 25
p = root under 25
<em><u>p = 5</u></em>
Answer:
It intersects the x-axis at x = 10
Step-by-step explanation:
Step 1: Find slope <em>m</em>
m = (5 - 1)/(5 - 9)
m = 4/-4
m = -1
y = -x + b
Step 2: Find <em>b</em>
5 = -5 + b
b = 10
Step 3: Rewrite equation
y = -x + 10
Step 4: Find <em>x</em> when <em>y</em> = 0
0 = -x + 10
-10 = -x
x = 10
So the graph crosses the x-axis at 10.
Answer:
6 mph
Step-by-step explanation:
Speed = Distance/Time. Distance is 18, time is 3. So 18/3, or 6.
