Answer:
m = 3/5
Step-by-step explanation:
Slope Formula:
Step 1: Find 2 coordinates
(0, 80)
(-50, 50)
Step 2: Find slope <em>m</em>
m = (50 - 80)/(-50 - 0)
m = -30/-50
m = 3/5
Answer:
h( x ) = ( x + 1 )^2 - 4 x(h)×(÷×1)^2-4
This is how i worked it out.
Good Luck
Pythagora: 20^2=(4x)^2+(3x^2)
400=16x^2+9x^2
x^2=400/25
x^2=16
x=4
