Answer:
4/5
Step-by-step explanation:
Cos 28 = 18/ y
so
y = 18 / cos 28
y = 18 /.8829
y = 20.4
Answer:
14.4
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2
Answer:
Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).
Point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)
slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2
a point is (-6,4)
x1=-6
y1=4
y-4=-1/2(x+6)
