Adjacent means next to or adjoining something else. therefore an adjacent angle to <DGE would be <HGJ
The value of y can be calculated by translating the equation such that we solve y in terms of x.
-3x - 8y = 10
-8y = 10 + 3x
y = (10 + 3x) / -8
Then, we substitute 2 to the x in the equation.
y = (10 + 3(2)) / - 8 = 16/-8
y = -2
Thus, the value of y in the equation is -2.
So hmm check the picture below

a)
well, clearly is 80 ft/s
b)
when t = 1? well 80(1)
c)
in the picture, x-axis is the time and y-axis is the height
so, it reaches its maximum at the vertex, after "x" seconds

so it reached the vertex after

d)
the maximum height of the ball is
Answer:
-200
Step-by-step explanation:
if youre doing normal addition youd get 200 + 200 giving you 400 so -200 + -200 = 400
12/30=0.4 or 40% finished
18/30=0.6 or 60% did not finish
