2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5
The answer is d its decreasing
The horizontal distance that's traveled by the golf ball based on the velocity given is 138.56feet.
<h3>How to compute the distance?</h3>
From the information given, the golf ball has been hit off of the tee at an angle of elevation of 30 degrees and an initial velocity of 160 ft/sec.
The distance will be:
= 160 × cos30°
=160 × 0.866
= 138.56 feet

Convert to slope / intercept form:-
4x + 5y = -2
5y = - 4x - 2
y = -4/5 x - 2/5
the slope of this line is -4/5 and slope of line perpendicular to it is - 1 / -4/5
= 5/4 answer
Answer:
y=-3
Step-by-step explanation:
First, you want the slope.
The slope is
0/-8 = 0, so the line is horizontal.
the y-intercept must be -3 because it never changes.
So the equation must be
y=-3
