To solve the equation for y, we have to isolate y on one side by itself.
8x - 3 = 5 + 4y
Subtract both sides by 5
8x - 3 - 5 = 4y
8x - 8 = 4y
Divide both sides by 4
2x - 2 = y
The maximum height of the object is 82.7034 from the ground
<h3>What is Velocity ?</h3>
Velocity is the measure of movement of an object with respect to time.
It is measured in m/sec
h = -4.9t²+21.6t +58.9
dh/dt = -9.8t +21.6
At maximum height , velocity = 0
therefore
-9.8t +21.6 = 0
9.8t = 21.6
t = 2.204 sec
h = -4.9 (2.204)²+ 21.6 * 2.204 +58.9
h = -23.803 +47.606 +58.9
h = 82.7034 from the ground
h = 23.80 from the point it is launched.
The maximum height of the object is 82.7034 from the ground

Answer:
-4x^2+6x-2
Step-by-step explanation:
Answer:
x= 23
y=7
Step-by-step explanation:
x-y=16
4y-5=x
4y-5-y=16
3y-5=16 add 5 to both sides
3y=21 divide by 3 on both sides
y=7
x-7=16 substitute back in
x=23 added 7 to both sides
so x=23 and y=7
23-7=16
