Answer: H
Step-by-step explanation:
<span>1. Make y the subject
a) 4y=12x+18
y = 3x + 4.5
b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3
2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)
slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1
equation
y = 2.5x + 1
b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)
</span>y= 1/2X + 7
slope = 1/2
slope of line perpendicular = -2
passing through point (3,9)
y = mx + b
9 = -2 (3) + b
b = 15
equation
y = -2x + 15
Answer:

Answer:
1 second
Step-by-step explanation:
y = -16x² + 32x
y = -16(x² - 2x)
y = -16(x² - 2(x)(1) + 1² - 1²)
y = -16(x - 1)² + 16
Max height is when (x-1) = 0
So x = 1
4 divided by 2 is 2. So, 1/2 of one bar goes to each player.
