Cup A
<em><u>Formula</u></em>
V = 1/3 pi r^2 h
<em><u>Givens</u></em>
r = d/2 = 2/2 = 1 inch
pi = 3.14
h = 4 inches
<em><u>Solution</u></em>
V = 1/3 * 3.14 * 1^2 * 4
V = 4.187
Cup B
<em><u>Formula</u></em>
V = pi * r^2 * h
<em><u>Givens</u></em>
pi = 3.14
r = d/2 = 2/2 = 1
h = 6
<em><u>Solution</u></em>
V = pi * r^2 * h
V = 3.14 * 1^2 * 6
V = 18.84
<em><u>Answer</u></em>
VB - VA = 18.84 cu in - 4.187 = 14.65 = 14.7 Rounded.
Answer C
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 3
b = -2 So substitute/plug it into the equation
y = mx + b
y = 3x + (-2)
y = 3x - 2 Your answer is the 2nd option
So you do
distribute
a(b+c)=ab+ac
9(x+5)=9x+9 times 5=9x+45
7(x-3)=7x+7 times -3=7x-21
so now we have
9x+45+7x-21
group like terms
9x+7x+45-21
add
16x+24
simplified is 16x+24
