Slope = (10 - 5)/(-9 + 15) = 5/6
y = mx + b where m = slope and b = y-intercept
b = y - mx
b = 5 - (5/6) (-15)
b = 5 +12.5
b = 17.5
Equation y = 5/6 x + 17.5
Y-intercept = 17.5
X-intercept when y = 0
So
5/6 x + 17.5 = 0
5/6 x = -17.5
x = (-17.5) (6/5)
x = -21
Answer
Y intercept (0, 17.5 )
X intercept (-21 , 0)
6.45 + 19.82 = c) 26.27
64.5 + 1.983 = a) 66.483
6.45 - 1.983 = b) 4.467
64.5 - 19.83 = d) 44.67
The answer is <span>A. 2 eggs / 3 cups of flour = 12 eggs / 18 cups of flour because 2 x 18 = 3 x 12 = 36.</span>
The <u>correct answer</u> is:
The better deal is $10.90 for a dozen.
Explanation:
A <u>unit rate</u> is a rate with a denominator of 1. This means we want to know the price of one individual desk for each bulk package.
$10.90 for a dozen desks:
Divide 10.90 by 12:
10.90/12 = 0.9083 ≈ $0.91 per desk.
$80 for 60 desks:
Divide 80 by 60:
80/60 = $1.33 per desk.
The lowest cost per desk is in the $10.90 for a dozen deal.
