Answer:
Step-by-step explanation:
we know that
The equation of a line in point slope form is equal to
step 1
Find the slope m
we have the points
A(-2,-1),B(6,5)
The formula to calculate the slope between two points is equal to
substitute the values
simplify
step 2
Find the equation of the line
we have
substitute
(2,5)(-1,8)
slope = (8 - 5) / (-1 - 2) = 3/-3 = -1
y - y1 = m(x - x1)
slope(m) = -1
(2,5)...x1 = 2 and y1 = 5
now we sub
y - 5 = -1(x - 2) <==
Answer:
Step-by-step explanation: total income=$500
Ratio of partition of money6:3:4
( Which gives that lauren gets 6x, rachel gets 3x and Becca gets 4x)
6x+3x+4x=500
13x=$500
X=500/13 ( transposition method)
x= 38.46
So lauren gets 6(38.46)… rachel gets 3(38.46)while Becca gets 4(38.46)…
Lauren= 230.76
Rachel=115.38
Becca= 153.84
Answer: If the 40% off coupon is used, the subtotal will be $12.69
The gratuity would be exactly $4.23 (He will probably leave $4.25)
Step-by-step explanation: To find out the amount of the discount
.40 × 21.15 = 8.46
To find the new subtotal, subtract 12.15 - 8.46 = 12.69
To figure the tip: .20 × 21.15 = 4.23
Changing the percent to a decimal means divide the 20 by 100.
