Answer: -1
Step-by-step explanation:
Given: The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear
The slope of a line passing through points (a,b) and (c,d) is given by :-
Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-
Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
Answer:
Option 3. -8
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
----> the isolated constant right side is -8
Rewrite as perfect squares
Square root both sides
Answer:
6/12
Step-by-step explanation:
A fourth of 8 is 2, so there would be 6/12 of the tub of frosting left.
Answer: you put 9.655 in the account when you opened it
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount of money deposited.
P represents the principal or amount of money deposited.
R represents interest rate on the deposit.
T represents the duration of the deposit in years.
From the information given,
Amount earned = 9.80
I = 9.8 - P
R = 6%
T = 3 months. There are 12 months in a year. Converting 3 months to year, it becomes 3/12 = 0.25 year
Therefore
9.8 - P = (P × 6 × 0.25)/100
9.8 - P = 0.015P
0.015P + P = 9.8
1.015P = 9.8
P = 9.8/1.015
P = 9.655
