Answer:
-1/4
Step-by-step explanation:
-3y = 81-12x
y= 4x - 27
4m = -1 x 1/4
= -1/4
Answer:
f=-40
Step-by-step explanation:
subtract 45 from both sides
Answer:
% of increase = 2.5%
Explanation:
The percentage of increase can be calculated using the following rule:
% of increase = (amount of increase / original amount) * 100
where:
amount of increase = new price - old price = 2.89 - 2.82 = $0.07
original amount = $2.82
Substitute in the equation to get the percentage of increase as follows:
% of increase = (0.07 / 2.82) * 100 = 2.4822 % which is approximately 2.5% to the nearest tenth
Hope this helps :)
7. B) because you divide
8. B) you have to add the total amount of people then divide by 60 you will get a decimal answer but round up because you can’t have a fraction of a person.
9. B) you subtract the 2 distances

Answer:
(h+8)^2 + ( y +1)^2 = 9
Step-by-step explanation:
The equation of a circle can be written as
(x-h) ^2 +(y-k) ^2 = r^2
where (h,k) is the center and r is the radius
(h- -8)^2 + ( y - -1)^2 = 3^2
(h+8)^2 + ( y +1)^2 = 3^2
(h+8)^2 + ( y +1)^2 = 9
