Answer:
yes x=4 is a solution
Step-by-step explanation:
45x = 180
divide each side by 45
45x/45 = 180/45
x = 4
x=4 is a solution
Answer: The mean is 27.
Step-by-step explanation: You add up all of the numbers and divide the sum by the amount of numbers you have.
Answer:
(x - 4)^2 + (y + 1)^2=9
Step-by-step explanation:
The equation of a circle can be written using a kinda of fill-in-the-blank method if you know the coordinates of the center and the radius.
If the center is (h,k) and the radius is r, then fill in those given numbers into:
(x-h)^2 + (y-k)^2 =r^2
The center of your circle is (4, -1).
Fill in 4 for the h, -1 for the k and 3 for the r.
(x-4)^2+(y- -1)^2= 3^2
Simplify.
(x-4)^2+(y+1)^2=9
The answer is A. Use the given functions to set up and simplify f(-2).
Answer: x < 39
Step-by-step explanation:
From the question, we are informed that Jordan has less than 55 minutes to finish his work and then got a phone call that lasted 16 minutes.
The inequality to show how much time he has to work will be:
x < 55 - 16
x < 39
He has less than 39 minutes
