The origin is (0,0)
slope = (y2 - y1) / (x2 - x1)
(-3,-2)....x1 = -3 and y1 = -2
(0,0)...x2 = 0 and y2 = 0
now we sub
slope = (0 - (-2) / (0 - (-3) = (0 + 2) / (0 + 3) = 2/3 <=
I'm assuming that x is part of the data set, and, with x, the mean equals 105. To find the value of x, you must add all the data values together to get 544+x (you still don't know what x equals). Then put 544+x over how many days values there are, including x (there are 6). You should have 544+x/6. Now, as this is how you would calculate the mean if you knew what x was equal to, you must set it equal to the mean, since you know what it is (105). You should now have 544+x/6 = 105. You have your equation set up--now you just have to solve it. I would multiply by 6 on both sides to get rid of the 6 on the left side. You would then have 544+x = 630. I would finally subtract 544 from both sides to get x = 86. Your final answer is x = 86.
Answer:
The correct option is:
1/81
Step-by-step explanation:
The given expression to us is:
(3²)⁻²
In this expression, the two powers, which are 2 and -2, are multiplying with each other, we can write it as:
(3)⁻⁴
Now we know that a negative power of a number can be converted into a positive power one if we take reciprocal of the given number.
It can be written as:
(1/3)⁴
Further simplify the expression:
1/81
Thus the correct choice from the given options is:
1 over 81 or 1/81
They could ONLY be triangles, rectangles, or nameless quadrilaterals. They couldn't be anything else.
Follow PEMDAS
first simplify the parenthesis
10 + 5 = 15
6 - 5 = 1
9(15)/1
multiply 9 and 15 together
9(15) = 135
135/1 = 135
B. 135 is your answer
hope this helps
