Answer:
x=2
Step-by-step explanation:
This is an isosceles triangle you can tell by the two congruent/equal angles
angle A is congruent/equal to angle C by definition the two sides will be equal.
x-4=3x-8
1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.
x-x-4=3x-x-8
-4=2x-8
now you want to get x by itself so add 8 to both sides
4= 2x
x is still not by itself so divide both sides by 2
x=2
This polynomial is a difference of two squares.
A difference of two squares factors into the product of a sum and a difference.
Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)
Answer: ($24,890.46, $25,109.54)
The correct answer would be D and I'll explain why. The table is giving you coordinates that are supposed to be on the coordinate plane. When reading coordinates and placing them on a plane x goes before y. Therefore the first point would be (3, -4). Because 3 is x, you need to go along the x-axis until you find a positive 3 - which would be to your right. Next is -4 on the y-axis, which would be the vertical line. The positives will always be above and to the right. Since it's a negative number, you go down until you find a negative 4. Now that you've found where 3 and -4 is, see where they intersect and that's where the point will be. Now, you can continue like this for the rest of the coordinates.
There are no values of x that make the equation true so no solution.
