2x-y=10
2x-2y=4

take the first equation an put Y by itself

y=2x-10
then plug y into the next equation

2x-2(2x-10)=4
2x-4x+20=4
-2x=-16
x=8

Now take your x and plug it into the y equation
y=2x - 10
y= 2(8) -10
y=6

x=8, y=6

Digiron [165]

Answer:

x<2 is your answer

Step-by-step explanation:

-2x+4>-4x+8

subtract each term by 8

-2x+4-8>-4x+8-8

add both side by 2x

a particular test correctly identifies those with a certain serious disease 94% of the time and correctly diagnoses those withou
Elodia [21]
This item can be solved by the probability theorem called Bayes' theorem which states that the probability of event A occurring given event B is equal to,
                            P(A/B) = P(A)P(B/A) / P(B)
where P(B/A) is the probability that the test will yield positive if the person has the disease. P(A) is the probability will be present in any particular person which is equal to 0.04. 

P(B) is the probability of positive result irrespective of whether the disease is present of not is calculated below.
                   P(B) = (0.94)x (0.04) + (0.06)(0.96) = 0.0952

Now, solving for P(A/B)
                            P(A/B) = (0.94)(0.04) / 0.0952 = 0.039
Thus, the answer is approximately 4%.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A cylindrical container that contains three tennis balls that are 5.4 inches in diameter is lying on its side and passes through an x-ray scanner that scans from the top only.

When light is fall on the cylinder then its projection will be a rectangle.

The width and diameter of the cylinder will be the same and that is equal to 5.4 inches.

And the height of the rectangle will be the same as the height of the cylinder and that is equal to 16.2 inches.

More about the geometry link is given below.
