Is (2, 2) a solution of y < 4x - 6?<br> Choose 1 answer<br> yes or no

zalisa [80]

No, (2,2) is not solution of y < 4x - 6

Step-by-step explanation:

To solve above linear problem, we use standard method of Back- Substitution.

First of all, A point (2,2) only becomes solution of equation, if it satisfies equation $y < 4x - 6$ .

Here, the $y < 4x - 6$ seems to be like a linear equation.

In this Equation, using Back- Substitution method,

Point (2,2) : first digit 2 corresponds to x- coordinate and second digit 2 corresponds to y-coordinate.

$y < 4x - 6.....(1) \\\ x= 2 .....(2) \\\ y= 2 .....(3)$

By putting value of x and y in equation (1),

Equation becomes,

$2 < 4 \times 2 - 6$

$2 < 8 - 6$

$2 < 2$ .... not true mathematically.

Finally, the result came is not true. Therefore, (2,2) is not solution for equation

$y < 4x - 6$

Total health care costs in the United States in 2016 was $1.7 trillion. he US population was 290.9 million. What was the average

dusya [7]

Answer:

$5,843.9

Step-by-step explanation:

2016

Total health care cost in US = $1.7 trillion

= $1,700,000,000,000

Population in US = 290.9 million.

= 290,900,000

Average amount spent per person on health care = Total health care cost in US / Population in US

= 1,700,000,000,000 / 290,900,000

= $5843.9326228944

Approximately,

$5,843.9

To the nearest whole number

= $5,844

Write a system of linear equations that has the ordered pair (1,4) as it's solition

Lemur [1.5K]

The required system of equations is $x+y=5\\x-y=-3$

Step-by-step explanation:

We need to write a system of linear equations that has the ordered pair (1,4) as it's solution.

It means we need to find system of linear equations, which after being solved gives x=1 and y=4

Let the system of equations be:

$x+y=5\\x-y=-3$

I have made equations such that adding x+y gives 5 i,e (1+4=5) and subtracting x-y gives -3 (1-4=-3)

Now solving this system of equations to find value of x:

$x+y=5\,\,eq(1)\\x-y=-3\,\,eq(2)$

Adding eq(1) and eq(2)

$x+y=5\\x-y=-3\\-----\\2x=2\\x=1$

Putting value of x=1 into eq(1) to find value of y

$x+y=5\\1+y=5\\y=5-1\\y=4$

The solution set after solving system of equations is (1,4).

The required system of equations is $x+y=5\\x-y=-3$
