It's C.

The value is increasing threefold relative to the previous step.

all other function values increase by a fixed amount and are therefore linear

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

Answer:

$5$

Step-by-step explanation:

Total numbers = 8

Numbers greater than 3 = 5

Therefore event space = 5

Probability

$= \frac{numbers \: greater \: than \: 3}{total \: numbers} \\ \\ = \frac{5}{8}$

Is (-4, 2) a solution of 4x + 5y <-7?

Anit [1.1K]

Answer:

Step-by-step explanation:

To solve this problem, plug the given coordinates in for x and y.

If x = -4 and y = 2, the inequality is 4(-4) + 5(2) < -7.

Evaluating 4*-4 and 5*2, the inequality becomes -16 + 10 < -7.

Evaluating -16 + 10, the inequality becomes -6 < -7.

-6 is not less than -7, so (-4, 2) is not a solution of the inequality.
