What is the solution of this system of linear equations? 3y = x + 6 y – x = 3

Greeley [361]

Hello :
3y = x + 6 ...(1)
y – x = 3...(2)
by (2) : y = x+3...(*)
subsct in (1) :
3(x+3) = x+6
3x-x= -9+6
2x= -3
x=-3/2
subsct in (*) : y =-3/2 +3 =3/2

Which answer does NOT correctly describe the graph of y = 5x + 12?

Dafna11 [192]

Answer:

The graph contains the point (5, 12) does NOT correctly describe the graph of y = 5x + 12

Solution:

Given, linear equation in two variable is y = 5x + 12.

We have to select the option that incorrectly describes about given equation.

Now, we have to check one by one option.

a) The line has a constant rate of change.

As the given line is an linear equation it will have constant slope. So this option states correctly

b) The line crosses the y-axis 12 units above the origin

When a line crosses y – axis it x value becomes 0 → y = 5(0) + 12 → y = 12

So, the line crosses the y – axis 12 units above the origin, so this option states correctly.

c) The graph contains the point (5, 12)

To contain (5, 12) in that line → 12 - 5(5) + 12 = 0 but -1 ≠ 0

So, this option is incorrect.

Hence, option c incorrectly describes about the graph.

How do you solve −2x−4=3x+1 by graphing

crimeas [40]

Answer:

Step-by-step explanation:

You first have to simplify...

-2x-4=3x+1 (-1 both sides)

-2x-5=3x (+2x both sides)

-5=5x

-1=x

So graphing that would be a vertical line on -1.

What is the radius in centimeters of a circle that has a circumference of 16 centimeters

Whitepunk [10]

If I did this correctly all you hade to do is work in reverse.
1.) Divide 16 by pi (3.14) To get the diameter.16/ 3.14 =5.095541401 or 5.1
2.) Since Diameter is just the radius doubled divide 5.1 by 2. 5.1 /2 = 2.55
3.) Plug it in, use the 2pir equation to see if it works. 2X3.14X2.55= 16.014 or 16.
I hope this helps, let me know if you need further explanation.
