3y-6=3x and y+2x=5 solve the system of linear equations by graphing PLEASE SHOW WORK​
Dmitry_Shevchenko [17]

Answer:

  (x, y) = (1, 3)

Step-by-step explanation:

The "work" of solving by graphing is typing the equations into a graphing calculator and highlighting the point of intersection.

___

If you're graphing these by hand, there are a couple of strategies you can use. One is to make use of the intercepts of the line. For each of these, you need to rearrange the equation to a suitable form.

  <u>3y -6 = 3x</u>

To put this into "intercept form", put the variable terms on one side of the equal sign and the constant on the other. Then divide by the constant and express the resulting variable coefficients as denominators.

  3x -3y = -6

  x/(-6/3) +y/(-6/-3) = 1

  x/(-2) + y/2 = 1 . . . . . . The x-intercept is -2; the y-intercept is 2.

Plot the intercept points and draw a line through them.

  <u>y +2x = 5</u>

The intercepts for this one are found by dividing by 5:

  x/(5/2) + y/5 = 1 . . . . . . The x-intercept is 2.5; the y-intercept is 5.

The other strategy you can use for this one is to rearrange the equation to slope-intercept form and make use of those numbers.

  y = -2x + 5

The y-intercept is 5 (as we already found above), and the slope is -2. That means the line drops 2 units for each unit it goes to the right. Apart from the y-intercept, other points on this line will be (1, 3), (2, 1), (3, -1).

  <u>Solution</u>

When you plot these lines, you find they intersect at (1, 3). That is the solution to the system of equations, the values of x and y that satisfy both equations.

kipiarov [429]

Answer:

C : does not have statistical significance

Step-by-step explanation:

Because there is a 15% chance of getting that many girls by chance, the method - does not have statistical significance.

By this method, the percentage of girls = 1067/2086=0.5115 or 51.15%

This type of method does not have practical significance.

1.The price of a coat was priced at $300. It went on sale after Christmas. It had a 22% discount. What was the sale price?
LekaFEV [45]

Answer:

1. $234

2. B) 6

Step-by-step explanation:

1. Since the coat is on sale for 22% off you want to do 300 times 0.22 to get 66. With this number you are going to take 300-66 to get $234.

2. The formula for the volume of a rectangular pyramid is V= lwh/3

Since I know that the total volume is 120 I know that the l times w time h has to equal 360 since its divided by 3. With the 12 and 5 I get 60. Since I know that 360/60 equals 6 I know the answer is B.
