Solve the system of linear equations using any method.
-6y + 2 = -4x
y – 2 = x

Answers

Answer 1

Answer:

x=-5 and y=-3

Step-by-step explanation:

-6y+2=-4x convert this into standard form

  y=x+2

  plug in the slope intercept form in to y

  -6(x+2)+4x=-2

  -6x-12+4x=-2

  -2x-12=-2 now solve for x

  -2x-12+12=-2+12

  -2x=+10

  x=-5 now solve for y

  y=-5+2

  y=-3

  so basically x=-5 and y=-3

Answer:

1.65 km or 33/20 km per minute, 16.5 km or 33/2 km ( for the second question)

Step-by-step explanation:

There's 60 minutes in an hour, so just divide 99 by 60, then you'll get either 1.65 or 99/60 which is simplified to 33/20. And for the second question, multiply the answer from the first question by 10.

The graph shows Victor's math scores versus the number of hours he studies: A graph titled Victors Math Scores shows Hours of Practice in a Week on x axis and Math Scores on y axis. The x axis scale is shown from 0 to 5 at increments of 1, and the y axis scale is shown from 0 to 50 at increments of 5.The ordered pairs 0, 5 and 0.5, 10 and 1, 16 and 1.5, 20 and 2, 27 and 2.5, 28 and 3, 35 and 3.5, 34 and 4, 44 and 4.5, 44 and 5, 48 are shown on the graph. A straight line joins the ordered pairs 0, 5 and 5, 50. What will Victor's math scores most likely be if he spends 7 hours a week studying math? 58 points 62 points 68 points 72 points

Answers

Answer:

68

Step-by-step explanation:

Because it's going up 15 every 2 hours so it would go from 50 to about 65 so 68.

Coordinates of Points

A point is the basic relationship displayed on a graph. Each point is defined by a pair of numbers containing two coordinates.

A coordinate is one of a set of numbers used to identify the location of a point on a graph.

Identifying the x-coordinate

The x-coordinate of a point is the value that tells you how far from the origin the point is on the horizontal, or x-axis. To find the x-coordinate of a point on a graph:

- Draw a straight line from the point directly to the x-axis.

- The number where the line hits the x-axis is the value of the x-coordinate.

Identifying the y-coordinate

Now that you know how to find the x-coordinate of a point, you have to be able to find the y-coordinate.

The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:

- Draw a straight line from the point directly to the y-axis.

- The number where the line hits the axis is the value of the y-coordinate.

Notation for Identifying Points

Once you have the coordinates of a point you can use the ordered pair notation for labeling points. The notation is simple. Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first.

Question If Jim has 60 spoons and Jim has a friend named Jim that has 157 and has another friend named Jim with 537 spoons and pooled all their spoons together and Jim 1 took the spoons to a blacksmith to make small spoons by breaking the spoons to thirds and 27 spoons broke, Jim 1 had the blacksmith make a normal spoon from the remains which makes 3 normal spoons how many spoons do all the Jims have together and how many spoons do each Jim have individvally? I just thought of this on the spot so i dont know the answer anywho I need an answer cause i wanted to ask this to my friends and say the answer to seem smart lol

Answers

Step-by-step explanation:

Jim 1= 60 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

after Jim 1 took the spoons to the blacksmith he broke 27 spoons which means

Jim 1= 60-27 which leaves him with 33 spoons.

and now

Jim 1= 33 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

3 normal spoons outta 33 spoons which means he used 11 spoons per each spoon

and now

Jim 1= 3 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

so finally, all the Jims have 697 spoons in total.
