3 0

1st equation: x +y =5

 2nd equation: x = y +7

replace x in 1st with 2nd

y +7 +y =5

2y+7 =5

2y =-2

y = -1

now replace y in 2nd with -1

x = -1 +7

x = 6

answer:

x = 6

y = -1

A line passes through (-1,7) and (2,10) which answer is the equation of the line
alekssr [168]

Answer: -x + y = 8

Step-by-step explanation:

So first you are going to want to find the slope of the equation. The equation for that it (y2 - y1)/(x2 - x1) = (10 - 7)/(2 - -1) and that equals 1. So your slope will be 1.

Now you have half of your equation complete, currently it looks like, y = x + b. So we have to find the y intercept. You can do that by plugging in a pair of coordinates into the current equation and solve for b.

Lets plug in (2,10)

10 = 2 + b

10 - 2 = b

b = 8

So now you have your equation in slope intercept form, y = x + 8. Just move the x over to the left side and there is your answer.

-x + y = 8

The result of the product of the sides of the triangles is 9

<h3>Shapes and Patterns</h3>

From the given diagram, you can see that the triangle and the shape circumscribed around it forms patterns given as:

  • Product = sides of the triangle * number of sides of the circumscribed shape

For the circle and triangle

Product = 0 * 3

Product = 0

For the rectangle and triangle;

Product = 3 * 4

Product = 12

For the two triangles

Product = 3 * 3

Product = 9

Hence the result of the product of the sides of the triangles is 9
