x² + x² + x² = 6

3x²=6

Divide both sides by three

x²=2

Take the square root of both sides

x=1.41421356237...

You can make NO triangles.

When given 3 sides of a triangle, The longest side must be LESS than the sum of the other 2 sides.

Longest Side = 50 cm

50 is NOT less than 14 + 10, therefore, we have no triangle.

Is x+3=-5y in standard form?
skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is Ax+By=C with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

x+3=-5y

Subtract 3 from both sides.

x=-5y-3

Add 5y.

x+5y=-3

Someone plz. help me with 7 and 8

7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25

If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25

Both sides of the equation are the same so it proves it lies on the circle

8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5

You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5

So the coordinates of Rachel's house are
(-1.5, 0.5)
