The sum of two numbers is eight one number is four less than the other find the numbers
mash [69]

Step-by-step explanation:

the numbers : x, y

x + y = 8

x = y - 4

we use the second equation in the first :

y - 4 + y = 8

2y - 4 = 8

2y = 12

y = 6

x = y - 4 = 6 - 4 = 2

Identify all of the following solutions of square root of x minus 8 end root plus 8 equals x.
Anit [1.1K]
\sqrt{x-8} +8=x \\  \sqrt{x-8} =x-8 \\  {( \sqrt{x-8} )}^{2} = {(x-8)}^{2}  \\ x-8= x^{2} -16x+64 \\  x^{2} -16x-x+64+8=0 \\  x^{2} -17x+72=0

(x-8)(x-9)=0 \\ x-8=0 \ and \ x-9=0 \\ x=8 \ and \ x=9

What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?
riadik2000 [5.3K]

Answer:

The distance is 1.41 to nearest hundredth.

Step-by-step explanation:

The line y = x + 3 passes through the point (0, 3) on the yaxis.

Find the perpendicular line passing through this point:

y  - 3 = -1(x + 0)

y = -x + 3

Now find the point where this line intersects the line y = x + 1:

y = -x + 3

y = x + 1

-x + 3 = x  + 1

3 -1 = x + x

2x = 2

x = 1

and y = 2

So this point is (1, 2)

We require the distance between this point and (0, 3)

This = √((3-2)^2 + (0-1)^2) = √2

= 1.4142
