X = 9 - 3, does this help?
Tanzania [10]3 years ago

Answer:

The original solution of the equation

  x=6

Adding 3 on both sides, gives

x+3=6+3

x+3=9

 x=9-3

So,Addition of 3 on left hand side or subtraction of 3 from 9 in right hand side gives solution x=9.

Need some help, please. What do I plot? I attempted to figure the questions out many times, but I've come to no clear conclusion
olganol [36]

Answer:

vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)

Step-by-step explanation:

The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.

So you can plot (6,0) and (2,0).

The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4

We just have to find the y-coordinate for when x=4.

Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.

So the vertex is at (4,-4).

What is the length of the actual dining room?
Schach [20]
120 inches.

This is because to find the scale factor, you have to take the square root of the area scale. This will give you 30-1 ratio. Then multiply the 4 by that number.
