First thing to do is to switch the x and the y and then solve for the new y.  Easier said than done! Here's our equation with the switch: x=2 ^{y} +6.  We need to get that y out from inside that exponent.  This is an exponential equation, and the inverse of an exponential equation is a log equation.  Let's do some simplifying here first: x-6=2 ^{y}.  The 2 is now the base of our log (x-6) so now we have y=log _{2} (x-6), which is the last choice above.

Tomas has a garden with a length of 2.45 meters and a width of 5/8 meters.Use benchmarks to estimate the area and perimeter of t
vovikov84 [41]
The dimensions of the rectangle is 2.45 m by 5/8 m
thus the area will be:
A=length*width
A=2.45×5/8
A=1.53125 m²
Perimeter will be:
P=2(L+W)
P=2(2.45+5/8)
P=2(3.075)
P=6.15 m

11. 5x + 5 what does it equal to
Shkiper50 [21]

Answer:

Step-by-step explanation:

Okay this is an odd question, but what i'm thinking is that

first you have

5x+5

To actually be able to solve we have to move the 5 to the other side.

To do this we subtract it.

Making the equation

5x = -5

Then you need to isolate the variable (X)

So divide 5X by 5, and then divide -5/5

Which leaves you with:

x=-1

Which of the following statements demonstrates the associative property of multiplication?
professor190 [17]
Associative property of multiplication means that it doesn't matter where the parentheses are placed because it will still be the same answer.  

So your answer would be 1, 4 x (3 x 6) = (4 x 3) x 6

I hope this helps!

The diagonals of a rhombus are 12 in. and 16 in. long. The length of a side of the rhombus is 10 in. What is the height of the r
iris [78.8K]
If d₁ and d₂ are the lengths of the diagonals, the area is given by
.. A = (1/2)*d₁*d₂
.. A = (1/2)*(12 in)*(16 in)
.. A = 96 in²

If b is the base and h is the height, the area is given by
.. A = b*h
We know the values of A and b, so
.. 96 in² = (10 in)*h
.. (96 in²)/(10 in) = h = 9.6 in

The height is 9.6 in.
