Complete the square:
x^2 - 12x + (-6)^2 - (-6)^2 = 61, or
(x-6)^2 -36 = 61, or
x-6 = plus or minus sqrt(97), or
x = 6 plus or minus sqrt(97)
Meters are 100 times as large as centimeters. So, if we have 800 centimeters, that is the equivalent of 8 meters.
In this scenario, we want to know how many meters is equivalent to 7
centimeters. Since 1 centimeter is 1/100 of 1 meter, we can multiply the
amount of centimeters by 1/100 to get the measurement in meters.
7(1/100) will yield 7/100 or .07 meters.
To write this in scientific notation, we take 7 and multiply it by 1/100 or 10^(-2). This is written "7x10^(-2) m".
7 centimeters in scientific notation is just 7x10^0 because it is a
single unit. Scientific notation allows us to compare the size of
numbers more easily.
For instance 7.12x10^3 is much larger
than 7.12x10^(-3) due to the exponents and how many "10s" we are
mulitplying our number by.
Answer:
I will assume that the term "x+2/2" is meant to be "(x + 2)/2)." Otherwise the equation would read (x/3) = x + 1
Step-by-step explanation:
(x/3) = (x + 2)/2
x = 3*(x+2)/2 [Multiply both sides by 3]
x = (3x + 6)/2
x = (3/2)x + 6/2
x - (3/2)x = 3
-0.5x = 3
x = -6
====================
Check:
Does (x/3) = (x + 2)/2 for x = -6?
(-6/3) = (-6 + 2)/2
-2 = -4/2
-2 = -2 YES
Answer:
Step-by-step explanation:
on the triangle.
I think that is right as I just was reading on this.
The answer to this is y=11x
