An example of a negative mixed fraction: -5 1/2. Because slash is both signs for ... fractional exponents: 16 ^ 1/2 • adding fractions and mixed numbers: 8/5 + 6 2/7
If i understand the machine correctly and -3 is x and 8 is the final answer, f(x)=x+11
Answer:as likely as not
Step-by-step explanation:
Answer:
-2.61803398875, -0.38196601125
or
(-3±√5)/2
Step-by-step explanation:
First, expand. (2x+3)² = 4x²+12x+9=5
4x²+12x+4 = 0
Quadratic equations take the form ax²+bx+c = 0
In this case,
a = 4
b = 12
c = 4
You can solve with the equation x=(-b±√b²-4ac)/2a
Plug in:
(-12±√144-64)/8
(-12±√80)/8
(-12±√2^4×5)/8
(-12±4√5)/8
(-3±√5)/2
Final answer x = (-3±√5)/2
If you want decimal form: -2.61803398875, -0.38196601125
Answer:
Darnell can run 1100 yards in 6 minutes
Step-by-step explanation:
There are 2 ways you can solve this
Method 1: You would have to divide 550 by 3 which you would get about 183, (the exact answer is very long so I recommend using a calculator). Then you multiply that by 6 to get 1100.
Method 2: This one would probably be easier. Since 3 x 2 is 6 then you can multiply 550 x 2 to get 1100.
I hope this helps!
