I took the k12 quiz
Answer:
The circle on the far left is the sum of 4x + 3y and 2x - y so the answer is 4x + 3y + 2x - y = 6x + 2y. The circle on the far left is the sum of x + 4y and something. To find that "something" we can do 4x + 5y - (x + 4y) = 3x + y which is the value of the bottom right rectangle. This means that the value of the bottom circle is 2x - y + 3x + y = 5x.
Answer:
Correct option: C.
Step-by-step explanation:
(Assuming the correct function is R(x) = 2x^2 + 3x + 5)
To find the input value that gives the value of R(x) = 19, we just need to use this output value (R(x) = 19) in the equation and then find the value of x:
Solving this quadratic function using the Bhaskara's formula (a = 2, b = 3 and c = -14), we have:
So looking at the options, the input to the function is x = 2
Correct option: C.
Answer:
x=31

Answer:
3/10 x 100 = 30.00
Step-by-step explanation:
Three tenths written as a fraction is 3/10. You can also write it as a decimal by simply dividing 3 by 10 which is 0.30.
If you multiply 0.30 with 100 you will see that you will get 30
