1.57, divide two times pi (3.14)
Answer:
(10, 14)
Step-by-step explanation:
To solve this system let's use substitution:
Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:
3(24 - y) + 5y = 100
Performing the indicated multiplication, we get:
72 - 3y + 5y = 100
Combining like terms results in 72 - 100 = -2y, or -28 = -2y
Thus, y must be 14.
If y = 14, then the first equation tells us that x = 10.
Check: Is this true? 3(10) + 5(14) = 100 YES
The solution is (10, 14).
What was it about the questions on the best that you were supposed to compare to this solution?
Answer:
The function is negative for all real values of x where
-6 < x < -2.
Step-by-step explanation:
f(x) = (x +2)(x + 6)
x + 2 = 0 or x + 6 = 0
x = -2 or x = -6
After graphing the function is negative between -6 < x < -2
