A
Step-by-step explanation:
Answer:
3 and - 4
Step-by-step explanation:
Let
The first number be "x", and
The second number be "y"
The sum of the 2 numbers is -1, so we can write:
x + y = -1
or
x = -1 - y
Twice the first and 4 times second SUMMED, gives us -10, so we can write:
2x + 4y = -10
Now, we put 1st equation in 2nd and find y first:

Now, finding x:
x = -1 - y
x = -1 -(-4)
x = -1 + 4
x = 3
So, the two number are:
3 and - 4
So, we are given the y intercept, and since we know c is the same as the y value of the y intercept, we know that c=15.
From there we can pick any two of the points given to us to find our a and b.
Let's use (4,17) and (8,23) becase they are whole numbers.

So, with b=0, we can plug it back into the first equation to get:
So our quadratic is 
Answer:
2 and 8
1 and 3
Step-by-step explanation:
statement a+b < a*b
-2 + -8 < -2 * -8 => -10 < 16 TRUE
-1 + -3 < -1 * -3 => -4 < 3 TRUE
1+3 < 1*3 => 4 < 3 FALSE
2 + 8 < 2 * 8 => 10 < 16 FALSE
He reads 1/11 book in 2/5 hour.
A whole book is 11/11 of a book.
Multiply by 11.
He reads 11/11 book in 11 * 2/5 hour.
He reads 1 book in 22/5 hour.
22/5 hour = 4.4 hour = 4 hours and 24 minutes
