The answer is -27/64
I got this because when you multiply fractions you multiply straight across.

The sum of the squares of 2 consecutive negative integers is 41. What are the numbers? Which of the following equations is the r
VARVARA [1.3K]
Answer:
The two numbers are -5 and -4

Explanation:
Assume that the first number is x and that the second number is x+1.
We know that the sum of their squares is 41. This means that:
x² + (x+1)² = 41

We will expand the brackets and factorize to get the value of x as follows:
x² + (x+1)² = 41
x² + x² + 2x + 1 = 41
2x² + 2x + 1 - 41 = 0
2x² + 2x - 40 = 0
We can divide all terms by 2 to simplify the equation:
x² + x - 20 = 0 ..........> equation required in part II

Now, we can factorize this equation to get the values of x:
x² + x - 20 = 0
(x-4)(x+5) = 0
either x = 4 .........> rejected because we know that x should be negative
or x = -5 ...........> accepted

Based on the above calculations, the two numbers are -5 and -4

Hope this helps :)

the value of y is directly proportional to the value of x. if y=35 when x=140,what is the value of y when x=70
Goryan [66]
Y = kx, where k is the constant of proportionality.

We need to find k as our first step.

35 = k140

35/140 = k

1/4 = k

We can now find y when x = 70.

y = kx

y = (1/4)(70)

y = 70/4

This fraction can be simplified or reduced more.

The number 2 is the GCF of 70 and 4.

70 ÷ 2 = 35

4 ÷ 2 = 2

Answer:

y = 35/2
