1) xy = -4
2) x+y = 4
From (2), x = 4-y
Substitute into (1)
(4-y)y = -4
4y-y2 = -4
y2-4y-4 = 0
After using quadratic formula to solve this, you'll the values of y, which are 4.8284 and -0.8284 after rounding up.
If you use 4.8284 to substitude in (2) as y, your x value is -0.8284
Other if you use -0.8284, you'll get 4.8284
Therefore the two numbers are 4.828427125 and -0.828427124
They are: 11*11 = 121
103 is already prime.
Numbers that are reciprocals of each other are called "reciprocal pairs." For example, if you have a number ( x ), its reciprocal is ( \frac{1}{x} ). When two numbers are reciprocals, their product equals 1.
The number 65 can be expressed in multiplication in several ways, such as (1 \times 65), (5 \times 13), or (-5 \times -13). Each of these pairs of numbers multiplied together equals 65.
The simplest answer for two numbers is 1 and 121. The most popular would be 11x11 however.
The numbers are: 30 and 5
They are: 2*3*11 = 66
97 is a prime number - therefore the only answer is 97 & 1
1 x 871, 13 x 67.
51 and 2
They are: 11*11 = 121
times the numbers by each other.
103 is already prime.
Multiplicand times multiplier equals product.
5 times 99 equals 495. There are several other answers.
Each of these factor pairs (multiply the numbers in parentheses) equals 106: (1, 106) (2, 53)
Divide the numbers that are diagonal from each other, but there are times when this does not work.
