Answer:
A. The product is equal to 743.
B. The product is less than 107.
C. The product is more than 647.
Step-by-step explanation:
If both sides of the fraction are equal it is equal, if the top is higher it is greater and if the bottom is greater then it is less. Btw I mean greater than the other side of the fraction.
Answer:
A
Step-by-step explanation:
The absolute value of -3 is 3, which is less than the absolute value of 9. And -3 is less than 9.
Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y
2y = 180-5x
Divide by 2
2y/2 = 180/2 -5x/2
y = 90 -5/2 x

Hello there.
First, assume the numbers such that they satisties both affirmations:
- The sum of the squares of two numbers is .
- The product of the two numbers is .
With these informations, we can set the following equations:
Multiply both sides of the second equation by a factor of :
Make
We can rewrite the expression on the left hand side using the binomial expansion in reverse: , such that:
The square of a number is equal to if and only if such number is equal to , thus:
Substituting that information from in , we get:
Calculate the square root on both sides of the equation:
Once again with the information in , we have that:
The set of solutions of that satisfies both affirmations is:
This is the set we were looking for.
