Which equation am I looking at
Answer: 50,2
Explanation:
Let’s call the two numbers a and b.
The sum of them is 52 so a+b=52
The product of them is 100 so ab=100
We now have a system which we can solve in a variety of ways.
My way:
ab=100; b=100/a
a+b=52; a+(100/a)=52; (a^2/a)+(100/a)=52; (a^2+100)/a=52
a^2+100=52a
a^2-52a+100=0
This is now a quadratic which we can solve by factoring. We can use the factors -50 and -2
Therefore, a^2-52a+100=
(a-50)(a-2) or a equals 2 OR 50
Therefore, b=(100/2) or b=(100/50) so b equals 50 OR 2 respectively.
The answers are 50 and 2
-18v^2 + 23v^2 =
In order to find the solution to this problem we are gonna add like terms.
-18v^2 + 23v^2
= 5v^2
A negative plus a positive results to a positive
Answer:
4^10
Step-by-step explanation:
4^2 * 4^8
We know that a^b * a^c = a^(b+c)
4^2 * 4^8 = 4^(2+8) = 4^10
Answer:
-2/4
Step-by-step explanation:
-4/5 × 10/16
= 2/-4
= -2/4
