We re-write the system of equations by using the fact that we need the y-values to be the same, so we equal them:
- 10 x + 7/3 = - 10 x + 1/10
We notice then, as we try to solve for the one unknown left (x), that as we add 10 x on both sides of our new equation, all the terms in "x" go away, as shown below:
- 10 x + 10 x + 7/3 = - 10 x + 10 x + 1/10
combine like terms:
7/3 = 1/10
so we notice we have ended up with a ridiculous solution, a statement that tells us that 7/3 equals 1/10 which is mathematically a FALSE statement. Therefore, we conclude that the system has NO solutions, given that there are no possible x or y values that can ever produce a logical answer.
We select therefore the option No solution, among the list of answers.
Answer:
Answer is D. 104
Step-by-step explanation:
The √x from the number line is about 10.2. Or say less than 10.2. The number is also much greater than 10.1. If you square 10.2 to get the value of x;10.2² = 104.04So, the approximate value of x is 104.
Because the number is even, then the number of possible combinations will be: 110/2 = 55 let's consider a simpler example, the number: 10, then we have: 10+0, 9+1, 8+2, 7+3, 6+4, which is equal to 10/2 =5 combinations. Note: We are not considering permutations between the elements of the sum therefore 10+0, 0+10 counts as one combination.
