Answer:
Step-by-step explanation:
Givens
x + y = 2
x - y = 6
Solution
Just add the two equations together. The y's will drop out.
x + y = 2
<u>x - y = 6 </u> Add
2x = 8 Divide by 2
2x/2 = 8/2 Combine
x = 4 Substitute x = 4 into the top equation
x + y = 2
4 + y = 2 Subtract 4 from both sides
4-4+y=2-4 Combine
y = - 2
Answer
x = 4
y = -2
Answer:
it would be A and C
Step-by-step explanation:
I used photo math and it used C as its answer, but answer A simplifies to answer C therefore meaning they are both your answers! I hope this helped!
Answer:
<u>The correct answer is C. 1.6</u>
Step-by-step explanation:
Let's recall that e or Euler's number is a mathematical constant that is the base of the natural logarithm, in other words, the unique number whose natural logarithm is equal to one. The value of e is approximately 2.71828.
Now, replacing e, we have:
2.71828∧(1/2) = √2.71828 = 1.6 (Rounding to one decimal place)
<u>The correct answer is C. 1.6</u>
