Answer:
y = x + 7
y = (-x) + 2
X + 7 = (-x) + 2
X + X = 2 - 7
2x = (-5)
<h3>x = (-5)/2 </h3>
Putting the value of X in equation
Y = (-5/2) + 7
Y = (-5)/2 + 7/1
Equalising the denominator by Taking LCM
Y = (-5)/2 +14/2
Y = ( -5 +14)/2
<h3>Y = (9)/2 </h3>
Answer:
i think you might have to round or something
Step-by-step explanation:
Answer:
Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).
Step-by-step explanation:
The difference of two squares is a special form. a² - b² = (a+b)(a-b).
But, the sum of two squares is prime. a²+ b² cannot be factored.
Answer:
Step-by-step explanation:
the answer is unknown because there is no answer to that question and if there was it would be odd an would not make sence so that is a true of false question
Since 3=30/10, (30+1)/10=31/10. 31s/10=(30+1)/5 ( we get 30 because 5*6=30) = 31/5. Multiplying both sides by 10, we get 31s=62 (since 5 is a factor of 10, we can do 10/5 =2 and multiply 2 by 31). Dividing both sides by 31, we get s =2
