Answer:
1 , 29/11
Step-by-step explanation:
3x+y = 10 ....(1)
2x² +y² = 19 ....(2)
3x+y= 10
y = 10-3x
substituting the value of y in 2nd equation
2x² + y² = 19
2x² + (10-3x)² = 19
2x² + 100 + 9x² - 60x -19 = 0
11x² - 60x +81 = 0
11x² - 33x - 27x + 81 = 0
11x( x-3) - 27(x-3) = 0
(x-3)(11x-27) = 0
x = 3, 27/11
substituting x value on first equation
x= 3 x= 27/11
y= 10-3(3) y= 10 - 81/11
= 10-9 = (110-81)/11
= 1 = 29/11

The rule is adding 5 if we say n is 2 then nth term is
n + 5(or so I hope )
<h3>
Answer: Choice B) -t+7</h3>
Explanation
The like terms are ones that have the same variable in them, or that dont have a variable at all attached. One pair of like terms is t and -2t, which combine to t+(-2t) = t-2t = -t
The other pair of like terms are 4 and 3 which add to 7
So t+4+3-2t simplifies fully to -t+7, which is the same as 7+(-t) = 7-t
We cannot simplify any further from here as the 7 and -t are not like terms.
