Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3
Step-by-step explanation:
the value of x is 20 that's it good luck
<h3>
Answer: K ' is at (1, 4)</h3>
Explanation:
Point K is located at (1, -4)
We use the rule that 
when reflecting over the x axis.
The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.
Therefore, K(1,-4) will move to K ' (1, 4)
I'm her first quiz she did better, this is going to be hard to explain but pay attention 92% as a decimal is 92/100 keep this in mind, then 27 out of 30 question we try to make 30 go into 100 but we know 30 can't go into 100 without a decimal so what we do is we change the decimal to 90 so for the 27 out of 30 it is now 81/90, now we need to change the denominator in 92/100 to 90 so we subtract 10 from the numerator and denominator to get 82/100 so compare the 2 decimals you got 81/90 and 82/90 and you find that 82/90 is bigger so she did better on the first quiz
