Answer: X = -24 Y = 66
Step-by-step explanation:
5(-6) = -30
X = 6 - 30 = -24
Y = 42 + 24 = 66

Steps to simplifying fractions
Find the GCD (or HCF) of numerator and denominator
GCD of 216 and 270 is 54
Divide both the numerator and denominator by the GCD
216 ÷ 54
270 ÷ 54

Answer:
Time t = 2 seconds
It will reach the maximum height after 2 seconds
Completed question;
Amir stands on a balcony and throws a ball to his dog who is at ground level. The ball's height, in meters above the ground, after t seconds that Amir has thrown the ball is given by:
H (t) = -(t-2)^2+9
many seconds after being thrown will the ball reach its maximum height?
Step-by-step explanation:
The equation of the height!
h(t) = -(t-2)^2 + 9 = -(t^2 -4t +4) + 9
h(t) = -t^2 +4t -4+9 
h(t) = -t^2 + 4t +5
The maximum height is at dh/dt = 0
dh/dt = -2t +4 = 0
2t = 4
t = 4/2 = 2
Time t = 2 seconds
It will reach the maximum height after 2 seconds
 
        
             
        
        
        
5x + 3. You can also synthetically divide because of the linear divisor
 
        
        
        
The direct answer to your question is: "No".
because in that equation, 'x' is not 120 or130.
Let's find out what 'x' actually is:
<u>3/5 x  =  52</u>
Multiply each side by  5 :      3x  =  260
Divide each side by  3 :       <em>  x  =  86 and 2/3 </em>
