Answer:
Q = -6
Step-by-step explanation:
To find the answer to this, you first must multiply the first function by 2:
2 x (x - 3y = 4)
2x - 6y = 8
Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:
2x - 6y = 8
2x + Qy = 8
The 2x's cancel out, and then remove the equals and the 8:
-6y = Qy
<h3>So Q must be -6</h3>

Answer: 1. x= -12 2. x= 12
Step-by-step explanation:
1. 5(+3)=−45
5x+15−15=−45−15
5x= -60
5x/5 = -60/5
x = -60/5
x= -12
2. 1x/2−4=2
x/2 -4=22−4+4=2+4
/2=6
2⋅2=2⋅6
x=2⋅6
x= 12
24.69 x 12 = 296.28
296.28 x 1.06 = 314.06
With tax and everything, the total bill rounds up to $314.06. Hope this helped!
Answer:
y+2-x=0
Step-by-step explanation:
Here,
(-3,-5)=(x1,y1)
(3,1)=(x2,y2)
Slope(m)=y2-y1/x2-x1
=1-(-5)/3-(-3)
=1+5/3+3
=6/6
=1
Mid point=(x1+x2/2 , y1+y2/2)
=(-3+3/2 , -5+1/2)
=(0/2 , -4/2)
=(0 , -2)
Now, (0,-2)=(x1,y1)
Equation:
y-y1=m(x-x1)
y+2=1(x-0)
y+2=1x
y+2-x=0 is the required equation.
