There are 2 order pairs there (6,-4),(-2,4)
find the midpoint using the formula
(x1+x2)/2 , (y1+y2)/2
x=6 and -2
y=-4 and 4
(6+2)/2 , (-4+4)/2
8/2 ,0/2
the midpoint is (4,0) A
It is D because us the given equation all you do is plug in the x values given on the chart
Hi there!
x - 3y = 9
x = 9 + 3y
-4x + y = 8
-4(9+3y) + y = 8
-36 - 12y + y = 8
-36 - 11y = 8
-11y = 44
-y = 4
y = -4
x - 3y = 9
x - 3(-4) = 9
x + 12 = 9
x = 21
So, your answers are y = -4 and x = 21.
Hope this helps!
Answer:
Your answer to the fig. would be 14cm^2.
Adding area of both rectangles,
(8+6) cm^2
= 14cm^2
Hope it helps!!
Answer:
y=9
Step-by-step explanation:
First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction
y/3 -4= -1
y/3= 3
Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.
y/3=3
y=9
Thus we get that the value for y is 9.
Hope this helped!
Btw you're very pretty! <3
