Answer:
Step-by-step explanation:
1)
First we add what we know for y into the second equation.
5x - 4(x +2)= -3
From there, we simplify it
5x-4x-8= -3
x-8=-3
Now we get the x on its own
x=5
and now we add x=5 into the first equation that we had and simplify to find y
y=5+2
y=7
So the answer is x=5, y=7 or (5,7)
2)
For this one we do the same thing as with 1.
Add what we know for y (bottom equation) to the top equation
3x-8(x-8)=24
Now we simplify
3x-8x+64=24
-5x+64=24
And now solve for X
-5x=-40
x=8
And then substitute x=8 to find y
y=8=8
y=0
So the answer is x=8, y=0 or (8,0)
Answer:
( C ) 20 inch
Step-by-step explanation:
AB=28 inch ( given )
AP=26 inch ( given )
since that xy bisects and its perpendicular to AB and CD
then AX=48/2 = 24 inch
so by using Pythagoras theorem
then 26 squared - 24 squared = 10 inch
so XD+YD= 10 +10 =20 inch
