Answer:
a) 11
b) 9
Step-by-step explanation:
a) x=4 y=3
2x+y
2(4)+(3)
8+3
=11
b) a=-2 b=5
a^2+b
(-2)^2+(5)
4+5
=9
Answer:
A) JK and LM will be parallel to each other.
Step-by-step explanation:
On reflection on line the x co-ordinate changes with y co-ordinate and y co-ordinate changes with x co-ordinate
Points on line EF
On reflection of this line on the new points we get for line JK are
Points on line GH
On reflection on y=x line the new points we get for line LM are
Slope of line JK
Slope of line LM
For two line to be parallel, their slopes will be same.
Since slopes of lines JK and LM are same therefore we can say that these are parallel to each other.
6(x+2)
you just factor 6 from the expression
hope this helps
72*12 = 2*2*2*2*2*3*3*3 = 2^5*3^3
It would be: 4 / 2/5
We can re-write it as:
4 * 5/2
= 20/2
= 10
In short, Your Answer would be: 10
Hope this helps!
