Y varies directly as x: y=kx, k is a constant.
when x=7, y=21, so we know k=3
therefore, the equation is y=3x
The domain is going to be ur x values....the number of minutes
therefore, ur domain is : I know it is either A or C.....I am thinking C because it does not have to be a whole minute...it can be 1.5 minutes...so that would eliminate A. final answer is gonna be C
0.7% percent is the answer
You know slope intercept form is y=mx+b so just put in that form by:
Adding 4x to other side
2y=10+4x
Then divide by 2
Y=10/2 +4/2x
Simplify
Y=5+2x
I rearranged so x is first so your answer would be: y=2x+5
Answer:
triangle abd is isosceles triangle and triangle dbc is equilateral triangle.
opposite sides of equal angles are same. so, ad= bd
and bd is the side of equilateral triangle. so, bd=bc=dc
perimeter of quadrilateral = sum of all sides.
perimeter=11+8+8+8
perimeter =35
