Answer:
Take 16.28 x 8%. You get $1.30 so add 16.28 to 1.30 to get 19.58
Step-by-step explanation:
3x=y
X+Y=20
5=x and 15=y are the answer. You can use elimination or substitution or guess and check!
F(-1)=2
F(2)=-1
F(3)=-3
The f(x) part is the input and the stuff after is the output
A rhombus is quadrilateral where all 4 sides are of equal length. Thus
5x + 2 = 2x + 12
3x = 10
x = 10/3
substituting x into either expression, yields
56/3
therefore side AB = 56/3
1/4x+4/4x = -6/2x+1/2x
5/4x = -5/2x
x=0
