Answer:
the measures of the three angles: x=18°, y= 68°, z=. 94°
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
Comparing the two functions, you see that
... g(x) = f(x+7) +9
When x is replaced by x+7, the graph is shifted left 7 units.
When f(x) is replaced by f(x)+9, the graph is shifted up 9 units.
The transformations of f(x) are
- shift left 7 units
- shift up 9 units
