Answer:
(74/9,274/9)
Step-by-step explanation:
You have
x-5y=4 and
y=2x+14
so we subsitute y in the first equation
x-5(2x+14)=4
x-10x-70=4
-9x=74
x=74/9
so y=2(74/9)+14
y=148/9+14
y=274/9
so the oredered pair is
(74/9,274/9)
widest to narrowest: y=3/2x2, y= -1/2x2, y= 1/4x2
Answer:
37.5
Step-by-step explanation:
split in the middle, 5×5=25/2=12.5
12.5= triangle
5×5=25
25=square
