Answer:
a
Step-by-step explanation:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
There is no difference. Both mean the same measurement except that 1.050 is presented in 4 significant figure and 1.05 in 3 significant figure.
82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
A. y=2x
because slope-intercept form is y=mx+b. m= slope & b= y-int. The y-int is at the origin, so therefore y=0. The slope is 2, so therefore the answer is y=2x
