Answer:
see below
Step-by-step explanation:
It is easiest to compare the equations when they are written in the same form.
The first set can be written in slope-intercept form.
y = 2x +7
y = 2x +7 . . . . add 2x
These equations are <em>identical</em>, so have infinitely many solutions.
__
The second set can be written in standard form.
y +4x = -5
y +4x = -10
These equations <em>differ only in their constant</em>, so have no solutions.
__
The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.
C because if it was constant then for day 3 the distance would be 65.4 instead of 64.8
Uhhh 0.3 or 1.2 lol hope this helps
Answer:
502.4
Step-by-step explanation:
Volume of a cylinder(formula)=πr2h
So pie is 3.14
3.14×4×4(radius2)×10
This is equal to 502.4
Hope it helped
