Answer:
So the x-intercept is (9,0) and the y-intercept is (0,-3).
So I'm going to graph both points and connect them with a straight-edge.
Step-by-step explanation:
I would graph this using it's x- and y-intercepts.
To find the x-intercept, set y=0.
-3x+9(0)=-27
-3x+0=-27
-3x=-27
Divide both sides by -3:
x=9
To find the y-intercept, set x=0:
-3(0)+9y=-27
0 +9y=-27
9y=-27
Divide both sides by 9:
y=-3
So the x-intercept is (9,0) and the y-intercept is (0,-3).
So I'm going to graph both points and connect them with a straight-edge.
Answer:
The error mentioned is a systematic error.
Step-by-step explanation:
The glass beads used for mass measurements was noticed to be significantly smaller than those used for volume measurements.
The formula for density is = .
So if we try to experimentally determine the value of density of glass then the beads for measuring the mass are much smaller than the beads for measuring volume.Thus in this case we can see that the density measured will actually be less than the actual density of glass.
However since this error can be seen and quantified and corrected it is not a random error, but it is a systematic error.
