There's no such thing as parallel or perpendicular "to a point". A problem like that
will always want the new line to be parallel or perpendicular to another <em><u>line</u></em>.
-- If the new line is parallel to the given line, then they have the <em><u>same</u></em> slope.
-- If the new line is perpendicular to the the given line, then the slope of the
new line is [ <em><u>1 / slope of the given line</u></em> ].
In either case, you now have the slope of the new line and a point on it.
From there, you should have no trouble finding its equation.
The answer is C because when you have similar radicals, you subtract the whole numbers. In this case 3 square root of 2 minus square root of 2, is doing 3 - 1 = 2.
2 square root of 2
Answer:
x=-4 y=5
Step-by-step explanation:
3×(16-4y)+4y=8
48-12y+4y=8
-8y=-40
y=5
x=16-4×5
x=-4
Answer:
He average for this semester so far is 81 points.
Step-by-step explanation:
Since his score is 10% lower this semester than last semester, then he present score is 100% from the prior semester minus 10%, which equals to 90% of the previous semester. In order to calculate that percentage we can use a rule of three as shown below:
90 points -> 100%
x points -> 90%
100*x = 90*90
x = 8100/100 = 81
He average for this semester so far is 81 points.
