Answer:
only A is correct
Step-by-step explanation:
To get the equation of the given line, we just have to see if the point given fits into any of the equation
The given point is (15,3)
a) y = 1/5x = 1/5 * 15 = 3
This is correct
b) y = -5(-75) = -375; this is not correct
c) y = 3x
y = 3(15) = 45
This is not correct
d) y = 15x
y = 15(15) = 225
This is incorrect
e) y = -1/5x
y = -1/5 * 15 = -3
This is incorrect
f) y = 5x
y = 5(15) = 75
This is also incorrect
i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.
So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL
ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the steps
A person can make 100 using the digit 9 four times in an equation.<span> The equation for this math problem is: 99 + (9 / 9) = 100. This solution works because 9 divided by 9 equals 1, and 99 plus 1 equals 100</span>
(x−a)(x−b)
=(x+−a)(x+−b)
=(x)(x)+(x)(−b)+(−a)(x)+(−a)(−b)
=x2−bx−ax+ab
