Write an euqation of a line that is perpendicular to y=1/2x+3 and passes through the point (10,-5)

Step-by-step explanation:

Slope of the perpendicular line = (-1)/(1/2) = -2.

y = -2x + c. When x = 10, y = -5.

=> (-5) = -2(10) + c, c = 15.

Hence the equation of the line is y = -2x + 15.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
