Find the slope and y-intercept of the line that is perpendicular to
y= —1/3x + 5 and passes through the point (—3, —7)

The line is

Step-by-step explanation:

For one line to be perpendicular to the other, the lines must have negative reciprocal slopes. The slope in the given function is -1/3, so the slope of the other line is 3

We're given an ordered pair, so we can use the equation to solve for the y intercept

The line is

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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
