Y − 3 = (x + 4)

The given line passes through the points (−4, −3) and (4, 1).

What is the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (−4, 3)?

The first thing you have to do is find the slope of the line connecting these 2 points. Use the slope formula for that: m = y2-y1/x2-x1. We do this math:
m=1-(-3)/4-(-4) to get a slope of 1/2. We know that the line perpendicular to the one we have has to have a slope that is the opposite reciprocal of this slope which is -2. Write the equation of the line now using that slope of -2. You only have to use 1 of the coordinates to write the equation. Let's use (4,1) cuz I'm not a fan of negative numbers. y - y1 = m(x - x1) is the formula for the equation in point-slope form. y - 1 = -2(x - 4) is the equation. That is leaving it in point-slope form. If you simplify it to slope-intercept, or y = mx + b, it would look like this: y = -2x + 9

The scale for a map is 20 miles = 1/2 inch. The distance between two towns on the map is 3 3/4 inches. What is the actual distan

zubka84 [21]

Answer:

150 miles

Step-by-step explanation:

If 1/2 of an inch is 20 miles, we can assume that 1/4 of an inch is 10 miles, since half of 1/2 is 1/4 and 1/2 of 20 is 10.

Equipped with this information, we can divide 3 by 1/2 or multiply 3 by the reciprical, 2/1 to get how much we should multiply 20 by.

3*2=6

20*6=120

Then we can multiply 10 by 3 and add that on our answer, since there are still 3/4s left and 1/4=10 miles.

10*3=30

120+30=150

The actual distance is 150 miles.

Hope this helps!

Which biconditional is not a good definition?

Xelga [282]

The correct answers are:

A ray is a bisector of an angle if and only if it splits the angle into two angles; and
A) I can afford to buy a ticket.

Explanation:

For the first question, the first three answers are very specific and true:

A whole number is odd if it is not divisible by 2, and a number is not divisible by 2 if it is odd;
an angle is straight if its measure is 180 degrees, and the measure of an angle is 180 degrees if it is a straight angle;
a whole number is even if it is divisible by 2, and a number is divisible by 2 if it is even.

However, with the fourth choice, we are missing a key word in the definition. A ray is a bisector of an angle if and only if it splits the angle into two CONGRUENT angles. It is not just a ray that cuts an angle into two pieces, the pieces must be equal.

For the second question, the Law of Detachment says if our conditional "if p, then q" is true and p is true, then q must also be true.

For this question, "I can go to the concert if I can afford to buy a ticket" is true as well as "I can go to the concert." This means "I can afford to buy a ticket" must be true as well.
