PLEASE HELPPP!!!!!! Write an equation of the line passing through point P that is perpendicular to the given line.

ArbitrLikvidat [17]

Answer:(d): y=ax+b (a≠0); (d1)y=-4x+13

because of (d)⊥(d1) --> a.(-4)=-1 --> a= $\frac{1}{4}$

(d): y= $\frac{1}{4}x$ +b. (d) pass through P(-1;-2) so we have

-2=(1/4).(-1)+b ---> b= $\frac{-7}{4}$

(d) y= $\frac{1}{4}x+ \frac{-7}{4}$

I am confused. what is 5r– 7 = 2r+ 14

Vlada [557]

Answer:

r=7

Step-by-step explanation:

5r-7=2r+14

add sevento both sides

5r=2r+21

Subtract 2r from both sides.

3r=21

divide both sides by 3

r=7

This box plot shows information about the marks scored in a test.

aliina [53]

Since 120 students gained less than 70, and 70 is the upper quartile, 120 people are in the 75% of all the students so we need to find the total number of students.
we need to multiply 0.75 (75%) by something to get 120. which is 160 (the total number of all students).
and since 48 is the median score, find 50% of 160 which is 80!
hope this helps :)

Answer:

Step-by-step explanation:

When angles are between the parallel lines, they are called interior. If they are both on the same side of the transversal, they are "same-side interior."

If angles are on opposite sides of the transversal, they are exterior.

If angles are in the same direction from the intersection point, they are corresponding.

Angles in opposite directions from the point of intersection are vertical angles.

same-side interior: {3, 5} and {4, 6}. (supplementary)

same-side exterior: {1, 7} and {2, 8}. (supplementary)

alternate interior: {3, 6} and {4, 5}. (congruent)

alternate exterior: {1, 8} and {2, 7}. (congruent)

corresponding: {1, 5}, {2, 6}, {3, 7}, {4, 8}. (congruent)

vertical: {1, 4}, {2, 3}, {5, 8}, {6, 7}. (congruent)

Angles 6 and 4 are same-side interior angles; their sum is 180°.

Find the distance between the points given. (0.5) and (-5, 0)

Andrew [12]

Answer:

I cant help unless i have workable units (0.5) is not a point

but im guessing that you were trying to say (0,5) in which case its

7.07106781187

its a triangle

5 on one side

5 on the other

solve for the hypotenuse

hypotenuse = $\sqrt{50}$

hypotenuse = 7.07106781187

I hope this helps!
