1 answer:
77julia77 [94]3 years ago
6 0

Step-by-step explanation:

A(-2;1)

B (6;5)

(y-yA)/(yB-yA)= (x-xA)/(xB-xA)

(y-1)/4=(x+2)/8

8y-8=4x+8

8y=4x+16

y=½x+2 that is x-2y+4=0

Okay so, togo flies 30 miles in 3/5 of an hour with the wind.togo flies 30 miles in 5/6 of an hour against the wind. his rate of speed with the wind was 30 / (3/5) = 30*5/3 = 150/3 = 50 mph.his rate of speed against the wind was 30 / (5/6) = 30*6/5 = 6*6 = 36 mph.3/5 of an hour times 50 mph = 30 miles.
5/6 of an hour times 36 mph = 30 miles.mph looks good.
going he was with the wind.
his rate of speed then was the airplane speed plus the wind speed.coming back he was against the wind.his rate of speed then was the airplane speed minus the wind speed.-----50 mph = A + W36 mph = A - W-----looks like A + W - (A - W) should equal 50 - 36.removing parentheses, equation becomesA + W - A + W = 14.
combining like terms, the equation becomes2*W = 14.dividing both sides by 2, equation becomesW = 7.if W = 7, then A can be found as follows:50 = A + 7A = 43.likewise,36 = A - 7A = 43.since the airplane speed is the same, it looks like the answer is good.solving in the original equations, we get3/5 * (43 + 7) = 303/5 * 50- = 3030 = 30good.-----5/6 * (43 - 7) = 305/6 * 36 = 3030 = 30good.
answer is W = 7 and A = 43.

GIVING BRAINLEST!!!Joe and Tim observed two points, P and Q, on a number line. A number line is shown from negative 1 to positiv
Veronika [31]

Answer:

Step-by-step explanation:

P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

 an absolute value turns a negative number into a positive number

 so absolute value of  P located at -5/8 = 5/8

 this is the location of point Q

Joe said that the absolute values of the numbers represented by the two points are the same.

Find the length of a square whose area is 0.0084m​
TiliK225 [7]

Answer:

.091651514m

Step-by-step explanation:

The area of a square is found by

A = s^2 where s is the side length

.0084 = s^2

Take the square root of each side

\sqrt{.0084} = \sqrt{s^2}

.091651514 = s
