Answer:

Yes

Step-by-step explanation:

Because since it tells you that x>7 and also it tells you if 7.1 is a solution. So what you need to do is plug in 7.1 instead of x and see if it's true or not. So is 7.1 greater than 7. Well yes it is and that makes it a solution. Hope this helps. Ask me any question if you need help with anything else. :)

Over a period of five days, the average time of a commuter train trip from one town to the city was 77 minutes. One trip was 71
OverLord2011 [107]
Average time of a commuter train trip from one town to the city = 77 minutes
Time taken by 1 trip = 71 minutes
Time taken by another trip = 74 minutes
Time taken by 3rd and 4th trip each = 78 minutes
Let us assume the time taken during the 5th trip = x
Then
(71 + 74 + 78 +78 +x)/5 = 77
301 + x = 77 * 5
301 + x = 385
x = 385 - 301
   = 84 minutes
So the length of the fifth trip was 84 minutes. I hope the procedure is clear enough for you to understand.

Write an equation of the line that passeg through (8, 1) and is perpendicular to the line 2y + 4x = 12
RUDIKE [14]

Answer:

y=1/2x-3

Step-by-step explanation:

First, let's put the line into slope intercept form

2y+4x=12

subtract 4x from both sides

2y=-4x+12

divide by 2

y=-2x+6

the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:

-2m=-1

divide by -2

m=1/2

so the slope of the perpendicular line is 1/2

here is the new line so far:

y=1/2x+b (b is a place holder)

now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation

1=1/2(8)+b

1=4+b

subtract 4 from both sides

-3=b

so the line is y=1/2x-3

Hope this helps!

Will mark brainliest...I need help!
Tasya [4]

Answer:

(- 3, - 13 ) and (8, 1 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Both equations are in vertex form

(8)

y = 5(x + 3)² - 13

with vertex = (h, k) = (- 3, - 13 )

(9)

y = (x - 8)² + 1

with vertex = (h, k) = (8, 1 )
