The line which represents the equation x = 5 is a vertical line that passes through any point hax x-coordinate of 5

Then the perpendicular line to this line must be a horizontal line

The equation of any horizontal line is y = b, where

b is the y-coordinate of any point that lies on the line

Since the line passes through the point (-2, 2), then

b = 2

Then the equation of the line is

y = 2

what is the answers?? please lmk i need the hours of Monday to Tuesday and how many hours did the Jacobys did in all ,please exp

SSSSS [86.1K]

Answer:

Step-by-step explanation:

A. Hours driving on monday= $5\frac{3}{4}$ =23/4 hours (5 x 4 +3)

Hours driving on tuesday= $4\frac{3}{4}$ =19/4 hours (4 x 4 +3)

Total hours = 23/4 + 19/4 = 42/4 = $10\frac{2}{4}$ hours

B. Total hours driving = Hours driving on (Monday + tuesday + wednesday + thursday)

Hours driving on wednesday= $2\frac{1}{4}$ =9/4 hours (2 x 4 +1)

Hours driving on thursday= $6\frac{3}{4}$ =27/4 hours (6 x 4 +3)

Total hours driving = 23/4 + 19/4 + 9/4 +27/4 = 78/4 = $19\frac{2}{4}$ hours

7c + 7a - 7r + 8m + 2y=31<br><br>solve for c a r m and y

Blizzard [7]

For this case we have the following equation:

$7c + 7a-7r + 8m + 2y = 31$

We solve for c:

We pass the terms that do not contain "c" to the other side of the equation by changing signs:

$7c = 31-7a + 7r-8m-2y$

We divide by 7 on both sides of the equation:

$c = \frac {31-7a + 7r-8m-2y} {7}$

We solve for "a":

We pass the terms that do not contain "a" to the other side of the equation by changing signs:

$7a = 31-7c + 7r-8m-2y$

We divide by 7 on both sides of the equation:

$a = \frac {31-7c + 7r-8m-2y} {7}$

We solve for r:

We pass the terms that do not contain "r" to the other side of the equation by changing signs:

$-7r = 31-7c-7a-8m-2y$

We multiply by -1 on both sides:

$7r = 7c + 7a + 8m + 2y-31$

We divide by 7 on both sides of the equation:

$r = \frac {7c + 7a + 8m + 2y-31} {7}$

We solve for m:

We pass the terms that do not contain "m" to the other side of the equation by changing signs:

$7c + 7a-7r + 8m + 2y = 31\\8m = 31-7c-7a + 7r-2y$

We divide by 7 on both sides of the equation:

$m = \frac {31-7c-7a + 7r-2y} {8}$

We solve for y:

We pass the terms that do not contain "y" to the other side of the equation by changing signs:

$2y=31-7c-7a+7r-8m$

We divide by 2 on both sides of the equation:

$y=\frac{31-7c-7a+7r-8m}{2}$

Answer:

$c = \frac {31-7a + 7r-8m-2y} {7}$

$a = \frac {31-7c + 7r-8m-2y} {7}$

$r = \frac {7c + 7a + 8m + 2y-31} {7}$

$m = \frac {31-7c-7a + 7r-2y} {8}$

$y=\frac{31-7c-7a+7r-8m}{2}$

An orbiting satellite has seven solar cells, which function independently of each other. During a mission, each cell fails with

Dmitrij [34]

The probability of each cell not failing is 1.0 - 0.3 = 0.7.
The probability of all 7 cells not failing during a mission is given by:
$P(7\ cells\ do\ not\ fail)=0.7^{7}=0.082\ or\ 8.2\ percent$
