$x\leq\frac{2}{5}$

Step-by-step explanation:

So starting from the beginning...

$3x+3\leq -2x+5$

Subtract the 3 from both side and it will look like...

$3x\leq-2x+2$

Then add 2x from both sides and it will look like...

$5x\leq 2$

Finally divide by 5 to both sides and it will look like...

$x\leq \frac{2}{5}$

Type the slope intercept equation of the line tjat passes through the points 2,0and 0,-2

Sedbober [7]

Hey there!

The slope-intercept equation is written as follows:

y = mx + b

Where m is the slope and b is the y-intercept. Therefore, we need both to write the form in slope-intercept. First, we'll find the slope.

To find the slope, we can use the slope given two points formula, which is defined as:

y2-y1/x2-x1

Plug in values (2,0) and (0, -2):

-2-0/0-2 = -2/-2 = 1

Now, we can use one of the points we have and our slope to set it equal to y, plug in x and the slope, and solve for b. We'll use (2, 0). We have:

0 = 1(2) + b

Remember, 0 is the y, 1 is the slope, and 2 is the x.

0 = 2 + b

-2 = b

Therefore, our equation is:

y = x - 2

Hope this helps!

A system consists of two components C1 and C2, each of which must be operative in order for the overall system to function. Let

hram777 [196]

Answer:

The reliability of the first system to work is 0.72 whereas the reliability of the second system to work is 0.98.As the reliability of the second system is more than the first one so the second system is more reliable.

Step-by-step explanation:

For first system as given in the attached diagram gives,

$P(W_1W_2)=P(W_1) \times P(W_2)$

As the systems are independent.

The given data indicates that

$P(W_1)$ is given as 0.9
$P(W_2)$ is given as 0.8

Now the probability of the system is given as

$P(W_1W_2)=P(W_1) \times P(W_2)\\P(W_1W_2)=0.9 \times 0.8\\P(W_1W_2)=0.72$

So the reliability of the first system to work is 0.72.

For the second system is given as

$P(W_1W_2)=1-P(W_1'W_2')$

Where

$P(W_1'W_2')$ is the probability where both of the systems does not work. this is calculated as

$P(W_1'W_2')=P(W_1') \times P(W_2')\\P(W_1'W_2')=(1-P(W_1)) \times (1-P(W_2))\\P(W_1'W_2')=(1-0.9) \times (1-0.8)\\P(W_1'W_2')=(0.1) \times (0.2)\\P(W_1'W_2')=0.02$

So now the probability of the second system is given as

$P(W_1W_2)=1-P(W_1'W_2')\\P(W_1W_2)=1-0.02\\P(W_1W_2)=0.98$

So the reliability of the second system to work is 0.98.

As the reliability of the second system is more than the first one so the second system is more reliable.
