marusya05 [52]3 years ago
8 0

Answer:

The answer is D) (-1, -1)

Step-by-step explanation:

In order to find which answer is a solution, you have to put the ordered pair in for their given variables. If it produces a true statement, then it is a solution. In this case, D is the only one that produces a true statement.

2x + y > -4

2(-1) + (-1) > -4

-2 - 1 > -4

-3 > -4 (TRUE)

a line intercects the points (-22,-14) and (-18,-12). what is the slope intercept equation for this line?
Nadya [2.5K]

Answer:

y = \frac{1}{2} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 22, - 14) and (x₂, y₂ ) = (- 18, - 12)

m = \frac{-12+14}{-18+22}  = \frac{2}{4} = \frac{1}{2}

y = \frac{1}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (- 22, - 14), then

- 14 = - 11 + c ⇒ c = - 14 + 11 = - 3

y = \frac{1}{2} x - 3 ← in slope- intercept form

Cargo ships arrive at a loading dock at a rate of 2 per day. The dock has the capability of handling 3 arrivals per day. How man
Vsevolod [243]

Answer:

4 days

Step-by-step explanation:

We need to use the probability functions of each of the intervals to know the Probability number and then use it in the expected value.

P(x>3 cargo ships) = 1-P(x<=3)

P(x>3) = 1-P(x<=3)

P(x>3) = 1-[P(x=0)+P(x=1)+P(x=2)+P(x=3)]

P(x>3) = 1 - [\frac{e^{-2}2^0}{01}+\frac{e^{-2}2^1}{11}+\frac{e^{-2}2^2}{21}+\frac{e^{-3}2^3}{31}]

P(x>3) = 1- [0.1353(1+2+2+1.33)]

P(x>3) = 1-0.856

P(x>3) = 0.1431

Als n=30, expected number is

E(x) =30*P(x>3)

E(x) = 30*0.1431

E(x) = 4.293

I expect 4.293 or 4 days per month the block being unable to hanlde all arriving ships

Srry I just don’t understand 12 points
marshall27 [118]

Answer:

y = -2x - 3

Step-by-step explanation:

Please look carefully at this graph.  There are two red dots on the graph.  The x- and y-coordinates of one are (-5,7) and those of the other are (0,-3).

Now as we move to the right, from (-5,7) to (0,-3), x increases by 5 and y decreases by 10 (note that 7-10 is -3).  Thus, the slope of this line is

m = rise / run = -10/5, or m = -2.

Then the equation of this line, in point-slope form, is

y-7 = -2(x-[-5])x, or y-7 = -2(x+5).  This is in point-slope form.

If you'd like to have it in slope-intercept form, manipulate y-7 = -2(x+5) as follows:  (a) add 7 to both sides, obtaining y = -2(x+5) + 7, and (b) perform the indicated multiplication:  y = -2x - 10 + 7, or y = -2x - 3.
