How do I find slope intercept for a line that passes through (4,-4) with a slope of -1

Mathematics

Answer:

y = -x

Step-by-step explanation:

Use the equation:

y = mx + b

where m is the slope and b is the y-intercept.

In this case, there is no y intercept, as we can see by manipulating the point-slope equation:

y + 4 = -1(x + 4)

y = -x + 0

So, the equation for this line is y = -x.

Y=-1x
or
y=-1x + 0

Considering you already have the slope & a point you end up having

Y = mx + b

-4 which is your Y so

-4=mx + b

M is your slope so

-4=-1(x) + b

Your x is 4 so

-4= -1(4) + b

B is your y intercept but because -4 = -1 times 4 your b is zero

Assume that P(E) = 0.471 and P(F) = 0.595. If E and F are independent, find P(E and F)
dsp73

The value of the probability P(E and F) is 0.2802

<h3>Independent probability</h3>

Events are known to be independent if the occurrence of one does not affect the other.

Given the following parameters

P (E) =0.471

P(F) = 0.595

If E and F are independent, then;

P(E and F) = P(E)P(F)

P(E and F)  = 0.471 * 0.595
P(E and F)  = 0.2802

Hence the value of the probability P(E and F) is 0.2802

#7. What are the values/ how do I do it
Tasya [4]

Answer:

x =2

SK = 21

KY = 13

SY = 34

Step-by-step explanation:

we can see from the picture the following:

SK + KY = SY  equation 1

SK=13x-5    equation 2

KY = 2x+9    equation 3

SY = 36-x     equation 4

using equation 2, equation 3 and equation 4 in equation 1 we have:

13x - 5 +  2x + 9 = 36-x  

15x +4 = 36 - x

15x +x = 36-4

16x = 32

x = 32/16

x= 2

using x as 2 we evaluate it in equation 2, equation 3 and equation 4:

SK=13(2)-5 = 21

KY= 2(2) +9 = 13

SY = 36-2 = 34

11 th term of the following geometric sequence.<br> 10,50,250,1250
Natasha2012 [34]

Answer:

97,656,250

Step-by-step explanation:

The first term, a(1), is 10.  The next is 5 times greater.  And so on.  Thus, the common ratio is 5, and the general formula for this sequence is

a(n) = a(1)*5^(n -1).

Therefore,

a(11) = 10*5^(11 - 1) = 10*5^10  =  97,656,250

What are the dimensions of the container holding a 1" x 1" x 1" cube
Allushta [10]
Each dimension has to be 1" or bigger, otherwise the cube won't fit. _________ WAIT ! The container doesn't have to be rectangular, and that opens up a lot more possibilities. The smallest possible rectangular container is a little tiny cardboard cube whose dimensions are all 1", just like the contents. But you could also keep it in a container shaped like a pyramid, a cylinder, an egg, etc. If the container is a sphere, then its radius has to be at least 0.866 inch.
