Answer:
(-1, -1) Let me know if the explanation didn't make sense.
Step-by-step explanation:
If we graph the three points we can see what looks like a quadrilateral's upper right portion, so we need a point in the lower left. This means M is only connected to N here and P is only connected to N. So we want to find the slope of these two lines.
MN is easy since their y values are the same, the slope is 0.
NP we just use the slope formula so (y2-y1)/(x2-x1) = (-1-3)/(5-4) = -4.
So now we want a line from point M with a slope of -4 to intersect with a line from point P with a slope of 0. To find these lines weuse point slope form for those two points. The formula for point slope form is y - y1 = m(x-x1)
y-3 = -4(x+2) -> y = -4x-5
y+1 = 0(x-5) -> y = -1
So now we want these two to intersect. We just set them equal to each other.
-1 = -4x -5 -> -1 = x
So this gives us our x value. Now we can plug that into either function to find the y value. This is super easy of we use y = -1 because all y values in this are -1, so the point Q is (-1, -1)

hope this helps with the work
To solve for the total number of 12 – flag signals Sally
can make, we need to make use of the formula:
total flags = d! / (a! b! c!)
Where,
d = is the number of flags to create a signal = 12
a = number of red flags = 5
b = number of green flags = 3
c = number of white flags = 4
We can observe from the equation that the individual
number of flags is factored out (or divided from) that is because all the 5 red
flags are similar, all the 3 flags are similar and all 4 flags are similar.
Going back into the equation, by substituting and
calculating:
total flags = 12! / (5! 3! 4!)
total flags = 27,720
<span>Therefore there are about 27,720 different 12-flags
signals.</span>
Answer:
14 ft
Step-by-step explanation:
If 196 ft is the area of the sandbox, two equal sides must multiply to equal 196. 14×14=196
Answer:
163216
Step-by-step explanation:
If it's the sign of multiplication
404/4=101
2*2=4*101=404^2=163216
or,
If it's x
(404/4)x(2x2)
(101)x(2x2)
101x (4x)^2
1616x^2
2611456
I am not sure if it's right
