B is the midpoint of ACand E is the midpoint of BD. If A(-9, -4), C(-1, 6), and E(-4, -3), find

the coordinates of D.

Answers

Answer 1

Answer:

[tex]Solution,\\Midpoint of coordinates (a ,b) and (c,d) is given by:\\(x,y) = (\frac{a+b}{2} , \frac{c+d}{2}) \\Therefore, coordinate of B is\\(\frac{-9-1}{2},\frac{-4+6}{2}) = (\frac{-8}{2},\frac{2}{2}) = (-4 , 1)[/tex]

[tex]Similarly,\\E(4, -3) = (\frac{-4+x}{2},\frac{1+y}{2}) where, (x,y) are the coordinates of D\\or, 4=\frac{x-4}{2} and -3 = \frac{y+1}{2}\\or, 8 = x - 4 and -6 = y+1\\or, x= 12 and y = -5\\Therefore, the coordinates of D are (12,-5)[/tex]

slope is 2 and contains the point (5,-7)

write the equation of a line ​

Answers

Answer:

y = 2x - 17

Step-by-step explanation:

y = mx + b

m = 2

y = 2x + b

Plug in (5, -7) for x & y.

-7 = 2(5) + b

-7 = 10 + b

Subtract 10 from both sides.

-17 = b

y = 2x - 17

Check work.

-7 = 2(5) - 17

-7 = 10 - 17

- 7 = -7

2 1/5 - 5/6 =

Answers

Answer:

2 1/5 - 5/6 = 41/30

Step-by-step explanation:

Turn the denominator to be the same because if the denominator is not the same so you can't subtract neither can you add.

Next find the least common multiple of both denominator (5, and 6) and ask yourself what time the denominator would give you the least common multiply you got.

1/5 x 6/6 = 6/30 and 5/6 x 5/5 = 25/30

Your expression now would be 2 6/30 - 25/30

You can't subtract 6 from 25 so you have to turn the proper fraction into a improper fraction

2 6/30 = 2 x 30 + 6 = 66/30. 25/30 = 0 x 0 + 25 = 25/30.

Your new expression would be:

66/30 -  25/30

Now you can subtract 66 - 25 and you get 41

Therefore the correct answer is 41/30 you can not simplify the answer because the numerator is a odd number and the denominator is a even number.

Given f(x) = x^3 + kx + 2, and x + 1 is a factor of f(x), then what is the value of
k?

Answers

Answer:

k = 1

Step-by-step explanation:

Given that,

[tex]f(x) = x^3 +kx + 2[/tex]

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

[tex]x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1[/tex]

So, the value of k is 1.

If 176 dollars = 100 pounds and 1 pound = NRs. 119,
how much Nepali rupees can be exchanged with 132 dollar? find it​

Answers

Answer:

NRs. 8925

Step-by-step explanation:

176 dollars = 100 pounds

132 dollars = ??? pounds

Using cross-multiplication, we get:

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Now, 1 pound = NRs. 119

So 75 pounds = NRs. ???

Using cross-multiplication again, we get:

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925  

So the answer is 8925 Nepali rupees

The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925

Calculation of the amount:

Since

176 dollars = 100 pounds

And, for 132 dollars = ??? pounds

So here we applied cross multiplication

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Also, 1 pound = NRs. 119

Now

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925

what is the equation of the line passing through the point (2,-1) with a slope of -3

Answers

Note: this answer assumes that the equation of the line must be in slope-intercept form.

Answer:

[tex]y= -3x + 5[/tex]

Explanation:

When you need to write an equation and know its slope and a point it intersects, you can use the point slope formula [tex]y-y_1 = m (x-x_1)[/tex] first. In order to write an equation using this formula, the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted in for real values.

The [tex]m[/tex] represents the slope, so write the slope of this equation, -3, in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. We know that the line must intersect the point (2, -1). Write 2 in the place of

[tex]y-(-1) = -3(x-(2))[/tex]

[tex]y+1 = -3(x-2)[/tex]

Now, to put it in slope-intercept or [tex]y = mx + b[/tex] form, just expand the right side and isolate [tex]y[/tex]:

[tex]y+1 = -3(x-2)\\y + 1 = -3x + 6 \\y = -3x + 5[/tex]

Therefore, [tex]y= -3x + 5[/tex] is the answer.

Given ΔPQR and ΔSTU, what is m∠Q?

Answers

Given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.

Similar TrianglesThe ratios of the corresponding sides of similar triangles are always equal to each other, that is, the corresponding sides are proportional.Also, corresponding angles of two similar triangles are congruent.

Thus:

ΔPQR and ΔSTU are similar because:

PQ/ST = PR/SU = QR/TU = 3.5

Therefore,

m∠Q = 180 - 70 - 46

m∠Q = 64°

Thus, given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.
