balandron [24]

I am slightly confused by your wording in the last sentence, but if you are trying to figure out how many children attended the concert you would use the second statement. The first statement does not tell you if the students are "children" are not so that is not an appropriate choice.

find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y= -3/4 x-3

Rzqust [24]

Answer:

$4x - 3y -3=0$

Step-by-step explanation:

Given equation ,

$\implies y =\dfrac{-3}{4}x - 3$

Compare it to slope intercept form to find the slope which is $y=mx+c$ , we have ,

$m =\dfrac{-3}{4}$

Now we know that the product of slope of two perpendicular lines is-1 . Hence the slope of the perpendicular line is ,

$m_{perp}= \dfrac{4}{3}$

The given point is (0,-1) , on using Point slope form of the line we have,

$\implies y-y_1 = m(x - x_1) \\\\\implies y -(-1) = \dfrac{4}{3}(x -0 ) \\\\\implies y + 1 =\dfrac{4}{3}x \\\\\implies \underline{\boxed{\red{ 4x - 3y -3 = 0 }}}$

Triangle ABC has vertices at A(1,2) B(4,6) and C(4,6) in the coordinate plane. The triangle will be reflected over the x-axis an

k0ka [10]

You should know that you can predict changes in coordinates after translations without a graph or anything like that.

(x, y) reflected over the x axis = (x, -y)
(x, y) reflected over the y axis = (-x, y)
(x, y) rotated 90 degrees around the origin = (y, -x)
(x, y) rotated 180 degrees around the origin = (-x, -y)
(x, y) rotated 270 degrees around the origin - (-x, y)

So here's our set of points.
A(1, 2), B(4, 6), C(4, 6)

Here's those points reflected over the x axis.
A'(1, -2), B'(4, -6), C'(4, -6)

And here's those points rotated 180° around the origin.
A''(2, -1), B''(6, -4), C''(6, -4)

I think you made a mistake writing down the question, though, because B and C are the same yet you say ABC forms a triangle. You should be able to go through this process with whatever the coordinate was supposed to be.
