Answer:

y=-1/7+48/7

Step-by-step explanation:

You want to isolate the Y so you subtract the x to the other side.

Next you divide both numbers on the right hand side by 7 and that gives you

y=-1/7+48/7

First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finall

Answer:

$(\frac{1}{3}x - 3,-\frac{1}{3}y+2)$

Both triangles will be similar

Step-by-step explanation:

See comment for complete question.

Given

Let the coordinates of the triangle be T(x,y)

First transformation: Dilation by 1/3

The new points will be:

$T' = \frac{1}{3}(x,y)$

$T' = (\frac{1}{3}x,\frac{1}{3}y)$

Second: Reflection over the x-axis

When a point (x,y) is reflected over the x-axis, the new point is (x,-y).

So, we have:

$T'' = (\frac{1}{3}x,-\frac{1}{3}y)$

Third: Translation 3 units left and 2 units up.

When a point (x,y) is translated b units left and h units up, the new point is (x - b,y+h).

In this case:

$b = 3$ and $h = 2$

So, we have:

$T''' = (\frac{1}{3}x - 3,-\frac{1}{3}y+2)$

Hence, the coordinate of the new triangle will be: $(\frac{1}{3}x - 3,-\frac{1}{3}y+2)$

<em>Additionally, both triangles will be similar because all the transformation done are rigid transformations i.e. Dilation, Reflection and Translation</em>

Suppose a triangle with angles measuring 37°, 59°, and 84° is reflected across the y-axis of a coordinate grid. Which would be t

stich3 [128]

I'm assuming there are supposed to be choices, but if a figure goes through only a reflection, then the angle measures will not change.

Need the answer ASAP

harina [27]

Answer:

The third one.

Step-by-step explanation:

The GCF between 10, 8, and 6 is 2, but they all have x, so the GCF for the variables is x. Divide the original value of the trinomial by the GCF and it will be factored.

Hope this helps!

State the point on the line y - 18 = 71.3(x +98)

krek1111 [17]

9514 1404 393

Answer:

(-98, 18)

Step-by-step explanation:

We recognize the equation as being in the "point-slope" form.

y -k = m(x -h) . . . . . . . a line with slope m through point (h, k)

Comparing this form to the given equation, we identify the parameters as ...

k = 18, m = 71.3, h = -98

The point on this line is (h, k) = (-98, 18).

3/4 of a sphere with a radius of 13

Brums [2.3K]

First fnd SA then times 3/4

SA of sphere=4pir^2
r=13
SA=4pi13^2
SA=4pi169
SA=676pi

times 3/4
SA=507pi

answer is 507pi squaer units

(if they want to evaluate or aprox, use 3.14 for pi and multiply 507 and 3.14)
