First, a little housekeeping!!

1+1+7x​2​​+7y​3​​+3+2x​2​​−y​3​​ needs to be written as <span>1+1+7x​^2​​+7y​^3​​+3+2x​^2​​−y​^3.  The " ^ " signifies exponentiation and is essential here.

Now combine like terms:

7y^3-y^3   +   7x^2 + 2x^2 + 1 + 1 + 3

You'll get     6y^3 +9x^2 +  5.​​</span>

Triangle FGH has the following side lengths: FG = 5 ft, GH = 10 ft, HF = 12 ft Triangle PQR is similar to triangle FGH. The long
7nadin3 [17]
The first thing we must do for this case is find the scale factor.
 We have then that for the larger side of both triangle, the scale factor is:
 k =  \frac{RP}{HF}
 k = \frac{7.2}{12}
 k = 0.6
 To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
 We have then:

 For PQ
 
PQ = k * FG&#10;&#10;PQ = 0.6 * 5&#10;&#10;PQ = 3

 For QR
 
QR = k * GH&#10;&#10;QR = 0.6 * 10&#10;&#10;QR = 6

 Answer:
 
You have that the lengths for the other two sides of triangle PQR are:
 
PQ = 3&#10;&#10;QR = 6

Point M (-3, 5) is translated using this rule. (x, y) ----&gt; (x - 1, y) What are the coordinates of M'?
Nuetrik [128]

Answer:

The coordinates of point M' are M'(x,y) = (-4, 5).

Step-by-step explanation:

According to the statement, we have the following translation rule:

M'(x,y) = M(x,y) + (-1, 0) (1)

Where:

M(x,y) - Original point.

M'(x,y) - Translated point.

(-1, 0) - Translation vector.

If we know that M(x,y) = (-3, 5), then the coordinates of the point M' are:

M'(x,y) = (-3,5) + (-1,0)

M'(x,y) = (-4, 5)

The coordinates of point M' are M'(x,y) = (-4, 5).
