Answers

Answer:

The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Example: Here, XYUV=123=4 . So, the scale factor is 4

Step-by-step explanation:

Answer:

the scale factor would be 4

Step-by-step explanation:

also  

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor for volume of one half. The basic equation for it is image over preimage.

Step-by-step explanation:

x+3y=-2 and 5x-3y=26 in (x,y) form pls!!

Answers

x + 3y = -2

=> x = -2-3y ----i

Also 5x -3y = 26

=> 5 (-2-3y) -3y =26

=> -10 -15y -3y =26

=> -18y = 36

=> y = -2

Putting y = -2 in equation i we get,

x= -2 -3(-2)

=> x = -2 +6

=> x = 4

Thus The solution is (4, -2)

Answer:

(4, -2)

Step-by-step explanation:

Please be sure to share ALL of the instructions.  Here you meant "Solve the following set of simultaneous equations and present your solution in (x, y) form."

Note that the first equation features +3y and that the second features 5x - 3y = 26.  Simply adding like terms results in our having eliminated the variable y:

6x = 24

Then x = 24/6 = 4

The x coordinate of the solution is 4;  Substituting 4 for y in the first equation results in

4 + 3y = -2

which simplifies to 3y = -6.  Thus, y = -2, and the solution is

(4, -2)
