When solving a system by multiplying and then adding or subtracting, how do you decide whether to add or subtract?

1 answer:

8 0

i don’t know if your school does PEMDAS but it stands for parentheses, exponents, multiplication, division, addition, and then subtraction. so you would multiply, then add, and then subtract.

Image point N'(12, -6) was dilated from the pre-image point N(4, -2). What was the scale factor used?

skelet666 [1.2K]

The scale factor's 3 since 12 and 4 can be divided by 3 and -6 and -2 can also be divided by 3.

Find the coordinates of P ' if D o, 2.4 (x,y) is applied to the triangle below

guajiro [1.7K]

Answer:

The coordinates of P' are (4.8,-4.8).

Step-by-step explanation:

The rule of dilation $D_{o,2.4}(x,y)$ represent the dilation with scale factor 2.4 and center at origin.

If the scale factor of the dilation is k and the center is (0,0), then

$(x,y)\rightarrow (kx,ky)$

Since the scale factor is 2.4, therefore

$(x,y)\rightarrow (2.4x,2.4y)$

From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are

$P(2,-2)\rightarrow P'(2.4(2),2.4(-2))$

$P(2,-2)\rightarrow P'(4.8,-4.8)$

Therefore the coordinates of P' are (4.8,-4.8).
