Answer:

The numerical expression is simplified into 8.

Step-by-step explanation:

You have to use the P.E.M.D.A.S. formula.

16-8[(3+6)÷9]

Solve the brackets(parenthesis) first.

Inside the brackets, you have to use the P.E.M.D.A.S. formula once again, as if it was a different equation.

16-8[(9)÷9]

Once you've found the solution to the equation 3+6 inside the parenthesis, you divide it by 9.

16-8[1]

Then, since there are no exponents, you multiply.

16-8

Then you subtract.

What are the coordinates of R' for the dilation D(0.5. p)(PQRS)?

11111nata11111 [884]

Answer:

$R' = (-1,-0.5)$

Step-by-step explanation:

See attachment for complete question.

From the attachment:

$P = (-3,-3)$

$R = (1,2)$

Dilation:

$D_{(0.5,P)}$

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

$R = (1-(-3),2-(-3))$

$R = (1+3,2+3)$

$R = (4,5)$

Next, apply dilation factor 0.5

$R' = R * 0.5$

$R' = (4,5) * 0.5$

$R' = (4* 0.5,5* 0.5)$

$R' = (2,2.5)$

Lastly, measure R' from the origin by adding the coordinates of P to R'

$R' = (2+(-3),2.5+(-3))$

$R' = (2-3,2.5-3)$

$R' = (-1,-0.5)$
