Answer:

(-4,-8)

Step-by-step explanation:

Given is a picture with a point R and a line PQ

We have to find the point out of the 4 options lying on the perpendicular line to PQ through R

R is the point (4,2)

P is (-6,4) and Q is (4,-4)

Slope of PQ = \frac{-4-4}{4+6} =-0.8

Slope of perpendicular line would be = \frac{1}{-0.8} =-1.25

Equation of the line through R with slope -1.25 is

y-2=1.25(x-4)\\y =1.25x-3

Out of the four options,

only (-4,-8) satisfies

because -8 =-1.25(-4)-3

so answer is (-4,-8)

Can someone help me please.

Answer:

  1. Lena's Method: 280
  2. Jackson's Method: 280

Step-by-step explanation:

Lena's Method:

  1. 8 + 12 = 20
  2. Plug 20 in: 14(20)
  3. 14(20) = 14 × 20 = 280

Jackson's Method:

  1. 14 × 8 = 112
  2. 14 × 12 = 168
  3. Re-write the expression: 112 + 168
  4. 112 + 168 = 280

I hope this helps!
