OleMash [197]
The ordered pairs would be (x-2, -y).

Translating a graph to the right subtracts the number of units from the x-coordinate.

Reflecting across the x-axis negates the y-coordinate.

Answer:

its none of these answers ;-;

Step-by-step explanation:

3^2 + 8 ÷ 2 - (4 + 3)

we do what's in parentheses first. (pemdas)

so now we have, 3^2 + 8 ÷ 2 - 7

next exponents, 3^2=9

9 + 8 ÷ 2 - 7

next division, 8÷2=4

9 + 4 - 7

next addition, 9+4=13

13-7

finally subtraction, 13-7=6

final answer: 6

ERROR ANALYSIS In Exercises 39 and 40, describe and
expeople1 [14]

Answer:

39. r = 13.4

40. m = 12

Step-by-step explanation:

39. Given the equation, -0.8 + r = 12.6, to solve for r, the following are the correct steps to take to arrive at the solution:

-0.8 + r = 12.6 (given)

Add 0.8 to both sides of the equation (addition property of equality)

-0.8 + r + 0.8 = 12.6 + 0.8 (this is where the error occurred.)

r = 13.4

40. The correct steps to take in solving the equation, -\frac{m}{3} = -4 is as follows:

-\frac{m}{3} = -4 (given)

Multiply both sides by 3 (multiplication property of equality)

3*-\frac{m}{3} = 3*(-4)

-m = -12 (this is where the error occurred. This is what we should have at this line/step)

m = 12 (dividing both sides by -1)
