What are the coordinates of D’

Mathematics
1 answer:
agasfer [191]3 years ago
3 0

Answer:

(-2,-1)

Step-by-step explanation:

Reflection across the x-axis is: (x,y)\rightarrow(x,-y)

We need to multiply the y-value of the pre-image by negative one to get reflected across the x-axis.

1 * -1 = -1

So:

(-2,1)\rightarrow(-2,-1)

D' should be (-2,-1).

Is the ordered pair (-2, 1) a solution to the equation - 3x + y = 5? <br>No <br>Yes​
Otrada [13]

Answer:

No

Step-by-step explanation:

Plug (-2,1) into -3x+y=5. This will make it -3(-2)+(1)=5. This is equal to 6+1=5. 7=5. 7 is not equal to 5. Therefore, (-2,1) is not a solution to the equation -3x+y=5.

PLEASE HELP ME 3X+1/14=2X/8 WHAT IS  X? EXPLAIN HOW YOU GOT THE ANSWER
balandron [24]
Cross-multiply so that 8(3x + 1) = 14(2x)

Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x

Subtract 24x from both sides:
8 = 4x

Divide both sides by 4:
x = 2
