Mathematics
1 answer:
horsena [70]3 years ago
7 0

Answer:

Option (2)

Step-by-step explanation:

ΔDEF is a dilation image of ΔABC.

Rule for the dilation,

Scale factor = \frac{\text{Length of one side of the image triangle}}{\text{Length of one side of the original triangle}}

                    = \frac{DE}{AB}

                    = \frac{4}{8}

                    = \frac{1}{2}

Therefore, scale factor by which ΔABC is dilated is \frac{1}{2}.

Option (2) will be the correct option.

4x – (6 – x) = 12 + 4x
devlian [24]

4x - (6-x) = 12 + 4x

4x - 6 + x = 12 + 4x

      5x - 6 = 12 + 4x

    5x - 4x = 12 + 6

             x = 12 + 6

             x = 18

Need asap help ,struggling !
zepelin [54]

Answer:

A.) x = 1000 kilowatt-hours

Step-by-step explanation:

Because Micah was charged 113.94 total for the month, this is the y value. We are trying to find x, how much electricity he used. We would start by making the equation: 113.94 = 0.11x + 3.94

Now, we need to get x alone.

(Subtract 3.94 from both sides) 110 = 0.11x

(Divide by 0.11) x = 1000 kilowatt-hours

Hope this helps!
