Ymorist [56]

Answer:

The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Find the equation of the line with slope = 6 and passing through (-9,-58). Write your equation in the form y = mx+ b
stira [4]

Answer:

<u>y=6x-4</u>

Step-by-step explanation:

<u>What we know</u>

  • the slope is 6
  • our point is (-9,-58)

-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this

-58=6(-9)+b

-58=-54+b

-58=54+b        - we changed -54 to a positive 54

54-58=-4

y=6x-4

The value of a car depreciates by 40% each year. At the end of 2007 the value of the car was £3600 Work out the value of the car
natima [27]

Answer: $6,000

Step-by-step explanation: If set up correctly, the value of the car at the end of 2006 times 0.6 (because the car is losing 0.4 of its value, so it keeps 0.6 of its value) should get you the value of the car at the end of 2007.

The equation should look like this:

(value of the car at the end of 2006) x 0.6 = (value of the car at the end of 2007)

Then you substitute: (value at the end of 2006) x 0.6 = 3600

Then divide: (value at the end of 2006) = 0.6 ÷ 3600

Then substitute again: (value at the end of 2006) = 6,000

Hope this helped you! Feel free to ask me any questions!
