Mathematics
1 answer:
Andrej [43]3 years ago
3 0

Answer:

Step-by-step explanation:

It appears to be the last step there that has evaded you.  In the second line of work, you can see that what's in each set of parenthesis is exactly the same.  Because of this, it is common and can be factored out.  What's left is the 4x and the +5:

(5x - 3)(4x + 5)

That's factoring by grouping.  It only works with polynomials that have an even number of terms so you can group them together in 2's.

The pair of points lies on the same line with the given slope. Find x.
KIM [24]
If the gradient is -2 that just means we work back the way, the method i use to find the gradient is y^2-y^1/x^2-x^1 so if we sub the variables in that gives us -18-(-8)/3-x so if we add that up we get -10/3-x, so what has to be on the bottom to get -2? in this case it would be -2 so the overall answer would be -10/5 which would give us a slope of -2 when simplified :) hope this helps

A car is purchased for $27,500. After each year, the resale value decreases by 35%. What will the resale value be after 5 years?
e-lub [12.9K]

Answer:

$3,190.80

Step-by-step explanation:

yr 1:

27500 x .35 = 9625

27500 - 9625 = 17875

yr 2:

17875 x .35 = 6256.25

17875 - 6256.25 = 11618.75

yr 3:

11618.75 x .35 = 4066.5625

11618.75 - 4066.5625 = 7552.1875

yr 4:

7552.1875 x .35 = 2643.265625

7552.1875 - 2643.265625 = 4908.921875

yr 5:

4908.921875 x .35 = 1718.12265625

4908.921875 - 1718.12265625 = 3190.79921875
