Answer:
After 4 years, the value of the car would be of $5695.31.
Step-by-step explanation:
The formula for compound interest works perfectly in this case:
As in this case the repetitions per annum are just 1 (yearly), we can ignore the n.
Replacing variables with our values, a yields the depreciated value:
Answer:
y = 1/7x + 22
Step-by-step explanation:
since the line is <u>parallel</u>, the <u>slope should be the same</u>.
so we need to find the y-intercept to put in into slope-intercept form.
what I do, is simply plug in the y and x points into the equation y=mx+b
y=mx+b <em>-formula used</em>
21 = 1/7(-7) + b <em>-plug in</em>
21 = -1 + b <em>-multiply 1/7 and -7</em>
22 = b <em>-simplify to get the y-intercept</em>
since we now know the y-intercept and the slope, we can plug them in to get our answer, which will be y = 1/7x + 22
7b+12=5b
Subtraction property of equality
7b + 12 - 12 = 5b - 12
Simplifying
7b = 5b - 12
Subtraction property of equality
7b - 5b = 5b - 12 - 5b
Simplifying
2b = -12
Division property of equality
2b/2 = -12/2
Simplifying
b = -6
