Answer:
-47/8.
Step-by-step explanation:
If the line has a slope of -1/8, that means the equation y = mx + b will be y = -1/8x + b.
In this case, we are given a point: (9, -7). That means that x = 9 and y = -7.
-7 = (-1/8)(9) + b
b - 9/8 = -7
b = -56/8 + 9/8
b = -47/8 = -5.875 = -5 and 7/8, which is your y-intercept!
Hope this helps!
Given that:
we get that:
Now, recall that the interior angles of a triangle add up to 180°, therefore:
Substituting:
in the previous equation, we get:
<h2>Answer: </h2>
Answer:
A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year.
Write an exponential function that models the value of the car, y, over x years.
To the nearest cent, what will be the value of the car after eight years?
Step-by-step explanation:
Answer:
Its probably 6.4 I dont know if I'm correct because I forget stuff
<span>The first number = x
The </span>second number = 2x-3
x + 2x-3 = 36
3x = 36+3
3x = 39
x = 39/3
x = 13
The first number = x = 13
The second number = 2x-3 = 2*13 - 3 = 26 - 3 = 23
