30. is just asking where the two equations graphed intersect each other...
x = -3 and x = 1 for intersections.
Answer:
Slope of 3/4 (3,4) between points
Step-by-step explanation:
Answer:
the y-intercept is -18
Step-by-step explanation:
hope i couldve help :)
(x+y-3)(x+y+3) = x^2+xy+3x+xy+y^2+3y-3x-3y-9 = -9+x^2+y^2+2xy
For this case, the first thing to do is to use the equation of the given line.
We have then:
f (x) = 0.76x + 42.39
We substitute the value of x = 15:
f (15) = 0.76 * (15) + 42.39
f (15) = 53.79
Then, subtracting with the original value we have:
53.79-52.04 = 1.75
Answer:
the residual for when x = 15 is:
1.75
