4x-13
4(4)-13
16-13
3
The answer is 3.
This is two lines in slope intercept form and we want their intersection. We just set the ys equal.
-3x - 3 = (-1/2)x + 2
Multiply both sides by 2 to clear the fractions,
-6x - 6 = -x + 4
-10 = 5x
x = -10/5 = -2
y = -3x - 3 = -3 (-2) - 3 = 6 - 3 = 3
Check:
y = (-1/2)x + 2 = (-1/2)(-2) + 2 = 1 + 2 = 3, good
Answer: x=-2, y=3

Answer:
Cubic Function
Step-by-step explanation:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.
To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions
4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions
