Given the equation, y = 5x – 2, the y-intercept is -2. Why isn’t the y-intercept a positive 2? Explain. (20 points)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: 12   they all have at least 28 days

step-by-step explanation: haha

60: 45 =12: 9 =4: 3 so the answer is 4: 3
