PLEASE HELP ME FAST (It's about y-intercept) This is the Last one I have to answer then I am at a 100 I've been working on this are day so please don't give me a wrong answer.

To find a y-intercept, you set x=0 and solve for y.

    y = 16(0) + 41

    y = 41

PS

If the equation is in slope-intercept form like this, the y-intercept is always the number at the end, the "b" from y=mx+b.

41

Step-by-step explanation:

It is y=mx+b where b is the slope-intercept for the y-axis, so the answer is 41 as our equation is y = 16x + 41

If it is not in y=mx+b set the x to 0 and solve :D

Good luck :))

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.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
