Answer:

y=5/2 . *the question doesn't specify a y-intercept for the perpendicular line so just leave it as if it passes through 0.

Step-by-step explanation:

First, you isolate y to put the line in slope intercept form. Then, you take the slope and find the reciprocal(-5/2) then flip the sign giving you a slope of 5/2.

Eddi Din [679]

Combine like terms: 11 + 3x^3 + 4x^2 + -2 + 3x
(3x^3) + (4x^2) + (3x) + (11 + -2)

= 3x^3 + 4x^2 + 3x + 9. which is the answer :)

What is the solution of this equation? -1/2n2+18=0

SashulF [63]

Answer:

$n=-6\text{ or } n=6$

Step-by-step explanation:

So we have the equation:

$-\frac{1}{2}n^2+18=0$

Subtract 18 from both sides. The left cancels:

$-\frac{1}{2}n^2=-18$

Multiply both sides by -2. The left cancels again:

$n^2=36$

Take the square root of both sides:

$n=\pm\sqrt{36}$

Since we're taking the square root, we need to use plus-minus.

Evaluate:

$n=\pm 6$

So, the solutions are -6 or 6.
