8x + 3 = -39
8x + 3 -3 = -39 - 3
8x = -42
8x/8 = -42/8
x = -5.25
Answer:
Step-by-step explanation:
It is given that he vector y = ai + bj is perpendicular to the line ax + by = c.
Given given point is P(-1,-9) and given vector is v = -4i + j.
Here, a = -4 and b= 1.
We need to find the equation of the line through P perpendicular to v.
Using the above fact, the vector v = -4i + j is perpendicular to the line
... (1)
The line passes through the point (-1,-9).
Substitute x=-1 and y=-9 in the above equation to find the value of c.
The value of c is -5.
Substitute c=-5 in equation (1).
Therefore the equation of line which passes through P and perpendicular to v is -4x+y=-5.
Answer:
32w^3 + 16x^2 - 8
Step-by-step explanation:
Perimeter = 2L + 2W
L = 9W^3 + 8W^2, W = 7w^3-4
2(9w^3 + 8w^2) + 2(7w^3 - 4)
= 18w^3 + 16w^2 + 14w^3 - 8
Combine like terms
32w^3 + 16w^2 - 8
