The equation of line c is y=-4/3-4 Line d includes the point (4,-4) and is perpendicular to line c . what is the equation of line d?
Answers
Assuming that you mean that the equation of line c is
We can deduce that the slope of line c is
since the slope is the coefficient multiplying x in the equation of a line. Since we want line d to be perpendicular to line c, their slope must be in the following relationship:
So, line d has slope 3/4 and passes through point (4,-4). Use the equation
to find the equation of line d, where

8x - 4(0) = 24
8x - 0 = 24
8x = 24
8 8
x = 3
(x, y) = (3, 0)
Y - Intercept: 8x - 4y = 24
8(0) - 4y = 24
0 - 4y = 24
-4y = 24
-4 -4
y = -6
(x, y) = (0, -6)
Final answer:
The intercepts for the graph of the equation 8x-4y=24 are (0, -6) for the y-intercept and (3, 0) for the x-intercept.
Explanation:
To find the intercepts for the graph of the equation 8x-4y=24, we need to substitute 0 for x to find the y-intercept and substitute 0 for y to find the x-intercept.
For y-intercept:
8(0) - 4y = 24
-4y = 24
y = -6
So the y-intercept is (0, -6).
For x-intercept:
8x - 4(0) = 24
8x = 24
x = 3
So the x-intercept is (3, 0).
Thus, the graph has x & y intercepts as (3, 0) and (0, -6) respectively.

(a^2 + 4)(a^2 - 2)=0
we then get two answers from the brackets
a^2=-4
a= sqrt(-4) or 2j
and the second bracket gives us a^2=2
a= sqrt(2)
11. First expand the brackets.
Ax^3 + Bx^2 - x^2 + Bx +Cx + D
then equate the coefficients, this basically means put all the x^3, x^2 etc values together.
so Ax^3=3x^3 so we know that A=3Then put the x^2 together, so Bx^2-x^2=-x^2 and rearranging this gives B=0
Next we do Bx+Cx = 2x and we know that B is 0 so we can get rid of it and know that C = 2.
finally we can see that D = -7
