Find the slope of each line.
What is the solution of the system of equations? y = –3x + 8 y = –5x – 2
Which graph represents the function of f(x) = the quantity of 4 x squared minus 4 x minus 8, all over 2 x graph of 2 x minus 4, with discontinuity at negative 1, negative 6 graph of 2 x minus 4, with discontinuity at 1, negative 2 graph of 2 x plus 2, with discontinuity at negative 1, 0 graph of 2 x plus 2, with discontinuity at 1, 4 please and thank you

Factoring by grouping is splitting middle terms into two appropriate terms.
let us see the resulting expression below as we factor the expression -8x3-2x2-12x-3.
-8x3-2x2-12x-3
= 2x^2 ( -4x-1) 3 (-4x-1)
=(2x^2+3) (-4x-1)
the resulting expression after factoring -8x3-2x2-12x-3 by grouping is:
(2x^2+3) (-4x-1)
The method factoring by grouping is widely used by college professors, teachers, students and even textbook authors.

because S(x,y) = (x, 1/2y), reverse what is done to y and simplify,
y = x^3 > y = 1/2*x^3 to compress vertically,
because S(x,y) = (x-7,y), reverse what is done to x,
y = 1/2*(x+7)^3 to shift to the left,
reflection across the x-axis changes positives to negatives,
y = -1/2(x+7)^3 to reflect across the x-axis.

Answer: x = -3
Step-by-step explanation: If a line has an undefined slope, it means that the line is vertical. A vertical line is parallel to the y-axis and does not have a slope.
To find the equation of a vertical line, we need to know the x-coordinate of any point on the line. In this case, the point (-3,4) is given.
Since the line is vertical and parallel to the y-axis, the equation of the line will be in the form x = constant, where the constant is the x-coordinate of the given point.
Therefore, the equation of the line that passes through the point (-3,4) and has an undefined slope is x = -3.

The verification of the given identity i.e. an (thetA) + cot (thetA) = 1 / sin (thetA) cos (thetA) so it should be explained below.
Verification of the identity:
Since
theta = t
tan t + cot t = 1/ sin t cos t
Now
sin t / cos t + cos t / sin t = 1 / sin t cos t
So,
( sin² t + cos² t ) / sin t cos t = 1/ sin t cos t
And, finally
1/ sin t cos t = 1 / sin t cos t

tan t + cot t = 1/ sin t cos t
sin t / cos t + cos t / sin t = 1 / sin t cos t
( sin² t + cos² t ) / sin t cos t = 1/ sin t cos t
1/ sin t cos t = 1 / sin t cos t
