Answer:
The answer to question 3 is : 2x^2 + 5x + 3
Step-by-step explanation:
The FOIL method is multiplying the first variables, the outside variables, the inside variables and the last variables.
(2x + 3)(x + 1)
F = 2x times x = 2x^2
O = 2x times 1 = 2x
I = 3 times x = 3x
L = 3 times 1 = 3
2x^2 + 5x + 3
I'll leave the rest to you. You got this!
Answer:
Perpendicular: 4, Parallel: -1/4
Step-by-step explanation:
The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.
First write the equation of the line in slope-intercept form
-x-4y=7
-4y=x+7
y=-(1/4)x-7/4;
The slope to the line is -1/4; Now find the slope of the perpendicular line;
-(-1/4)^-1 = 4
4
The slope of a line parallel to a line is the same as the given slope;
when we calculated the given slope, it was -1/4
The slope of the line parallel to this line is also -1/4
-1/4
