Answer:
For parallel line
y = -4x + 20
For perpendicular line
4y = x + 12
Step-by-step explanation:
Equations parallel to y + 4x = 10
y = 10 - 4x
Compared to y= mx + c
The slope here is -4.
A line parallel to this particular line will have same slope.
Thus, the slope of the line parallel to that line is also -4.
Now going to the equation of line using the points, we use the following formula
y-y1/x -x1 = m
This means y-4/x-4 = -4
y -4 = -4x + 16
y = -4x + 20
For a line perpendicular to that line, the product of their slope equals -1. Since the slope of the first is -4, then the slope of the perpendicular line would be -1/-4 = 1/4
The equation of the line is thus as used before,
y -y1/x-x1 = m
y - 4/x -4 = 1/4
4y -16 = x -4
4y = x + 12
Try this option:
the rule: if f(-x)=f(x), then the function f(x) is even, if f(-x)=-f(x) then the function is odd.
1. f(x)=-5x⁴-2;
if to substitute x→(-x), then f(-x)=-5*(-x)⁴-2; ⇔ f(-x)=-5x⁴-2, in other words f(x)=f(-x), it means that this function is even.
2. f(x)=x³+2x.
if to substitute x→(-x), then f(-x)=(-x)³+2*(-x); ⇔ f(-x)=-(x³+2x), in other words f(-x)=-f(x), it means that this function is odd.
Answer:
I think its B the line is so going decreasing
Step-by-step explanation:
Answer:
This has no particular answer since I don't know.
Step-by-step explanation:
So, to get this time, you need to round up 11:39 to 11:40, then you need to count by 5's until you get to 3:15, then you need to subtract one.
Add 7 to both sides
At the left hand side 7 will cancel 7
At the right hand side 7 will add up
Divide through by 2
simplify the fraction
