Give the equation of the line passing through the point (20,2)that is perpendicular to y=−4x.
Cerrena [4.2K]

Answer:

y-2 = 1/4(x-20)  point slope form

y = 1/4x -3  slope intercept form

Step-by-step explanation:

y = -4x

The slope is -4

The slope that is perpendicular is the negative reciprocal

- (1/-4) = 1/4

The slope of our new line is 1/4

We have a point and the slope, so we can use point slope form

y-y1 = m(x-x1)

y-2 = 1/4(x-20)

If we want the line in slope intercept form, distribute

y-2 = 1/4x -5

Add 2 to each side

y-2+2 = 1/4x -5+2

y = 1/4x -3

HELP! (Urgent pre-calculus question.)
marishachu [46]
2. means that for every x, there is eactly one y
basically, we can use the vertical line test to see if it crosses at any 2 points

first one works
2nd one works
3rd works
4th works
5th works
they are all one to one functions



3.
easy
steps
for f(x)=?
replace f(x) with y
switch x and y
solve for y
replace y with  f⁻¹(x)
so

f(x)=(1+x)^3-2
replace
y=(1+x)^3-2
switch
x=(1+y)^3-2
solve
x+2=(1+y)^3
\sqrt[3]{x+2}=1+y
-1+\sqrt[3]{x+2}=
replace
f^{-1}(x)=-1+\sqrt[3]{x+2}
first option



4.
domain, hmm we can't divide by 0 so domain is all real numbers except for x=0
domain is (-\infty,0) \cup(0,\infty)
hmm, range
as x approaches negative or positive infinity, f(x)=5
as x approaches 0 from the left, f(x) appraoches negative infintiy
as x approaches 0 from the right , f(x) appraoches positive infintiy
so range is (-\infty,5) \cup(5,\infty)

domain is (-\infty,0) \cup(0,\infty)
range is (-\infty,5) \cup(5,\infty)
answer is the 4th option
