Let f(x)=6/5x−1/2. Describe the transformations from the graph of f to the graphs of g(x)=−f(x) and h(x)=f(−x).

aivan3 [116]

Answer:

g(x)=-6/5x+1/2

h(x)=-6/5x-1/2

Step-by-step explanation:

1). g(x)=−f(x) ?

f(x)=6/5x−1/2

g(x)=−(6/5x−1/2)

2). h(x)=f(−x) ?

f(-x)=6/5(-x)−1/2

f(-x)=-6/5x-1/2

h(x)=-6/5x-1/2

A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?

vladimir1956 [14]

Answer: third option.

Step-by-step explanation:

By definition, a direct variation function has the form shown below:

$y=kx$

Where k is a constant.

Then, knowing the given points, you can calculate k with the formula for calculate the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-4-(-3)}{-12-(-9)}=\frac{1}{3}$

Substituting k into $y=kx$ , you obtain:

$y=\frac{1}{3}x\\\\y=\frac{x}{3}$

What is the sum of the first 30 terms in a(n)=4n+1

dimulka [17.4K]

Hello,

$\sum _{i=1} ^{30}(a_i)=\sum _{i=1} ^{30}(4*i+1)\\

=4*\sum _{i=1} ^{30}(i) +\sum _{i=1} ^{30}(1)\\

=4* \dfrac{31*30}{2} + 30 =1860+30=1890$
