Is f(x)=6x a direct variation
Answer:
[tex]f(x)=6x[/tex] is a direct variation.
Step-by-step explanation:
Given the function
[tex]f(x)=6x[/tex]
We have to determine whether the equation [tex]y=6x[/tex] is a direct variation or not.
As we know that in direction variation, y and x increase or decrease by the same factor by the formula
[tex]y=kx[/tex]
where 'k' is the constant of variation
Given the function
[tex]y=6x[/tex]
Here 6 is the constant of variation ∵ [tex]y=kx[/tex]
Also y and x increase and decrease by the same factor
For example,
when x=6, y = 6(x)=6(6)=36
when x=8, y = 6(x) = 6(8) = 48
Hence, when x increase, the y increases by the same factor.
Therefore, [tex]f(x)=6x[/tex] is a direct variation.
Make r the subject of the formula t=r/r-3
Answer:
[tex]r = \frac{3t}{t-1}[/tex]
Step-by-step explanation:
[tex]t = \frac{r}{r - 3}[/tex]
Cross multiply,
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t -1) = 3t
[tex]r = \frac{3t}{t-1}[/tex]
Answer:
r = 3t/(t - 1)
Step-by-step explanation:
t = r/(r - 3)
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t - 1) = 3t
r = 3t/(t - 1)

Find the rate of change of the linear function
shown in the graph. Then find the initial value.
Answer:
4 ; Initial value is (- 1)
Step-by-step explanation:
The rate of change of a linear function is slope of the line.
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(0, - 1)
(1, 3)
m = [tex]\frac{-1-3}{0-1}[/tex] = 4
Initial value is - 1
y = 4x - 1
The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given graph,
The rate of change or slope of a function is the ratio of the difference of y's and x's coordinates.
Therefore, let's consider two points (0,-1) and (1,3)
Slope = (3 - (-1))/(1 - 0)
Slope = 4
The y-intercept is -1 so the equation will be y = 4x - 1.
The initial value of function at x = 0 is y = 4(0) - 1 = -1.
Hence "The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1".

Answer:
C = 94
Step-by-step explanation:
Say the centre point is Y, then the triangle BCY is an isosceles, therefore angle BCY = angle CBY
So the base points of that triangle are both 47, to find the angle of BYC, you just do:
180 - 47 - 47 = 86
and then since x is on a line with 86, and angles on a straight line add up to 180:
180 - 86 = 94
answer is 94 degrees
