For the first one, divide by the coefficient of y which is three. y=5x-4
For the second one, add 21 on both sides and divide by three which gives y=4x+7

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: (f - g)(x)$

$\qquad \tt \rightarrow \: f(x) - g(x)$

Simple procedure :

$\qquad \tt \rightarrow \: 3x - 1 - (x + 2)$

$\qquad \tt \rightarrow \: 3x - 1 - x - 2$

$\qquad \tt \rightarrow \: 3x - x - 1 - 2$

$\qquad \tt \rightarrow \: 2x - 3$

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.

ollegr [7]

Answer:

k=5

Step-by-step explanation:

step 1

Find the equation of the line f(x)

we have the points

(-4,0) and (-2,2)

<em>Find the slope m</em>

$m=(2-0)/(-2+4)\\m=1$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(-4,0)$

substitute

$y-0=(1)(x+4)$

$y=x+4)$

Remember that

f(x)=y

$f(x)=x+4$

step 2

Find the equation of the line g(x)

we have the points

(-4,0) and (-2,-10)

<em>Find the slope m</em>

$m=(10-0)/(-2+4)\\m=5$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=5\\(-4,0)$

substitute

$y-0=(5)(x+4)$

$y=5(x+4)$

Remember that

g(x)=y

$g(x)=5(x+4)$

Remember that

$g(x)=kf(x)$ ------> $g(x)=5(x+4)$

therefore

k=5

I can't figure out 3/30 is in a percentage decimal or fraction please help me!!

Kamila [148]

If I am correct I do think the answer is 0.10 in decimal, in percentage it is 10% and fraction is 1 out of 30 I am not 100% sure so it would be better to double check
