Slope =(y2-y1)/(x2-x1)
=(-4-5)/(-2-3)
=-9/-5
=9/5

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)

Find the slope m

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

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)

Find the slope m

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

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

Answer:All real numbers except for 0 and 4.

Step-by-step explanation:

The denominator cant be zero so we take it and equal it to zero. For the denominator to equal to zero, either x = 0 or x=4 yields 0.

An oil change at City Auto is regularly $30. Mr. Allen has a coupon for 15% off. He wants to know the sale price of the service.

What is the relationship between the sale price and the regular price of an oil change? Complete the statement.

The sale price is (1,2 or 3)% of the regular price.

1. 15%

2. 30%

a chemistry lab, you have 2 vinegars. One is 5% acetic acid, and the other one is 6% acetic acid. You want to make 200 ml of vin

BigorU [14]

0.5*x+0.6*y=0.6(200) where x is quantity of 1st and y is 2nd vinegar.

so, 5x+6y=6(200)=1200
5x+6y=1200......(1)
x+y=200..........(2)

(1)-5*(2)⇒y=1200-1000=200,x=0

so, you just take 200 ml of second vinegar. In fact, this calculation can be skipped coz we were asked the 2nd vinegar directly in the question.
