Which linear function represents the line given by the point-slope equation y-8= 1/2(x-4)

vitfil [10]

Y - 8 = (1/2)(x - 4)

y - 8 = 0.5*x - 0.5*4

y - 8 = 0.5x - 2

y = 0.5x - 2 + 8

y = 0.5x + 6 is the linear function.

Estimates show that there are 1.4x10^8 pet fish and 9.4x10^6 pet reptiles in the United States. How many pet fish and reptile pe

azamat

Answer:

There are total number of pet fish and reptile pets are $1.49\times 10^8$ .

Step-by-step explanation:

Number of pet fish are $1.4\times 10^8$ and the number of pet reptiles are $9.4\times 10^6$ .

It is required to find the total number of pet fish and reptile pets in the United States. It can be done by simply adding the above numbers such that total numbers are given by :

$T=1.4\times10^{8}+9.4\times10^{6}\\\\T=149400000\\\\T=1.49\times 10^8$

So, there are total number of pet fish and reptile pets are $1.49\times 10^8$ .

Last year a construction worker had a gross income $ 29,700, of the which he contributed 7% to his 401(k) plain. If he got paid

AlladinOne [14]

Divide the gross income by 12 to find his monthly pay:

29,700 / 12 =$2,475 per month.

Multiply his monthly pay by 7%:

2,475 x 0.07 = $173.25 into his 401(k) per month.

The answer is A.

Write the equation of the line in slope-intercept form that has the following points: (2, -1)(5, -3)

kirza4 [7]

Answer:

$\large\boxed{y=-\dfrac{2}{3}x+\dfrac{1}{3}}$

Step-by-step explanation:

The skope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, -1) and (5, -3). Substitute:

$m=\dfrac{-3-(-1)}{5-2}=\dfrac{-3+1}{3}=\dfrac{-2}{3}=-\dfrac{2}{3}$

We have the equation:

$y=-\dfrac{2}{3}x+b$

Put the coordinates of the point (2 , -1) to the equation:

$-1=-\dfrac{2}{3}(2)+b$

$-1=-\dfrac{4}{3}+b$ <em>add 4/3 to both sides</em>

$\dfrac{1}{3}=b\to b=\dfrac{1}{3}$

Finally we have:

$y=-\dfrac{2}{3}x+\dfrac{1}{3}$
