Find the equation of the linear function represented by the table below in slope-

pav-90 [236]

Answer: $y=-3x-2$

Step-by-step explanation:

Using the values $x=-2, y=4$ and $x=1, y=-5$ , the slope is $\frac{-5-4}{1-(-2)}=-3$ .

So, the equation is:

$y-4=-3(x+2)\\\\y-4=-3x-6\\\\y=-3x-2$

Find the length of a segment with an endpoint of (2, 1) and a midpoint of (–2, –1).

Travka [436]

Answer:

Length of segment $=4\sqrt5$ units = 8.94 units

Step-by-step explanation:

Given:

End point of line: (2,1)

Midpoint of line: (-2,-1)

To find length of line segment.

Solution:

Distance from endpoint to midpoint is half the length of segment as the midpoint divides the line into equal halves.

Distance from end point to mid point can be found out using distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2)$

Plugging in points for end point (2,1) and midpoint(-2,-1).

$d=\sqrt{(-2-2)^2+(-1-1)^2)$

$d=\sqrt{(-4)^2+(-2)^2)$

$d=\sqrt{16+4)$

$d=\sqrt{20}$

$d=2\sqrt{5}$

Length of half segment $=2\sqrt{5}$ units

∴ Length of segment = $2\times length\ of\ half\ segment= 2\times 2\sqrt5=4\sqrt5$ units

A bicycle has a listed price of $625.99 before tax. If the sales tax rate is 7.5%, find the total cost of the bicycle with sales

Serhud [2]

With tax, it would be 107.5% of 625.99. 107.5% is 1.075 in decimal form so you do 1.075(625.99). That gives the rounded answer of $672.94. :)
