The table below shows the velocity y, in miles per minute, of a toy car at different times x, in minutes:
garik1379 [7]
The value of the slope of the graph of the velocity versus time between 10 minutes and 20 minutes would be .06. I got to this answer by getting the changes in the rise (y) over run (x) of the table:

slope = y2- y1 / x2-x1
= .8-.2 / 20-10 mi / min
= .6 / 10 min
= .06 

Then for the follow up question, the slope represents the distance traveled of the toy car (in miles).

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly? x = StartFraction negative
AnnZ [28]

Answer:

x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}

Step-by-step explanation:

Recall that the quadratic formula gives you the pattern to follow in order to find the solutions to a quadratic equation of the form: ax^2+bx+c=0

It tells us that we need to use the parameters a,\, b, and c in the following formula in order to get the answers for the x-values that solve it:

x=\frac{-b+/-\sqrt{b^2-4\,a\,c} }{2\,a}

so, in our case, a=1, b=-9, and c=-20

then, replacing these values in the formula, we obtain:

x=\frac{-b+/-\sqrt{b^2-4\,a\,c} }{2\,a}\\x=\frac{-(-9)+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}\\x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}

Which looks like the third expression you are listing (although it is a little hard to read)

“The line that passes through point H has the equation y=-2x -3”
Katena32 [7]

Answer:

Step-by-step explanation:

Generally

The equation of a line is given as

y = mx + c

Where

m is the slope

c is the intercept on y axis

Note: if two lines are parallel, their slopes are equal

I.e M1 = M2 =m

If two lines are perpendicular, then, their slopes are given as

M2 = - 1/M1

Given that,

The line that pass through the point H has an equation

y = -2x-3

From equation of a line, we know that, the slope of the line that passes through H is -2

m = -2

We want to find the equation of a line parallel to line that passes through H

If the line we want to find is parallel to the given line, then, their slope are equal,

So, the slope of line that passes through point G is m=-2

So, the equation of the line that passes through point G is

y = mx + c, m=-2

y = -2x + c

So, we need to find c, so, using the point G it passes through,

G = (2,1) I.e x = 2 and y = 1

y = -2x + c.

1 = -2(2) + c

1 = -4 + c

1+4 = c

c = 5

So, the equation of the line that passes through G becomes

y = -2x + 5
