What is the slope of the line graphed below? (3,3) (0,-6)

Mathematics

Burka [1]3 years ago

Answer:

The slope of the lines is 3.

Step-by-step explanation:

Since I can't actually graph it, we can make a table

x      y

3      3

0     -6

From 3 to -6, you subtract 9 (for the y section)

From 3 to 0, you subtract 3 (for the x section)

Now all you need to do is divide y by x

y/x = -9/-3 = 3

It's a positive 3, because two negatives times each other will always result in a positive.

Slope = 3

Hope this helped!

46) write the expression: The quotient of p and q is twelve less than three times the sum of P and q
katovenus [111]

Answer:

Step-by-step explanation:

p/q = 3(p + q) - 12

The quotient of p and q: p/q quotient means division

is means =

3(p + q) is three times the sum of p and q

3(p + q) - 12 twelve less than three times the sum of p + q

What is the x intercept that is perpendicular to y=4/3x+1 and passes through (-4,9)
kolezko [41]
Well, we know the line is perpendicular to that one above.... what is the slope of that one anyway?  well, notice, the equation is already in slope-intercept form   \bf y=\stackrel{slope}{\cfrac{4}{3}}x+1.

so, we're looking for the equation of a line perpendicular to that one, now, since that one has a slope of 4/3, a perpendicular line will have a negative reciprocal slope to that one, 

\bf \textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{4}{3}\\\\
negative\implies  -\cfrac{4}{ 3}\qquad reciprocal\implies - \cfrac{ 3}{4}

so, what is the equation of a line whose slope is -3/4 and runs through -4,9?

\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
&&(~ -4 &,& 9~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies -\cfrac{3}{4}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-9=-\cfrac{3}{4}[x-(-4)]
\\\\\\
y-9=-\cfrac{3}{4}(x+4)

now, the x-intercept for any function is found by zeroing out the "y" and solving for "x", thus

\bf y-9=-\cfrac{3}{4}(x+4)\implies 0-9=-\cfrac{3}{4}(x+4)\implies -9=-\cfrac{3x}{4}-3
\\\\\\
-6=-\cfrac{3x}{4}\implies -24=-3x\implies \cfrac{-24}{-3}=x\implies 8=x

x = 8, y = 0           ( 8 , 0 )

You run at a pace of 8.5 minutes per mile in a 26.2 mile marathon. How many minutes will it take finish?
algol [13]
8.5 minutes per mile is equivalent to 

17 minutes
----------------
  2 miles

and the reciprocal of that is


2 miles
-----------
17 min

Now multiply 26.2 miles by 

17 min                                   (17 min)* (26.2 mi)
------------ ,    obtaining         ---------------------------
 2 miles                                           2 mi

This simplifies to (17)(26.2)/2 minutes = 222.7 minutes, 

or

222.7 minutes        1 hr
-------------------- * ------------ = 3.7 hours
          1                  60 min
