A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?

Gwar [14]

Answer:

The slope of line for given points is $\frac{12}{17}$

Step-by-step explanation:

Given points of line as :

A = ( - 7 , 15 ) i, e $x_1$ = - 7 , $x_1$ = 15

B = ( 10 , 27 ) i.e $x_2$ = 10 , $y_2$ = 27

Let The slope of line be m

So , The slope with two points is given as equation

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

Or, m = $\frac{27 - 15}{10 + 7}$

Or, m = $\frac{12}{17}$

Hence The slope of line for given points is $\frac{12}{17}$ . Answer

In a store, 1 can of soup costs $1.80. The store also sells a pack 6 cans of soup. A customer who buys 1 pack saves 15% compared

Likurg_2 [28]

Answer:

$\$1.62$

Step-by-step explanation:

Let

x-----> the cost of one pack of 6 cans of soup

step 1

Find the cost of 6 cans of soup

$6(1.80)=\$10.8$

step 2

Find the cost of one pack of 6 cans of soup

$100\%-15\%=85\%=85/100=0.85$

$x=0.85(\$10.8)=\$9.18$

step 3

Find the money saved

$\$10.8-\$9.18=\$1.62$

Given Bold u equals negative Bold i plus Bold j, Bold v equals 10 Bold i minus 2 Bold j, and Bold w equals negative 8 Bold j,

OverLord2011 [107]

Answer: u.(v+w) = -20

Step-by-step explanation:

Given;

u = -i+j

v = 10i-2j

w = -8j

v+w = 10i-2j +(-8j)

v+w = 10i-10j

u .(v+w) = (-i+j).(10i-10j)

= -1×10 + 1 ×-10

= -10-10

u.(v+w) = -20
