Step-by-step explanation:

Southville is due south of Portland and Westfield is due west of Portland. So the three cities form a right-angled triangle on a map.

The distance between Southville and Westfield = sqrt( 57^2 + 76^2)

= 95 miles

A squared + B squared = C squared

57 squared + 76 squared =

(Distance between Southville and Westfield) squared

square root of (3249 + 5776) = Distance between Southville and Westfield

square root of 9025 = Distance between Southville and Westfield

Distance between Southville and Westfield = 95 miles

Hope this helps! God bless :-)

The expression below can be written in simplest form as<br> 4(2x-5)+7(x+2)

Andreas93 [3]

4(2x-5)+7(x+2)

bracket means multiplying

do 4(2x+5) first

4*2x=8x

4*-5=-20

7*x=7x

7*2=14

8x-20+7x+14

do the x first

8x+7x=15x

-20+14=-6

answers: 15x-6 or -6+15x

What is the slope of this graph? −14 4 14 −4 Number graph ranging from negative 10 to 10 on both the x and y axis. A line passes

spin [16.1K]

The slope of this graph is - 4

Step-by-step explanation:

The slope of a line is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where

$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points on the line
The slope of a horizontal line is zero
The slope of a vertical line is undefined

∵ The graph is a line

∵ The line passes through points (1 , -2) and (0 , 2)

∴ $x_{1}$ = 1 and $x_{2}$ = 0

∴ $y_{1}$ = -2 and $y_{2}$ = 2

- Substitute these values in the rule below

∵ $m=\frac{y_{2}-y_{1}}{x_{2}-x_{2}}$

∴ $m=\frac{2--2}{0-1}=\frac{4}{-1}$

∴ m = - 4

The slope of this graph is - 4
