Find two numbers whose sum is 20 and difference is 1

1 answer:

6 0

Divide 20 by 2
20/2 = 10
Add and subtract 0.5* from 10
10 + 0.5 = 10.5
10 - 0.5 = 9.5
Those two numbers are your answer.

*The reason why we used 0.5 because the difference is 1, so divide 1 by 2.

Have an awesome day! :)

17) The coordinates of quadrilateral EFGH are E(7, 7), F(4, 8), G(2, 2), H(7, 2). Show that EF is perpendicular to FG.

strojnjashka [21]

Answer:

see explanation

Step-by-step explanation:

first we calculate the slopes of EF and FG using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ = E (7, 7 ) and F (4, 8 )

$m_{EF}$ = $\frac{8-7}{4-7}$ = $\frac{1}{-3}$ = - $\frac{1}{3}$

repeat with (x₁, y₁ ) = F (4, 8 ) and (x₂, y₂ ) = G (2, 2 )

$m_{FG}$ = $\frac{2-8}{2-4}$ = $\frac{-6}{-2}$ = 3

if 2 lines are perpendicular then the product of their slopes = - 1

here

$m_{EF}$ × $m_{FG}$ = - $\frac{1}{3}$ × 3 = - 1

then EF is perpendicular to FG
