Answer:

1) Slope of the line  y = \frac{-3}{2}

2)Slope of the line m = 2

3) slope of the line m = -5

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that equation of the straight line 3 x+2 y =0

The slope - intercept form    y = mx +c

                                              2 y = - 3x

                                              y = \frac{-3}{2} x

Slope of the line  y = \frac{-3}{2}

<u><em>Step(ii):-</em></u>

Given that equation of the straight line 2 x- y = 3

The slope - intercept form    y = mx +c

                                              y = 2x -3

slope of the line m = 2

<u><em>Step(iii):-</em></u>

Given that equation of the straight line 5 x + y = 10

The slope - intercept form    y = mx +c

                                              y = -5x +10

slope of the line m = -5

Help!! whats the answer? and how do I solve!! :(
Sever21 [200]
I think the answer is 20.25 because when solving for the area of a triangle you do 1/2 base times height and so the equation would be
1/2(9)(4.5)
you would start by doing 9(4.5) which equals 40.5
then you would divide by 1/2 which equals 20.25
hope this helps:)

Romb ma obwód równy 32 cm. Jakie jest pole tego rombu, jeżeli jego wysokość ma 3 cm?
Goshia [24]

Answer:

24 cm²

Step-by-step explanation:

Z zadanego powyżej pytania uzyskano następujące dane:

Obwód (obwód) = 32 cm

Wysokość (h) = 3 cm

Obszar rombu (A) =?

Następnie określimy długość boku rombu. Można to uzyskać w następujący sposób:

Obwód, czyli obwód (P) = 32 cm

Strona (y) =?

P = 4 s

32 = 4 s

Podziel obie strony przez 4

s = 32/4

s = 8 cm

Stąd długość boku rombu wynosi 8 cm

Na koniec określimy obszar rombu w następujący sposób:

Długość boków = 8 cm

Wysokość (h) = 3 cm

Obszar rombu (A) =?

A = sh

A = 8 × 3

A = 24 cm²

Dlatego obszar rombu jest

24 cm².
