y = - x -
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 1 ) and (x₂, y₂ ) = (2, - 5 )
m = = = -
the partial equation is
y = - x + c
to find c substitute either of the 2 given points into the partial equation
using (- 6, 1 ), then
1 = + c ⇒ c = 1 - = -
y = - x - ← equation of line
Answer:
(A) 450-3x
Step-by-step explanation:
Cuz I know the answer.
Answer:
(a) = 71 cm
(b) = 89 cm
Step-by-step explanation:
(a.)
perimeter of a rectangular field = 324 m
length (l) = 91 m
width (w) = ?
Now,
<em>Perimeter Of Rectangle </em>
<u>= <em>P = 2(l + w)</em></u>
= 2(91 + w) = 324m
= 182 + 2w = 324m
= 2w = 324 - 182m
= 2w = 142m
= w = 142/2
= w = 71
(b.)
area of rectangular painting = 5696 cm²
width (w) = 64 cm
length (l) = ?
Now,
<em>Area Of Rectangle </em>
A = <em><u>l × </u></em><em><u>w</u></em>
= l × 64 = 5696
= l = 5696/64
= l = 89 cm
<h2>
<em><u>VERIFICATION</u></em><em><u>:</u></em><em><u>-</u></em></h2>
FOR (a)
= P = 2(l + w)
<em><u>= P = 2(91 + 71) = 324 cm</u></em>
FOR (b)
= l × w
A = 89 × 64 = 5696
ANSWER
EXPLANATION
The given inequality is
The slope intercept form of the given inequality is given by,
Where m is the slope and c is the y-intercept of the corresponding linear equation.
So we make y the subject of the given inequality to obtain,
We now divide through by 2 to get,
Therefore the correct answer is option B
