Through (-1,-4) parallel to y=-x -3

1 answer:

8 0

y - y₁ = m(x - x₁)
y - (-4) = 1(x - (-1))
 y + 4 = 1(x + 1)
 y + 4 = 1(x) + 1(1)
 y + 4 = -x + 1
 - 4 - 4
 y = -x - 3

Step-by-step explanation:

cost of 1 kg of jam = x

cost of 1 kg of butter = y

3x + 2y = 29 .....1

6x + 3y = 54 .....2

.....1 × 2 both sides of equation

6x + 4y = 58 .....3

.....3 - ......2

y = 4

replace y = 4 in 1......

3x + 8 = 29

x = 7

Greek architects considered a rectangle whose length was approximately 1.6 times its width to be the most visually appealing. fi

Oliga [24]

Let
x-------------> the length of a rectangle
y-------------> the width of a rectangle
we know that
x+y=130-----------> equation 1
and
x=1.6y--------------> equation 2

I substitute 2 in 1
(1.6y)+y=130-------------> 2.6y=130------------> y=130/2.6------> y=50 ft
x=1.6y--------> x=1.6*50---------> x=80 ft

the answer is
the length is 80 ft
the width is 50ft
