Answer:
a. sami eats 7/12 slices
b. the ratio of slice sami eats to lynn eats is 7:5
Step-by-step explanation:
Answer: 2y + 5x + 16 = 0
Step-by-step explanation:
To solve this you need to understand the principle/ conditions for parallelism and perpendicularity.
for two lines to be parallel to each other, their gradients or slopes (m) must be equal, that is m₁ = m₂
Now from the given equation,
5x + 2y = 14 , we need to rearrange it to conform to the equation of a straight line so that the gradient could be established. ie
y = mx + c where m is the gradient
2y = -5x + 14
y = -5x/2 + 14/2
y = ⁻⁵ˣ/₂ + 7 , therefore , m₁ = ⁻⁵/₂ and m₂ = ⁻⁵/₂ ( parallelism Rule )
The next step is to find the value of C using the coordinate ( -2, -3 )
-3 = ⁻⁵/₂ ˣ ⁻² + C,
-3 = ¹⁰/₂ + C
-3 = 5 + C
C = -8.
Now to find the equation of the line that passed through the coordinate
y = mx + c
y = ⁻⁵ˣ/₂ - 8
2y = -5x - 16
2y + 5x + 16 = 0.
