X= [ 2*(-3)+ 3*(2)/( 2+3) = 0
y = [ 1*3+ 6*2 ]/2+3 = 3
so P is( 0,3 )
if it lies on the line x+ 5y = 15 then this point should satisfy the equation
so 0 + 5*3 = 15
so Plies on the given line x - 5y + 15 = 0
Answer:
The number of Pencils purchased and the cost of pencils has a proportional relationship.
Step-by-step explanation:
In order to figure out if a proportional relationship between two variable exists,
- All you need is to check if relationships between two variables have equivalent ratios.
- If the ratios between two variables is same, it means a proportional relationship between two variable exists.
Lets take a simple example:
As
2/10 = 9/45 is a TRUE proportion.
The reason is that both fractions reduces to 1/5, and
because 10 × 9 = 2 × 45.
So
In the equation it needs to be determined whether the number of Pencils purchased and the cost of pencils represent a proportional relationship?
When we are given that:
In other words each pencil costs $0.25.
As each pencil costs $0.25, it means:
2 pencils cost $0.5, 3 pencils cost $0.75, and 4 pencils cost $1 and so on.
Thus
Cost ÷ No of Pencils Purchased = 0.25 ÷ 1 = 0.5 ÷ 2 = 0.75 ÷ 3 = 1 ÷ 4
And the ratio is same.
i.e. cost per pencil = 0.25 : 1
As all of the ratios are same, we can determine that it has a proportional relationship.
Therefore, the number of Pencils purchased and the cost of pencils has a proportional relationship.
The answer is 41 inches. Since <span>△HKS∼△DLY, so the measurements of the angles are just the same. So if the sides are 15 x 20 x 32. Then to get the sides of the other triangle is simply adding what is the measurement of the sides from the first triangle. so it is 24 x 29 x 41. So the answer of DY is equal to 41 inches.</span>
Since the break even point at 50000
Devises, the company would spend 25 months before they make profit to sell 50000
50,000÷2,000=25 months
The least amount she must save is $190
work: 475-285 =190
