Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
Our first point, A, is at (1, 1) and our second point, B, is at (-2, 8).
Let's let A(1, 1) be (x₁, y₁) and B(-2, 8) be (x₂, y₂). Substitute this into the distance formula:
Subtract:
Square:
Add:
This cannot be simplified.
So, the distance between the two points is √58 or about 7.6 units.
And we're done!
So... where's my cookie :)?
Answer:
3 pounds of peanuts and 2 pounds of cashews
Step-by-step explanation:
Let x be the pounds of peanuts and y be the pounds of cashews
Greta wants to make 5 pounds of a nut mix using peanuts and cashews.
So, ----- A
Cost of 1 pound of peanuts = $4
Cost of x pounds of peanuts = 4x
Cost of 1 pound of cashews = $9
Cost of y pounds of cashews = 9y
Her budget requires the mixture to cost her $6 per pound
So, cost of mixture of x pounds of peanuts and y pounds of cashews is 6(x+y)
So, --- B
Plot A and B
---Blue
---Green
Refer the attached figure
Intersection point = (x,y)=(3,2)
Hence she should use 3 pounds of peanuts and 2 pounds of cashews
