x+y=46 and 1.75x+2y=89.50 can be used to determine the number of pounds of blueberries sold and the number of pounds of apples sold, where x represents the pounds of blueberries sold and y represents the pounds of apples sold.
Step-by-step explanation:
Cost of one pound of blueberries = $1.75
Cost of one pound of apples = $2
Total worth = $89.50
Total sold = 46 pounds.
Let,
x be the pounds of blueberries sold.
y be the pounds of apples sold
According to given statement;
x+y=46 Eqn 1
1.75x+2y=89.50 Eqn 2
x+y=46 and 1.75x+2y=89.50 can be used to determine the number of pounds of blueberries sold and the number of pounds of apples sold, where x represents the pounds of blueberries sold and y represents the pounds of apples sold.

Answer:
Domain for this particular relation (which is a function) is:
{-4,-1,0,2,7}.
This is choice A.
Step-by-step explanation:
The domain is every number in the first circle (reading from left to right) that has an arrow drawn from it.
The range is every number in the second circle (reading from left to right) that has an arrow drawn to it.
So the domain is {-4,-1,0,2,7} and the range is {-5,0,1,2,4}.
(They say this relation is a function because every element in the domain has no more than one arrow drawn from it.)
Answer:
Step-by-step explanation:
Simplifying
2x + 4y = 13
Solving
2x + 4y = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 13 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 13 + -4y
2x = 13 + -4y
Divide each side by '2'.
x = 6.5 + -2y
Simplifying
x = 6.5 + -2y

2^-1 = 1/2 : .
1/2 (6x-12)
=1/2* 6x - 1/2* 12
Basically ure dividing everything inside the brackets by two. Or multiplying by a half which is essentially the same thing.
