Y=2x+6 We know the y intercept is +6 so we still can’t eliminate any of the options. We know it can’t be 1/3x or 1/2x because the y value is greater than the x value. (6)(2)+6=18
The correct answer is 3,520 people purchase something. Explanation: 4/10 = .4, so 8,880 x .4 = 3,520
Answer: x y (y - x) (x + y)
-x y (x - y) (x + y)
x (y^3 - x^2 y)
Real roots:
x = 0
y = 0
Roots:
y = -x
y = x

Step-by-step explanation:
Answer:
1. 2w + 3p = 7.05
2. p = 1.35
w = 1.50
p = 1.35
- The solution means that a bottle of water costs $1.50 and a bag of pretzels costs $1.35
Explanation
1) Translate the verbal language to algegraic language to create the equations which you can solve.
w = cost of one bottle of water
p = cost of one bag of pretzels
the cost of 2 bottles of water: 2w
the cost of 3 bags of pretzels: 3p
the cost of 2 bottles of water and 3 bags of pretzels is $7.05:
2w + 3p = 7.05 Equation 1
the cost of a bag of pretzels is $ 1.35: p = 1.35 Equation 2
1. 2w + 3p = 7.05
2. p = 1.35
2) Solve the system using substitution method: substitute p with 1.35 in the first equation:
3) Steps to solve the equation:
- Simplify: 2w + 4.05 = 7.05
- Subtract 4.05 from both sides: 2w = 3
- Divide both sides by 2: w = 3/2 = 1.50
Answer: you have found the costs of both a bottle of water and a bag of pretzels, which, repectively, are $ 1.50 and $ 1.35
