Answer:
x=9.064
Step-by-step explanation:
![x-4=13(6x-54) / multiply by 13 \\ x-4=78x-702\\x-4-78x=-702\\-77x=-702+4\\-77x=-698 / divide both sides by -77\\x=\frac{-698}{-77} = 9\frac{5}{77} = 9.064\\x=9.064](https://tex.z-dn.net/?f=x-4%3D13%286x-54%29%20%2F%20multiply%20by%2013%20%5C%5C%20x-4%3D78x-702%5C%5Cx-4-78x%3D-702%5C%5C-77x%3D-702%2B4%5C%5C-77x%3D-698%20%2F%20divide%20both%20sides%20by%20-77%5C%5Cx%3D%5Cfrac%7B-698%7D%7B-77%7D%20%3D%209%5Cfrac%7B5%7D%7B77%7D%20%3D%209.064%5C%5Cx%3D9.064)
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2
F (x)= (x+1)(x-1)(x^2-2x-2)
Answer:
a line parallel to this line would be y=3
Step-by-step explanation:
parallel lines have the same slope, but different y-intercepts.
the slope of the line that passes through (4, 9) and (11, 9) is 0.
the equation is y = 9.
and that is identical to y = 3, because they both do not have a slope; they both form straight horizontal lines across the graph.
