Answer:
x = 7
Explanation:
We are given
22 + 54x = -20 + 60x
We can add 20 on both sides using the Addition Property of Equality
42 + 54x = 60x
Subtract both sides by 54x using the Subtraction Property of Equality
42 = 6x
Divide both sides by 6 using the Division Property of Equality
x = 7
The answer is (1,-4)
Remember that the vertex is the center of the parabola.
Answer:
The number of nickel coins is 10 and the number of quarter coins is 5
Step-by-step explanation:
<u><em>The correct question is</em></u>
Mary has 15 coins with the total value of $1.75 if the coins are nickels and quarters how many of each kind are there
Let
x ----> the number of nickel coins
y ----> the number of quarter coins
Remember that


we know that
Mary has 15 coins
so
-----> equation A
The total value of the coins is $1.75
so
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (10,5)
therefore
The number of nickel coins is 10 and the number of quarter coins is 5
