Answer:
x = 2
Step-by-step explanation:
6x - 5 = 13 – 3x
Add 3x to both sides
6x + 3x - 5 = 13 - 3x + 3x
9x - 5 = 13
Add 5 to both sides
9x - 5 + 5 = 13 + 5
9x = 13+5
9x = 18
Divide both sides by 9
9x/9 = 18/9
x = 2

The number of times a graph crosses the x axis is the same as asking how many zeroes has the function represented by that graph.
The number of zeroes is given by the power of the independent variable, in this case x.
Given that the maximum power of x is 2, then the function has 2 zeroes and the graph crosses the x axis 2 times
Answer:
200$
Step-by-step explanation:
In this case, we already know the ratio between the savings and the spendings and it's 3:5.
This means that for every 3$ saved, Sam spents 5$.
Then, we only need to do a simply rule of 3, to stablish the amount spended.
If:
120 ---------> 3
X ------------> 5
Solving for X, we have:
120/X = 3/5
X = 120 * 5 / 3
X = 600 / 3
X = 200$
If you want to verify that this calculation is correct, then do the ratio between 120 and 200. If the ratio is 3:5 is correct. Here's the demostration:
120/200 --->simplified by 10: 12/20 ------->simplified by 4: 3/5
