Given the line 5x – 2y = 10, Find the equation of a parallel line that passes through the point (2, 3). Find the x- and y-intercepts of both lines. Plot the intercepts and use them to graph both lines on the same set of axes.

Answers

1) subtract 5x from both sides
2) you will be left with 2y= -5x +10
3) then you divide 2 from the three numbers
4) you will be left with y=-5/2x +5
your slope is -5/2x
and your y-intercept is 5
which means your point starts at (0,5) on the graph

flynn opens a saving account. In one 3 month period, he makes deposit of $75.50 and $55.25. He makes withdrawal of $25.15 and $18.65. His balance at the end of the 3 month period is $210.85. Explain how you can find his initial deposit amount?

Answers

By adding all of the amounts up: 75.00+55.25= 130.25, afterwords you need to add up the amount that Flynn spent, which is 25.15+18.65= 43.80, Once you have these two numbers. You need to subtract them from each other which looks like this: 130.25-43.80=86.45, then by subtracting that number from the last amount: 210.85-86.45=124.4.
The initial deposit is: 124.4
And to check your answer, you have to add 130.25+124.4=254.65, and then: 254.65-43.80= 210.85.

x=initial deposit amount.
we have to add to the initial deposit amount the incomes and subtract the withdrawal
x+($75.5+$55.25)-($25.15+$18.65)=$210.85
Now we solve this equation.
x+$130.75-$43.8=$210.85
x+$86.95=$210.85
x=$210.85-$86.95
x=$123.9

Answer: his initial deposit amount is $123.9
