What is the equation in standard form of the line shown on the graph?
Andreyy89

well, let's check the graph, and use two points off of it..hmmmm it passes through (4, 0) and it also passes through (0, -4).

so, what would be the equation of a line that passes through those two points?

keeping in mind that

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-4}) ~\hfill slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-4-0}{0-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-0=1(x-4)\implies y=x-4 \\\\\\ -x+y=-4\implies \stackrel{\textit{standard form}}{x-y=4}\\\hspace{34em}

Alex73 [517]
Final value = Initial value × (mutiplier)^n

We have;
Initial value = 9300
Multiplier = 100%+3.2% = 103.2% = 1.032
Number of quarters in a year = 4

Substitute all values into the formula, we have
Final Value = 9300 (1.032)^{4}=10548.77 rounded to two dp

Elijah and his sister went to the movies. They had 34 altogether and spent 9.50 per ticket. Elijah and his sister bought the sam
Zarrin [17]

Answer:

The Inequality to find the amount of money they spent on snack is 2(9.5+x)\leq 34

Maximum amount each person can spent on snack is 7.5.

Step-by-step explanation:

Given:

Total Money they had = 34

Cost of each ticket = 9.5

Number of persons = 2

Let the cost of snacks bought by each be x.

We need to write inequality and solve for the amount each persons spent on snacks.

Solution:

Now we can say that;

Number of persons multiplied by sum of Cost of each ticket and Cost of each person spent on snack should be less than or equal to Total money they had.

framing in equation form we get;

2(9.5+x)\leq 34

Hence the Inequality to find the amount of money they spent on snack is 2(9.5+x)\leq 34

On Solving the above Inequality we get;

2(9.5+x)\leq 34\\\\19+2x\leq 34

Now By Using Subtracting property of Inequality we will subtract both side by 19 we get;

19+2x-19\leq 34-19\\\\2x\leq 15

No By Division Property of Inequality we will divide both side by 2 we get;

\frac{2x}{2}\leq \frac{15}{2}\\\\x\leq 7.5

Hence maximum amount each person can spent on snack is 7.5.

Interpreting the solution we get;

Now Cost of 1 ticket = $9.5

Number of person = 2

So total cost of ticket = $19

Total money they have = $34

Money left = Total money - total cost of ticket =$34 -$19 = $15

Amount of money left = $15

Now each buys the same snack.

So maximum amount of money each can spent on snack = $7.5
