Hi there!

Your graphic organizer would be: 7y + 6y = 59 And 5y + 4x = 41

6x + 7 (-4x divided by 5 + 41 divided by 5) which gives you 59

2x divided by 5 would give you the answer of 8/5

Now, 2x = 8

Divide by two on each of your sides!

2x divided by 2 gives you one

8 divided by 2 equals to four

X-intercept: $4$

Now, to find the y-intercept

Y = -4x divided by 5 + 41 divided by 5

Convert it to: -4. Divided 5 (5) + 41 divided 5 would give you 5

Y-intercept: $5$

$Answer: \right \{ {{x=4} \atop {y=5}} \left.$

Good luck on your assignment and enjoy your day!

The product of two integers is eighty,their quotient is five.Write both integers in numerical order and separated by a comma,no

Goryan [66]

SOLUTION

Let the two integers be x and y.

Now, the product of x and y, is 80, that is

$\begin{gathered} x\times y=80 \\ xy=80\ldots\ldots\text{.equation 1} \end{gathered}$

The quotient of x and y is 5, that is

$\begin{gathered} x\div y=5 \\ \frac{x}{y}=5\ldots\ldots\ldots\ldots\text{.}\mathrm{}\text{equation 2} \end{gathered}$

From equation 2, make x, the subject, we have

$\begin{gathered} \frac{x}{y}=5 \\ \text{cross multiplying } \\ 5\times y=x \\ x=5y \end{gathered}$

Now substitute the x for 5y into equation 1, we have

$\begin{gathered} xy=80 \\ 5y\times y=80 \\ 5y^2=80 \\ \text{dividing by 5} \\ y^2=\frac{80}{5} \\ y^2=16 \\ \text{take square root of both sides } \\ \sqrt[]{y^2}=\sqrt[]{16} \\ \text{square cancels root} \\ y=4 \end{gathered}$

Now substitute y for 4 into any of the equations.

Let us use equation 1 again, we have

$\begin{gathered} xy=80 \\ x\times4=80 \\ 4x=80 \\ x=\frac{80}{4} \\ x=20 \end{gathered}$

Hence the answer is 4, 20
