Find the x- and y-intercepts 3x+y=5
vlada-n [284]

The x - intercept is (\frac{5}{3}, 0) and y - intercept is (0, 5)

<h3><u>Solution:</u></h3>

Given that : 3x + y = 5

<em><u>To find: x - intercept and y -intercept</u></em>

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x

3x + 0 = 5

3x = 5

x = \frac{5}{3}

Therefore the x - intercept is (\frac{5}{3}, 0)

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y

3(0) + y = 5

y = 5

Therefore y - intercept is (0, 5)

Sarah is selling bracelets and earrings to make money for summer vacation. The bracelets cost $2 and the earrings cost $3. She n
vivado [14]

Sarah is selling bracelets. The inequalities are a > 10 and 2a + 3b ≥ 60.

<u>Solution:</u>

Given, Sarah is selling bracelets and earrings to make money for summer vacation.  

bracelets cost = $2

earrings cost = $3  

She needs to make at least $60.  

Sarah knows she will sell more than 10 bracelets.  

We have to write inequalities

Now, according to given information,  

Total money ≥ $ 60

Money earned from bracelets + money earned by earrings ≥ 60

2 x number of bracelets + 3 x number of earrings ≥ 60

2a + 3b ≥ 60  

[ where a is number of bracelets and b is number of earrings]

And, number of bracelets is more than 10 ⇒ a > 10

Hence, the inequalities are a > 10 and 2a + 3b ≥ 60
