A jewelry store is selling necklaces and bracelets. Each necklace yields a profit of $8 and each bracelet yields a profit of $6.

marta [7]

n = necklace

b = bracelet

n +b =120

n = 120-b

3.50n + 2.50b = 330

11n + 5b = 880

3.5(120-b) +2.5b=330

420-3.5b + 2.5b = 330

420 -b = 330

-b = -90

B =90

N = 30

3.5*30= 105

2.5*90 = 225

225 +105 = 330

11*30 = 330

90*5 = 450

450 +330 = 780

90 bracelets and 30 necklaces

1) The standard form of a linear equation is written as .

Helen [10]

Answer:

$\displaystyle y=-\frac{a}{b}x+\frac{c}{b}$

Step-by-step explanation:

The equation of the line, expressed in slope-intercept form is:

$y=mx+y_o$

Where m the slope and yo the y-intercept.

Since we are given the line in standard form:

ax+by=c

To find the slope-intercept form, we just solve it for y:

$\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}$

Comparing the last equation with the slope-intercept form:

$\displaystyle m=-\frac{a}{b}$

$\displaystyle y_o=\frac{c}{b}$
