Answer:

X=4, y=-1

Step-by-step explanation:

-3x+10y=2 multiple by 3

-3x+3y=9 multiply by 10

9x+30y=6

30x+30y=90

Subtract equation 1 from 2

30x-9x+30y-30y=90-6

21x+0=84

21x=84

Divide both side by 21

X=4

Substitute 4 for x in equation 1

3x+10y=2

3(4)+10y=2

12+10y=2

10y=2-12

10y=-10

Divide both side by 10

Y=-1

Answer:

(-4,-1)

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

Shelby is starting a business selling handmade necklaces. She has decided to invest an initial amount of $172 for advertising, a
8_murik_8 [283]

Answer:

-43 necklaces.

-total expenses=Sales=$473

Step-by-step explanation:

The breakeven point is the point where the sales revenue equals the expenditure.

-The fixed expenses is $172

-Let x be the number of necklaces sold, the breakeven point is expressed as:

Sales= Expenses\\\\11x=7x+172\\\\4x=172\\\\x=43

Hence, Shelby has to sell 43 necklaces to breakeven.

#The expenses at the breakeven point is:

E=7x+172\\\\=7\times43+172\\\\=473

Hence, expenses at breakevent point is $473

#Sales is equal to expenses at this point, hence, sales of $473

What is an equation of the line that is parallel to y=-5x+6 and passes through the point (-4,-1)​
marin [14]

Answer:

y= -5x - 21

Step-by-step explanation:

parallel lines have the same slope, so you know the slope.

you need to use the point slope formula y-y1=m(x-x1)

with this equation, this looks like y - -1 =- 5(x - -4)

double negatives are positives, so to keep this easier on the eyes, let's make it y + 1= -5(x + 4)

distribute the -5. you should get y + 1 = -5x - 20

subtract 1 to move it from the left side to the right and you get your answer!

y = -5x - 21
