Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth.
lakkis [162]
\sf 5x+2y=21
\sf -2x+6y=-34

We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':

\sf -2x+6y=-34

Subtract 6y to both sides:

\sf -2x=-6y-34

Divide -2 to both sides:

\sf x=3y+17

Plug in 3y + 17 for 'x' in the first equation:

\sf 5x+2y=21

\sf 5(3y+17)+2y=21

Distribute 5:

\sf 15y+85+2y=21

Combine like terms:

\sf 17y+85=21

Subtract 85 to both sides:

\sf 17y=-64

Divide 17 to both sides:

\boxed{\sf y\approx -3.8}

This is the y-coordinate of the solution.

Ashley charges $6 for a bracelet and 12$ for a necklace. She earned $168. Use b for bracelets and n for necklaces, and write an
yarga [219]

Answer:

Step-by-step explanation:

let the number of bracelet be b

Let the number of necklace be n

If Ashley charges $6 for a bracelet , the total amount charged for b bracelets will be 6b

If she charge $12 for a necklace, the total amount for n necklace will be 12n

If she earned $168 in total, then:

6b + 12n = 168

Divide through by 6

b + 2n = 28

Hence the equation for this situation is b + 2n = 28

Next is to solve for b:

Make b the subject of the formula:

b + 2n = 28

subtract 2n from both sides

b + 2n - 2n = 28 - 2n

b = 28 -2n

Hence the function for b will  be b = 28-2n
