(01.04) Solve the following for y: 4x + 2y = −2 (6 points)

Marat540 [252]

Factor out the common term 2

2(2x + y) = -2

Divide both sides by 2

2x + y = -1

Subtract 2x from both sides

y = -1 - 2x

2. What is an equation line that pass-cs through the point (3,-1) and h (4)

joja [24]

Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b

y=2x-7 is equation

answer is number 4

PLEASE HELP

1. y=6

2. y=-12

Step-by-step explanation:

1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.

It is given that

y varies inversely as x

IT will be written as:

y∝1/x

Removing the proportionality symbol

y=k/x

Given

y=3 , x=-2

Putting the values

3=k/-2

k=3*-2 = -6

The equation will be:

y=-6/x

So,

When x=-1

$y=\frac{-6}{-1}\\y=6$

2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4

y is directly proportional to x

y∝x

y=kx

Given

y=15, x=-3

Putting the values

$y=kx\\15=-3k\\k=\frac{15}{-3}\\k=-5\\The\ equation\ will\ be:\\y=-3xNow,\\x=4\\y=-3(4)\\y=-12$

Hence,

1. y=6

2. y=-12

For a production of sweeney todd in las vegas, orchestra seats cost $42 and mezzanine seats cost $25. if a group of 14 people sh

Lesechka [4]

Answer: 8 orchestra seats and 6 mezzanine seats.

Step-by-step explanation:

Let be "o" the number of orchestra seats they bought and "m" the number of mezzanine seats they bought.

Set up a system of equations:

$\left \{ {{42o+25m=486} \atop {o+m=14}} \right.$

You can apply the Substittution Method to solve the system of equations:

1. Solve for "o" from the second equation:

$o=14-m$

2. Substitute it into the first equation and solve for "m":

$42(14-m)+25m=486\\\\588-42m+25m=486\\\\-17m=-102\\\\m=\frac{-102}{-17}\\\\m=6$

3. Substitute the value of "m" into $o=14-m$ and evaluate, in order to find the value of "o". This is:

$o=14-6\\\\o=8$
