Answer:

A and B

Step-by-step explanation:

Basically all you have to do is combine those equations. How do you do that? You add/subtract the equations from each other, OR use substitution. It's hard to explain I recommend searching it up.

However, in this equation this is not what they are asking for. Only ONE equation has a solution when combined/substituted. Some have false solutions such as 3=0, which is not true. Some have infinite solutions where every number works.

Solving A:

This works because it actually gives us the value of y and x instead of giving us an incorrect statement.

Solving B:

This works as well!

Solving C:

This has no solution. It doesn't work and it ends up with 0 = -6, which is not true.

Solving D:

This has more than 1 solution.

Solving E:

This does not work, it has no solutions. It ends up with 0 = -2.

In this equation the constant is -4.

Answer:

change it into slope intercept form: y=3/2x-5

Step-by-step explanation:

the slope is 3/2

Answer:

m = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

This is the answer because:

1) Use the slope-intercept form: y = mx + b to find the slope

1. The slope intercept form is y = mx + b where m is the slop and b is the y-intercept.

2. Subtract 3x from both sides of the equation:

-2y = 10 - 3x

3. Divide each term by -2 and simplify:

[tex]y=\frac{3}{2} -5[/tex]

4. Using the slope-intercept form, the slope is [tex]\frac{3}{2}[/tex]

Therefore, the answer is [tex]\frac{3}{2}[/tex]

Hope this helps! :D

Answer:

a = 16

b = -6

Step-by-step explanation:

a + 2b = 4

2a + b = 26

2a + 4b = 8

2a + b = 26

3b = -18

b = -6

a + 2(-6) = 4

a - 12 = 4

a = 16

Answer:

x = -5  y = -3

Step-by-step explanation:

-3x + 2y = 9

multiply the 2nd equation by 3 to set it up for elimination

3(x - 3y)= 3(4)

3x-9y = 12

so now combine both to add

-3x + 2y = 9

3x - 9y = 12

Adding both gives you

-7y = 21

divide both by -7 and you get

y = -3

and you substitute y back into equation to get x

x - 3 (-3) = 4   gives you

x + 9 = 4

x = 4 - 9

x = -5

Rahan doesn't have enough money that'll be required in buying the jacket.

Total Amount with Rahan = $200

Total amount of expenses = (1 × $60) + (3 × $25) + $80

= $60 + $75 + 80.

= $215

In this case, since Rahan has $200, then he doesn't have enough money that he'll use in buying the jacket.

Answer:

The number of games that need to be sold to the retailer in order for the profit to be about equal is approximately 555 games

Step-by-step explanation:

The given parameters are;

The net profit at which each game is sold to a retailer = $9.90

The net profit at which each game is sold at the factory outlet  = $10.99

The number of units sold by the outlet = 500

The amount in profit from selling at the factory outlet = 500 × $10.99 = $5,495.00

The number of games that need to be sold to the retailer in order for the profit to be about equal is given as follows;

Let "x" represent the number of games that need to be sold to the retailer in order for the profit to be about equal

Therefore, we have;

x × $9.90/game = $5,495.00

x = $5,495.00/($9.90/game) = 555.[tex]\overline {05}[/tex] games ≈ 555 games

Therefore, the number of games that need to be sold to the retailer in order for the profit to be about equal = x ≈ 555 games.

Answer:

23º = x

Step-by-step explanation:

One straight line is ALWAYS 180º

(called a linear pair)

So your equation is

157º + x = 180

subtract x on both sides

and you get

23º

That is a question about angles.

The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.

So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:

[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]

Therefore, the missing angle is 23°.
