Answer:

12) y=3x-15

14) y=-1/2x

16) y=13x-105

Step-by-step explanation:

Parallel lines always have the same slopes but different y-intercepts. So, we can make the equation (b is y-intercept of new equation):

12) y=3x+b

14) y=-1/2x+b

16) y=13x+b

now, we can plug in each of the coordinates given to these equations.

12) (4,-3): 4 is x, -3 is y.

       -3=3(4)+b

      simplify: b= -15

14) (-4,2): -4 is x, 2 is y

      2=-1/2(-4)+b

        simplify: b=0

16) (9,12): 9 is x, 12 is y

       12=13(9)+b

       simplify: b=-105

Now, plug in those numbers to your equation for b value.

12) y=3x-15

14) y=-1/2x

16) y=13x-105

*for 14 we don't need to write anything after -1/2x because b=0*

Answer:

-1/5

Step-by-step explanation:

Line is passing through the points [tex] (-2, \:3)=(x_1, \:y_1) \:\&\: (3, \:2)=(x_2, \:y_2) [/tex]

Slope of line

[tex] = \frac{y_1 - y_2} {x_1 - x_2} \\\\=\frac{3 - 2}{ - 2 - 3} \\ \\ = \frac{1}{ - 5} \\ \\ = - \frac{1}{5} [/tex]

Answer:

x = 1 & y = 1, so (1, 1)

Step-by-step explanation:

Hello! Here is my explanation:

First, you need to set the equations like this:

x + y = 2

2x + 7y = 9

Since you are using elimination, we need to cancel out one variable, either x or y. Let's cancel out x, since that is an easier one to work with since the 2nd equation has a 2 as x's coefficient, whereas there is a 7 as y's coefficient. To cancel out x, we need to multiply the 1st equation by 2, including the "= 2", so that it can be the same as the x in the 2nd equation. Like this:

2(x + y = 2)

2x + 7y = 9

Then, distribute the 2 to the whole equation. Multiply that 2 to the x, the y, and the 2 after that "=" sign, like this:

2x + 2y = 4

2x + 7y = 9

Now we are ready to eliminate! Since we now have the same x and coefficients for both equations, we can cancel them out. To do so, we need to subtract both equations. When we do that, we get 0 as a result for only the x, leaving us with only the y to solve. So we do 2x - 2x (which will be 0, so no need to write that 0), 2y - 7y, and 4 - 9. Like this:

 2x + 2y = 4

- 2x + 7y = 9

-------------------

        -5y = -5

Next, we solve for y by dividing -5 on both sides, which will result in 1 being our y-value:

-5y = -5

-5      -5

y = 1

Now that we have our y-value of 1, we can plug that in for y in either one of our system of equations. It is always best and easiest to use the simplest equation with smaller numbers, so let's use the 1st equation, x + y = 2.

x + y = 2

x + 1 = 2

Now solve for x by subtracting 1 on both sides, which will result in 1 being out x-value:

x + 1 = 2

   - 1   -1

x = 1

So therefore, the solution to this system of equations is (1, 1). We used the method of elimination to solve this system. I hope this helps you understand how to approach these problems! Have a great day :)

The solution for the given system of linear equation is (9/7, 5/7).

The given system of equations are x+y=2 and 2x+7y=9.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Here, x+y=2 -------(I) and 2x+7y=9 -------(II)

Multiply equation (I) by 2, we get

2x+2y=4 -------(III)

Subtract equation (III) from (II), we get

2x+7y-(2x+2y)=9-4

⇒ 7y=5

⇒ y=5/7

Substitute y=5/7 in equation (I), we get

x+5/7=2

⇒ x=2-5/7

⇒ x=9/7

So, solution is (9/7, 5/7)

Therefore, the solution for the given system of linear equation is (9/7, 5/7).

Answer:

c = 35

Step-by-step explanation:

27 = 12c - 5(6 - 2c)

27 = 12c - 30 + 10c

27 + 30 = 12c + 10c

57 = 22c

Answer:

300 days

Step-by-step explanation:

Number of days = k/number of workers

K= number of days × number of workers

K= 600 × 50

= 30,000

Therefore if there are 100 workers then the number of days required for the work can be calculated as follows

30,000= number of days × 100

Number of days = 30,000/100

= 300 days

Answer:

Step-by-step explanation:

The fruit punch has 2.4 gallons but x %

Apple juice has 5.6 gallons but 100 % or 1

The total mixture would then have 8 gallons and 82 %.

2.4+5.6=8

8×0.82 = 6.56

Then you would do 2.4x + 5.6(1) = 6.56

2.4x + 5.6 = 6.56

2.4x = 0.96

0.96/2.4 = 0.4 = 40%

Therefore, Brand A has 40% fruit juice
