Complete the missing value in the solution to the equation.
nikitadnepr [17]

Answer: The answer is x=6, the final set of (x,y) values are (6,-4)

Step-by-step explanation:

You must move around the equation to get it to y= mx+b to find the (x,y) values

Since you know y=-4 since it is stated above, plug in -4 for all y values and solve.

1. 6x+ 7(-4) =4x +4(-4)

2. 6x -28= 4x -16

3. 2x-28=-16

4. 2x=12

5. x=6

Suraj took a slice of pizza from the freezer and put it in the oven. The pizza was heated at a constant rate.
iragen [17]

Answer:

The pizza heats up an average of 7.50 degrees per minute

Step-by-step explanation:

The table shown

Time (minutes) Temperature (degrees Celsius)

1                          2.52

7                          47.547

13                          92.592

Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated

Slope

m   =  (y2 - y1)/(x2 - x1)

Let

(x1,y1) = (7, 47.547)

(x2,y2) = (13, 92.592)

m = (92.592 - 47.547)/(13-7)

m = 7.5075

The pizza heats up an average of 7.50 degrees per minute

Find the value of x that makes m<br> m<br> n<br> (2x + 20)<br> (32°
miv72 [106K]

Answer:  x= 20

Step-by-step explanation:

If m and n are parallel then the  3x and 2x+20 has to have the same measures which means they have to equal each other . So set them equal each other and solve for x.

2x + 20 = 3x

-2x            -2x

 20 = 1x

 x= 20
