What are m and b in the linear equation y=30x + 20​
UkoKoshka [18]

Answer:

m = 30, b = 20

Step-by-step explanation:

1. The equation is written in slope-intercept form, so it follows the following equation: y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. As you can see, 30 is the value that took the place of m, and 20 is the value that took the place of b.

Therefore, m is 30 and b is 20.

7x+3+6x+11 can u give a example of how to solve it
yKpoI14uk [10]

Combine like terms.

Since 7x and 6x both have a variable of x, you can combine them.

7x + 6x = 13x

After that, you are left with:

13x + 11 + 3

You also have two numbers without variables; 11 and 3. You can also combine those.

11 + 3 = 14

So, your final answer would be:

13x + 14
