You will have to multiply 80 and the percentage. First you will have to change the percentage to a decimal which in this case it will be 0.39 ( for the first one) so then multiply it so it will be 80x0.39=31.2 and you will do the same with the others just replace the numbers with the one that you are doing hope this helps.

Find the values of m and b for this line.

Andrej [43]

Answer:

b=-5, m= - 3/-2

Step-by-step explanation:

Slope equation is y=mx+b. Slope is finding the rise(vertical change) over run(horizontal change). In this case, -3 is our negative rise and 2 is our run. Put that into fraction form, we get negative 3/2. In the slope equation, b represents the y-intercept(where the line touches the y-axis). In this case, it is -5. Hope this helps you!

How to solve 6x + y= -5, -6x + 12y=96 using elimination and does it have no solution or many solutions?

Alika [10]

Answer:

x = -2

Step-by-step explanation:

Arrange 6x + y= -5, -6x + 12y=96 vertically:

6x + y= -5

-6x + 12y=96 Now combine like terms:

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

13y = 91

Solving for y by dividing both sides by 13: y = 7

Find x by substituting 7 for y in the second equation: -6x + 12(7) = 96

Then -6x = -84 + 96, or:

-6x = 12, and so x = -2
