Answer: 7m - 40

Step-by-step explanation:

Monday = m

Tuesday = m + 15

Wednesday = m + 15 + 30 = m + 45

Thursday = 2 × m = 2m

Friday = 2m - 20

The expression will now be:

= m + m + 15 + m + 45 + 2m + 2m - 20

= 7m- 40

The lines a and b intersect at point C.<br><br> What is the value of y?
Amanda [17]

Using the definition of vertical angles, the value of z is: 15.

<h3>Vertical Angles Pair</h3>

The two pairs of opposite angles formed when two straight lines intersect are called vertical angles, and are therefore congruent to each other.

Thus:

2z + 10 = 40

2z = 40 - 10

2z = 30

z = 30/2

z = 15

Therefore, using the definition of vertical angles, the value of z is: 15.

HELP PLEASE!
Citrus2011 [14]
A table can be used to find the rate of change by giving you a visual representation of how the operation changes over time for example in the link i'm about to post you can see how much more money is earned as more cars are washed, it is showing how much money is being made OVER TIME, hope this helps :)

now to answer your second question, say you would like to know how many miles Tracy ran over a course of 2 hours, the x axis would be the miles and the y axis would be the time, then you would plot the different points on the graph showing the rate at which she is running
'
to answer your last question a linear interval would be a sequence of numbers that when places on a number line they will form a line, a nonlinear interval is a sequence of numbers that don't make a line because there are inequities meaning the numbers in the sequence are all over the place 

Hope this helps and i will post the pictures so you can have a visual representaion

20×^2-30x-40 solve for x
Oduvanchick [21]

Answer:

x = 12

Step-by-step explanation:

Solve for x:

360 - 30 x = 0

Subtract 360 from both sides:

(360 - 360) - 30 x = -360

360 - 360 = 0:

-30 x = -360

Divide both sides of -30 x = -360 by -30:

(-30 x)/(-30) = (-360)/(-30)

(-30)/(-30) = 1:

x = (-360)/(-30)

The gcd of 360 and -30 is 30, so (-360)/(-30) = (-(30×12))/(30 (-1)) = 30/30×(-12)/(-1) = (-12)/(-1):

x = (-12)/(-1)

(-12)/(-1) = (-1)/(-1)×12 = 12:

Answer:  x = 12
