The value for b in y=mx+b,directly from the table w/out drawing a graph or going any calculations ?

Answers

Answer 1

Answer: the value of b is the y intercept or when the line crosses the y axis
this only happens when the value of x=0
so just look for the ordered pair in the table with x=0 and y=b
so if you had a table and saw
(0,3)
(x,y)
so the point where x=0 is at point (0,3) y=3
therefor b=3

basically look for the matching y value for when x=0

Answer 2

Answer: The b value in y=mx+b is how many units up or down the y-axis you go from the origin. For example, if y=mx+2, you would move 2 units up, or if it was y=mx-3 you would move 3 units down.

If you want to watch a 2 hour movie that starts at 4PM and you want to watch a 3 hour movie that starts at 2PM,there is a schedule conflict.

A: True

B : False

Answers

True.

A 3 hour movie that starts at 2PM would end at 5PM (2 + 3 = 5) which is an hour past the 4PM time.

true, if you start the three hour movie at 2pm then you will be done with that one at five, while the other one starts at four so you would miss an hour of it

What is the measure of angle x?

Answers

Answer:

x = 47°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for x

x = 180° - (31 + 102)° = 180° - 133° = 47°

Answer:

Step-by-step explanation:

180-(102+31) (asp)

=180-133

=47

A backpack that normally sells for $39 is on sale for 33% off. Find the amount of the discount and the sale price.

Answers

1. 33% = 0.33
$39 x 0.33 = $12.87
$39 - $12.87 = $26.13

Discount: $12.87
Sale price: $26.13

First find 10%
10% of $39 = $3.90
so...
30% of $39 = $11.70
This is because 30% is 10% multiplied by 3. So you just have to multiply 3.90 by 3.
Then you would work out 1%
1% of $39 = $0.39
so...
3% of $39 = $1.17
This follows the same principle as before.
Now you have to add them together to get the discount price.
11.70 + 1.17 = $12.87

To get the price after the discount, simply take the discount price away from the usual price:
39 - 12.87 = $26.13

Therefore the two answers to your questions are..
$12.87
and..
$26.13
Hope this helped :)
