Answer:
see attached
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.

Ben can type 2/5 of a page of an essay in 1/2 minute. How much time would
take him to type one full page of the essay?
Answers
Answer:
ok so first i want to figure out what 2/5 converted to percent is......
you can find it out on a calculator or on paper by dividing 2 / 5 = 0.4
so this is 40% and if it takes him half a minute to do this, it takes him about 30 seconds to finish 40% of the essay and there is a full 60% still waiting to be done, so lets see,
40% + 40% = 80%
so that is about 1 full minute to write 80% we are still left with 20% so let's see how much time does it take to write 20% of the essay, in 40% it takes 30 seconds and in 80% it takes 60 seconds. So since 20% is half of 40% then we must divide the time in half so 30 / 2 = 15
So if we add all these numbers up it equals 1:15 minutes to write an essay
I hope this helps and please mark brainliest if i got it right!
The time taken by Ben to write a full page will be 1:15 minutes.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Answer:
x=8, y=73/3
Step-by-step explanation:
they ask to solve by substitution so from second equation find y
4x-3y= -41 isolate y
4x+41 = 3y divide both sides by 3
(4x+41)/3= y substitute this y in the first equation
5x+2y = -34
5x+2(4x+41)/3 = -34 distribute and find the common denominator
3*5x+(8x+82)/3 = -34
15x+8x+82=-34*3 cross multiply
23x = -102-82
x=-184/23=8
y=(4*8+41)/3=73/3 is about 24.333..
You are running an experiment in class where you draw colored marbles out of a bag. There are
eight marbles in the bag, you will draw five times, and you will replace the marble each time. How many ways can you draw the marbles out of the bag?
A: 40
B: 3,360
C: 4,096
D: 32,768
Answers
Answer:
32768 ways
Step-by-step explanation:
Given
Marbles = 8 marbles
Selection = 5 (with replacement)
Required
Determine the number of ways
Because it is a selection with replacement; each selection is as follows:
[tex]First = 8\ marbles[/tex]
[tex]Second = 8\ marbles[/tex]
[tex]Third= 8\ marbles[/tex]
[tex]Fourth = 8\ marbles[/tex]
[tex]Fifth = 8\ marbles[/tex]
Total number of ways is then calculated as:
[tex]Total = 8 * 8 * 8 * 8 * 8[/tex]
[tex]Total = 32768[/tex]
