(a) Solve the system of linear equations:
x + y = 14
X-y=6
Answers
Answer:
x=10,y =4
Step-by-step explanation:
x + y = 14
X-y=6
Add the two equations together to eliminate y
x + y = 14
X-y=6
-----------------------
2x +0y = 20
Divide by 2
2x/2 =20/2
x = 10
Then find y
x+y = 14
10+y =14
Subtract 10 from each side
10+y-10=14-10
y =4
Answer:
x = 10, y = 4
Step-by-step explanation:
One way of doing this is by doing the substitution method
To do this you first need to put x on one side (x = y + 6)
Now where there is an x in the first equation you put that instead
(y + 6) + y = 14
After this, you solve for y (y = 4)
Lastly, you put the 4 where there is a y and then solve for x
x - 4 = 6
x = 10

Which is
6(104) = 624
Hope this helps you
Answer:
6(104) = 624
Step-by-step explanation:
The summation symbol ...
[tex]\sum\limits_{n=1}^{104}{\text{expression}}[/tex]
means that the expression is evaluated for n=1, n=2, n=3, n=4, ... up to n=104 and all of those are added together. Here, the expression being evaluated is "6", which does not depend on n. So, this is simply the sum of 104 instances of 6:
6 +6 +6 +6 ...+6 . . . . 104 terms in the sum
As we know, repeated addition can be accomplished by multiplication:
= 6(104) = 624

(3 points) Part C: Chickens can only be raised in the area defined by y > −4x + 3. Explain how you can identify farms in which chickens can be raised. (2 points)
Answers
Answer:
Hope this helps
Step-by-step explanation:
For part A, we want two inequalities that have F and D as solutions, but none of the other points. The easiest way to do this is construct two lines that pass through the origin, and then figure out which way the inequalities need to face based on the points we want to include. Our lines will be:
The first line intersects F and the second line intersects D, so we need to figure out which way to point the inequalities so both include the point they do not intersect:
So our system is:
Part B: To verify, plug in the x and y values for D and F and verify that it creates true statements in the system.
Part C: You can plug in the different x, y values for the points. The points which create true statements identify farms where chickens can be raised, while those which create false statements cannot raise chickens.
Which best describes the relationship between the lines with equations -36x + 8y = 16
and -9x + 2y = 4?
Answers
Answer:
Infinitely many solutions.
Step-by-step explanation:
-36x + 8y = 16
-9x + 2y = 4
4(-9x + 2y = 4)
-36x + 8y = 16
Now, we can see that the two lines are exactly the same, which means that they have infinitely many solutions.

in a survey of 420 people, 85% said they drink coffee. of these, 1/3 said they drink their coffee black. how many of the people surveyed drink it black?
Answers
Answer:
A.) 119
420 * 0.85 is 357 and 357 * 1/3 is 119
Hope this helps ^^
Answer:
119
Step-by-step explanation:
The total number of people who had taken the survey is 420 wich is equivalent to 100%.
The percentage of people who drink coffee is 85%.
●●●●●●●●●●●●●●●●●●●●●●●●
Let x be the number of people drinking coffee
● 420 => 100%
● x => 85%
These values are proportional so we can cross-multiply them
● x*100 = 420*85
● x = (420*85)÷100
● x = 357
The number of people who drink coffee is 357.
■■■■■■■■■■■■■■■■■■■■■■■■■
Let y be the number of people who drink black coffee.
y is 1/3 of 357 since people who drink black coffee represent the third of the total number of people drinking coffee in general.
● To get y multiply 1/3 by the total number of people drinking coffee (357)
●y = (1/3)*357
● y = 119
119 is the number of people who drink black coffee

A certain worker makes $12 per hour for the first 40 hours and $18 for every hour more than 40. Compute her pay for working 45 hours.
Answers
Answer: $570
Step-by-step explanation:
She worked 5 hours more than 40. Thus, for her extra hours she made 18*5, or $90. For her other 40, she made 40*12, or $480. Thus, she made 480+90 dollars, or $570.
Hope it helps <3
Answer:
$570
Step-by-step explanation:
Since she is working 40 hours you need to multiply 12 · 40 first and should get 480
Since there is an extra 5 hours you need to do 18 · 5 = 90
Lastly, you add 480 and 90 and you will get 570

Statement 2: If the sprinklers are on, then the grass is wet.
Answers
Answer:
1. Both forward and backward
2. Only forward
Step-by-step explanation:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.

This is only broken up into two main parts: the "a" and the "b" of the equation.The "a" is the y-coordinate when x is at 0 and the y-coordinate is 8 there so that fills it in.The "b" is the rate at which for every time x increases by 1, the y decreases by a portion of its current. In this case, every time the x increases by one, the y value cuts in half which means the rate is .5 or one half.Therefore, the answer is 8(.5)^xMei-Ling is one of 6 members of a committee.
