1/9 (2m - 16) = 1/3 (2m + 4)
Please follow the steps in the picture!
Answer:
1/9 (2m - 16) = 1/3 (2m + 4)
expand
2/9m- 16/9 =2/3m +4/3
move m to other side
- 16/9 =2/3m (-2/9m) +4/3
simplify
- 16/9 =(6-2)/9m +4/3
- 16/9 =4/9m +4/3
move 4/3 to other side
- 16/9 -4/3 =4/9m
- 16/9 -12/9 =4/9m
-28/9 = 4/9m
multiply by 9
4m= -28
m= -7
Erica has $12 credit on her Cel-Tel phone card. It costs her $1 to make a phone call using her Cel-Tel card. Erica also has $15 credit on her MTT phone card. It costs her $2 to make a phone call using her MTT card. Which system of equations can be solved to find the number of calls, x, that Erica can make and have the same amount of money, y, on both phone cards?
yy==−2x+15−x+12
y = - 2 x + 15 y = - x + 12
yy==2x+15−x+15
y = 2 x + 15 y = - x + 15
yy==−2x−15−x−12
y = - 2 x - 15 y = - x - 12
yy==15x−212x−1
y = 15 x - 2 y = 12 x - 1

f(1)=−6

f(n)=f(n−2)+f(n−1)
f(3)=f(3)=f, left parenthesis, 3, right parenthesis, equals
HURRY!!!!
the value of function at n = 3 is f( 3 ) is - 10.
To find the value of f( 3 ), we can use the given recursive formula:
f(n) = f( n - 2 ) + f( n - 1 )
We already have the values of f(1) and f(2):
f(1) = - 6
f(2) = - 4
Now, let's apply the recursive formula to find f(3):
f(3) = f( 3 - 2 ) + f( 3 - 1 )
f(3) = f(1) + f(2)
f(3) = - 6 + (- 4)
f(3) = - 10
So, the value of f(3) is - 10.

Answer:
-9 degrees
Step-by-step explanation:
-14 + 8 = -6
-6 + 2 = -4

The temperature at 6pm dropped down to 5°.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that at 6am one morning the temperature was -14 degrees by noon it rose 8 degrees and then rose another 2 degrees by 3pm. By 6pm the temperature had dropped 5 degrees
We can write -
T{6 AM} = - 14°
T{12 PM} = 8°
T{3 PM} = (8 + 2)° = 10°
T{6 PM} = 10° - 5° = 5°
Therefore, the temperature at 6pm dropped down to 5°.

4. Which situation best demonstrates the phrase "correlation is not causation"?
A. As rainfall increases, so does the water level in the river.
B. The hotter the temperature, the faster ice will melt.
C. As the number of people with vision loss increases, the sale of hearing aids increases.
D. The fewer mistakes a student makes on a math test, the better their grade is on the math test.
a
Answer:
C
Step-by-step explanation:
We can solve this by analyzing if the event causes the result. If it does not, then there is correlation but not necessarily causation
A. Event: Rainfall. Result: Water level rises
Does rainfall cause an increase in water level? Yes, so this is incorrect
B. Event: Temperature increase. Result: Ice melting
Does an increase in temperature cause ice to melt faster? Yes, so this is incorrect
C. Event: More people have vision loss. Result: Hearing aids sales increase
Does more people having vision loss cause hearing aids sales to increase? No, vision loss does not cause a need for hearing aids -- hearing loss would, but vision loss does not. This is correct
D. Event: A student makes fewer mistakes. Result: A better grade
Do fewer mistakes cause better grades? Yes, so this is incorrect

The sum of 6 consecutive integers is 387. What is the sixth number in this sequence.
Answer:
67!
Step-by-step explanation:
A way to look at it is, since the number is 387, it can be broken into 6 parts. 50x6 is about 300. That leaves 87 to be left over. So it's safe to assume each number will be around 50-60, so I started to add up six consecutive numbers together until I reached my final set of numbers to reach 387.
My numbers were 62+63+64+65+66+67=387
I hope this makes sense!

Question:
Below is a graph of 2 lines. Match the line with its slope.
Answer:
l: 1
k: 2
Step-by-step explanation:
The slope of a line is "the amount it goes up divided by the amount it goes right".
So if you pick a point on the line, and then step one grid position to the right, how much does it go up (or down, then you have a negative slope)?
In line l, it goes up one grid position for every step to the right, hence the slope is 1.
In line k, it goes up two positions for every step to the right, hence the slope there is 2.
Hope this explains it.

Translate. Eight less than the difference of a number and five is twelve.
Answer:
(x - 5) - 8 = 12
Step-by-step explanation:
Lets portion each part out:
Eight less than
The difference of a number and five
Is twelve.
First, we must write down the portion with "a number" in it: x - 5. We use subtraction because the sentence states "the difference".
Next, we will write down "eight less than". The problem states that twelve is "eight less than" the difference. This means that we must subtract 8 from out first part: (x - 5) - 8
Finally, the sentence tells us that this equals twelve: (x - 5) - 8 = 12

4x-y=10 and y=2x-2 answers
Answer:
y = 6
x = 4
How to find 'x':
4x - y = 10
y = 2x - 2
First, you need to substitute the 'y' into the first equation.
4x - 2x - 2 = 10
Next, add the x's together. As it's a negative 2x then take away 2 from 4.
2x - 2 = 10
3. Now that it's a normal equation, you can add 2 to cancel out the -2
2x = 8
4. Then divide the 8 by 2 and you will get the answer to x which is 4
x = 4
How to find 'y':
1. Now that we have found out 'x'. Let's go back to y = 2x -2 and use the x to found the answer out. It should be something like this:
y = 2x - 2
y = 2(4) - 2
y = 8 - 2
8 - 2 = 6
y = 6
Conclusion:
So the answer would be:
y = 6
x = 4
You can see if it's correct by putting y into 4x - y = 10.:
4x - 2 = 10
4(4) - 6 = 10
16 - 6 = 10
So that means that y and x are the correct answer.
