Step-by-step explanation:
Hey there!!
Just simply work with it.
We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.
So, just do accordingly.
The point is (2,-6) and slope is -1.
[tex](y - y1) = m(x - x1)[/tex]
Where, "m" is a slope.
Put all values.
[tex](y + 6) = - 1(x - 2)[/tex]
Simplify them to get answer.
[tex](y + 6) = - x + 2[/tex]
[tex]y = - x - 4[/tex]
Therefore the equation is y= -x-4 OR can be written as x+y+4=0.

Neal and Catherine recently graduated from college and are starting a family. Currently, they are just making ends meet with their $45,000 salary. They want to contribute the maximum amount (currently $2,000) to fully fund an Educational Savings Account when their baby is born. How much additional money will they need to budget every month and what are some things they can do to their budget to find the money? Please it's my last question and I have a lot of other work I'm doing right now.
Answer:
Not enough data is provided but I will try my best.
Step-by-step explanation:
If the couple is desiring to save money for their baby's education then and they can opt to following options:
I think they must first lower their fixed expenses which includes their rental expenses per year, branded clothing cost per year, use of luxury items, etc. This will help them save more than what they are desiring to plan for their baby's future. This will help them own a small house which will substantially lower their expenses because rentals are usually 10-20% of household Income. Luxury expenses can be lowered if the by 80% by simply opting local brands. Furthermore, if they use bicycle then the cost of traveling which is 4-10% can also be significantly lowered. Modern research shows that owning a car is expensive than using Uber a year. I think using local transport will be very beneficial. Eating quality products is recommended but they must be cooked at home because the street food is very expensive and increases the cost of living. All these measures will help them in buying a house that will help them keep their expenses under control. Average saving by using these measures would be $25k which means they can own a house costing them $100-150k within 4 to 6 years.
I recommend them funding Educational Savings Account when their baby is studying in 3rd standard because public high school education is free for all the US residents. The University degrees that are the most expensive in the world cost around $230-$331k which means that if the couple starts saving $2000 a month, 10 years before the child enters the university then according to Florida 529 planning, after deducting for college studies they can save up to $272k which is more than enough.
Furthermore the amount deposited in the account is tax deductible and have to be paid aggregated when the money is withdrawn. So it also has a tax advantage.
-140 = -2(8r + 6) sorry prob just a few more questions i think
Answer:

Step-by-step explanation:
so first distribute -2
so you get -140=-16r-12 then add 12 to both sides to get -16r by itself
so you have -128=-16r divide both sides by -16
the - cancel each other out so you get 8=r

f(12) =
f(2)=
Answer:
[tex]f(10) = 35 \\ \\ f( - 11) = 39 \\ \\ f(12) = 53 \\ \\ f(2) = 13[/tex]
Step-by-step explanation:
[tex] f(x) = | - 5 - 4x| [/tex]
To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x
NB: Absolute value of a negative number is the same number but positive.
So we have
[tex]f( - 10) = | - 5 - 4( - 10)| \\ = | - 5 + 40| = 35 \\ \\ f( - 11) = | - 5 - 4( - 11)| \\ = | - 5 + 44| = 39 \\ \\ f(12) = | - 5 - 4(12)| \\ = | - 5 - 48| \\ = | - 53| = 53 \\ \\ f(2) = | - 5 - 4(2)| \\ = | - 5 - 8| = | - 13| \\ = 13[/tex]

What type of number is 3\pi+13π+1
Answer: Irrational
Step-by-step explanation:
At a pet store, the lizards in aquarium A have a mean length of 13 cm and a range from 9 cm to 15 cm. In aquarium B. the
lizards have a mean length of 15 cm and a range from 14 cm to 17 cm. Which statement BEST compares the lizards in the
two aquariums?
A:
A)
On average, the lizards in aquarium A are longer.
B)
Aquarium A has the longest lizard at this pet store.
C)
The lizards in aquarium A vary in length more than aquarium B.
D)
The lizards in aquarium B vary in length more than aquarium A.
Answer:
C
Step-by-step explanation:
We can go through the answers and use the process of elimination.
For A, it says that lizards in A are longer. We can look at the numbers for A compared to B and see that B has longer lizards so we know that A is wrong.
For B, it says that aquarium A has the longest lizard. As we just found out, B has longer lizards so this option would be wrong as well.
Next, we can look at C, which says that lizards in A vary in length more than in aquarium B. We can check this by looking at the range for each aquarium. In A, we see that they have lengths from 9 to 15. 6 cm would be the difference. In aquarium B, we see 14 to 17. 3 would be the difference. 6 is higher than 3 so we know that aquarium A's lizards vary more than aquarium B.
In option D, we can see that this just tells us the opposite of what we just learned in C, so we know it is wrong.
Hope this helps!!
The lizards in aquarium A vary in length more than in aquarium B.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, At a pet store, the lizards in aquarium A have a mean length of 13 cm and a range from 9 cm to 15 cm. In aquarium B. the lizards have a mean length of 15 cm and a range from 14 cm to 17 cm.
On average, the Length of Lizards in Aquarium B is greater than the Length of Lizards in Aquarium A.
Since the range Of length of lizards in Aquarium B is 14 to 17 cm which is bigger than the range of A, aquarium B has the longest lizard at this pet store.
Since,
the range is the area of variation between upper and lower limits on a particular scale.
Thus, In aquarium A, the lizards' lengths range more widely than in aquarium B.

If 2x + y = 10, and 3x - y = 0, then y = ?
Answer:
y = 6
Step-by-step explanation:
2x + y = 10, and 3x - y = 0
We will use elimination
2x + y = 10
3x - y = 0
-----------------------
5x +0y = 10
5x = 10
Divide by 5
5x/5 = 10/5
x =2
3x - y = 0
3*2 -y = 0
6-y =0
Add y to each side
6 = y
