how many solutions does 6(x + 2) = 5(x + 7) have
-3(1 + 6r) = 14-r
Solve for r
Answer:
1
Step-by-step explanation:
-3(1+6r)=14-r
use distributive property
-3(1)+(-3)(6r)=14-r
-3+18r=14-r
r+18r=14+3
19r=17
divide both sides by 19

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

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.
An apartment building has a parking lot with 12 parking spaces for tenants. At 6 a.m., all 12 spaces were full. At 8 a.m., the number of cars in the lot had decreased by 4. By 9 a.m., there were no cars left in the lot. Use the number line to show each change in the number of cars in the parking lot. What integer represents the change in the number of cars between 8 a.m. and 9 a.m.?

RS bisects TU at Q. If TQ=5k-9 and QU=15-x
Answer:
x = 4, TU = 22
Step-by-step explanation:
Given that TS bisects TU at Q , then
TQ = QU , substitute values
5x - 9 = 15 - x ( add x to both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Thus
TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22
Raj is deciding between two cell phone plans, A and B, which are both linear functions. The monthly charge for plan A according to the number of minutes used is shown in the table. Monthly Charge for Plan A Minutes used, x Monthly charge ($), y 0 14.45 3 14.84 6 15.23 9 15.62 12 16.01 Plan B has the same monthly base charge as plan A, but it charges a different amount per minute used. If the total monthly charge for plan B is $22.10 when 45 minutes are used, what is the slope of the linear function that represents the cost of plan B?
Answer:
B
Step-by-step explanation:
The slope of the linear function for plan B is of $0.17.
---------------------------
A linear function has an equation in the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, measuring how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.---------------------------
Plan B has the same monthly base charge as plan A, that is, from the table, when [tex]x = 0, y = 14.45[/tex], and thus, (0, 14.45) is one of the points of the function.The monthly charge for 45 minutes is of $22.10, thus, another point is (45, 22.10).Given two points, the slope is given by the change in y divided by the change in x. Thus:[tex]m = \frac{22.1 - 14.45}{45 - 0} = 0.17[/tex]
The slope is of $0.17.

Given f(x) = | – 5 – 4x| ,find the following:
f(- 10) =
f(-11) =
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]
