an = 8 + (n - 1) × 4
an = 8 + 4n - 4
an = 4n + 4
Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
The nth term (explicit formula) of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 12 - 8 = 4 , then
[tex]a_{n}[/tex] = 8 +4(n - 1) = 8 + 4n - 4 = 4n + 4

100 PTS!!!! The perimeter of a rectangle is 4(4x - 5) inches. the length of the sides of the rectangle are 2 x + 3 inches and 3x + 2 inches. WRITE AND SOLVE an EQUATION to find the length of each side of the rectangle. ( you have to show all work for branliest!!!!! :D)
Answer:
2 sides are [tex]\frac{33}{13}[/tex] or 2.5
2 sides are [tex]\frac{47}{13}[/tex] or 3.6
Step-by-step explanation:
There must be 2 2x+3s and 2 3x+2s
The perimeter is the sum of the sides (it has 4 sides)
2(2x+3) + 2(3x+2) = 4(4x-5)
distributive property
2*2x + 2*3
4x+6
other one
2*3x + 2*2
6x+4
perimeter
4*4x + 4*-5
16x-20
together...
(4x+6) + (6x+4) = 16x-20
add like terms
10x+10 = 16x-20
add 20 to both sides
10x+30 = 16x
subtract 10x from both sides
30 = 26x
divide by 26 on both sides
[tex]\frac{30}{26} = x[/tex]
simplify
[tex]\frac{15}{13}[/tex]
Substitute the x value
2 of the sides are 2x+3
so
[tex]2(\frac{15}{13} ) + 3[/tex]
[tex]\frac{30}{13} + \frac{3}{1}[/tex]
[tex]\frac{33}{13}[/tex]
or 2.5
other sides
[tex]3(\frac{15}{13} ) + 2[/tex]
[tex]\frac{45}{13} + \frac{2}{1}[/tex]
[tex]\frac{47}{13}[/tex] or 3.6
That's all I can say for now! Hope this helps and a thank won't hurt! :)
Solve for x (and y if necessary) and explain your reasoning
Answer:
x = -7
Step-by-step explanation:
These angles are supplementary because they're same side interior angles. Supplementary means the 2 angles add up to 180
Equation:
x + 67 + x + 127 = 180
2x + 194 = 180
2x = 180 - 194
2x = -14
x = -14/2
x = -7
Hi how u doin ?
[tex](x + 67) + (x + 127) = 180[/tex]
[tex]x + x + 67 + 127 = 180[/tex]
[tex]2x + 194 = 180[/tex]
Subtract both sides 194
[tex]2x + 194 - 194 = 180 - 194[/tex]
[tex]2x = - 14[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{ - 14}{2} \\ [/tex]
[tex]x = - 7[/tex]

52,300,000 in scientific rotation
Answer:
-5.230,0000
Step-by-step explanation:
Your number in decimal form is -52,300,000 . The negative sign remains unchanged. To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, -52,300,000 becomes -5.230,0000
Function g gives the amount of a chemical in a persons body in milligrams t hours since the pain ent took the drug. The equation g(t)=600•(3/5)t.
a. What does the fraction (3/5) mean?
B. What are the domain and range of g?
C. Sketch a graph of g
The fraction 3/5 means that every hour, the amount of chemical increase by a factor of 3/5.
The domain of the function is (0, ∞) and the range is (600, ∞)
What is an exponential function?
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let g represent the amount of a chemical in a persons body in milligrams t hours since the patient took the drug.
[tex]g(t) = 600(\frac{3}{5} )^t[/tex]
The fraction 3/5 means that every hour, the amount of chemical increase by a factor of 3/5.
The domain of the function is (0, ∞) and the range is (0, 600)

To avoid a storm, a passenger-jet pilot descended 0.68 mile in 0.8 minute. What was the plane's average change of altitude per minute?
Answer:
0.85 m
Step-by-step explanation:
0.68/8=A decent of 0.085 miles per 0.1 minute
So per minute 0.085x10 =0.85, our plane will have a change of 0.85 m in altitude

Answer:
A - 142
B - 38
C - 38
D - 142
E - 142
F - 38
G - 38
H - 142
Step-by-step explanation:
It's been a while since I've done these so please don't judge
Answer:
Well this is pretty simple
Parralel lines cut by a transversal.
So we have one measurement of 142 which is a
A and B are supplementary (When added up you get 180 degrees)
So basically to find that you can do this
180-142=38
So B is 38
We can now use vertical angles.
A and D are vertical and vertical angles are congruent (equal)
d is 142
B and c are congruent
B is 38 so C is also 38
Now We find EGHF
Techcinally we can just do what i would do which is draw and x between the vertical angles
So if drawn an ”X” you can see the sam exact pattern as for ABCD
Which in this case E is 142
H is 142
F is 38
G is 38
If done the hard way you can use altenrate/same side (interior exterior)/ Corresponing angles.
So Here’s what you need to know
Alternate interior and exterior are equal
Correspnding angles are equal
Same side are supplementary
Thats all you need to know.
Interior is basically BD and EG
Exterior is AC and FH
Correspnding are basically same sides but one is ont he inside and one is on the outside
Ex:
A and E
B and F
C and G
D and H
Same side is EXACLTY what is sounds like, the same side but everything has to be either interior or exterior
(Interior) B and E
(Interior) D and G
(Exterior) A and F
(Exteiror) C and H
Final answers:
A- 142
B- 38
C- 38
D- 142
E- 142
F- 38
G- 38
H- 142
Find the distance between the points (8.5,8.9) and (8.5,2.2).
Answer:
Distance = 6.7 units
Step-by-step explanation:
Distance formula: [tex]d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]d = \sqrt{(8.5-8.5)^{2}+(2.2-8.9)^{2}} = \sqrt{(-6.7)^{2}} = 6.7[/tex]
Note that distance is always positive

Using the digits 1 to 9 at most one time each fill in the boxes to create an equation that has a negative solution
[]x+[]=[]x+[]
Answer:
[4]x+[8]=[1×]+2
Step-by-step explanation:
x will be negative now that the more x you have the higher your number will have to be.
The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
One possible solution is,
[1]x + [2] = [3]x + [9]
To see that this equation has a negative solution, we can rearrange it to get:
x + 2 = 3x + 9
x - 3x = 9 - 2
-2x = 7
x = -3.5
Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.

7x + 2y = –1
7x + 2y = 1
14x + 4y = –1
14x + 4y = 1
Answer:
7x + 2y = 1
Step-by-step explanation:
1. Find the slope of the line.
(y2-y1)/(x2-x1) ----> (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4
*lets simplify into (7/-2)*
2. Write into slope intercept form.
y=mx+b (m is the slope) (b is the y intercept)
y = (7/-2)x + b
We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.
11 = (7/-2)(-3) + b
11 = 10.5 + b
b = 0.5 or 1/2
slope intercept form y = (7/-2)x + 1/2
Now we convert to standard form: ax+by=c
*In this form we our a term cannot be a fraction nor can it be negative*
1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.
(7/2)x + y = 1/2
2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.
2(7/2)x + 2y = 2(1/2)
Simplify and you get
7x + 2y = 1

Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

but for station A it is unclear on the graph
a way to work it out is that you know that 10= 1.00 so 12 = 1.2
( divide 12 by 10 )
station B = discount for 12 gallons = 0.6
but Station A = discount for 12 gallons = 1.2
