8 times of the eight term of an arithmetic progression is equal to 12 times of the twelfth term. find its first term if the common difference is -2 .
Answer:
a₁ = 38
Step-by-step explanation:
Given AP, where:
8a₈ = 12a₁₂d = -2,a₁ = ?=============
Solutionaₙ = a₁ + (n-1)d
a₈ = a₁ + 7d = a₁ + 7*(-2) = a₁ - 14a₁₂ = a₁ + 11d = a₁ + 11*(-2) = a₁ - 228a₈ = 12a₁₂
8(a₁ - 14) = 12(a₁ - 22)2(a₁ - 14) = 3(a₁ - 22)2a₁ - 28 = 3a₁ - 663a₁ - 2a₁ = -28 + 66a₁ = 38A family is comparing different car seats. One car seat is designed for a child up to and including 26 lb.

Given 2^m + 2^m = 2^n, express m in terms of n.
Answer:
m = n-1
Step-by-step explanation:
2^m + 2^m = 2^n
Add on the left
2( 2^m) = 2 ^ n
2^1 ( 2^m) = 2^n
We know that a^b* a^c = a^ (b+c)
2^(1+m) = 2^n
The bases are the same so the exponents are the same
1+m = n
Solving for m
1+m-1 = n-1
m = n-1
Given :
2^m + 2^m = 2ⁿ
→ 2(2^m) = 2ⁿ
→ 2¹ × 2^m = 2ⁿ
→ 2^(1 + m) = 2ⁿ
As bases are equal, exponents are equal too.
→ 1 + m = n
→ m = n - 1

Answer: see proof below
Step-by-step explanation:
Use the Sum/Difference Identity: tan (A + B) = (tanA + tanB)/(*1 - tanA · tanB)
Scratchwork:
tan (50) = tan (40 + 10)
[tex]= \dfrac{\tan 40+\tan 10}{1-\tan 40\cdot \tan 10}[/tex]
tan 50 (1 - tan 40 · tan 10) = tan 40 + tan 10
tan 50 - tan 50 · tan 40 · tan 10 = tan 40 + tan 10
tan 50 = tan 40 + tan 10 + tan 50 · tan 40 · tan 10
Use the Reciprocal Identity: cot A = 1/ tan --> cot A · tan A = 1
Proof LHS → RHS
LHS: tan 50 - tan 40
Substitute tan 50: tan 40 + tan 10 + (tan 50 · tan 40) · tan 10 - tan 40
Simplify: tan 10 + (tan 50 · tan 40) · tan 10
Reciprocal Identity: tan 10 + tan 10
Simplify: 2 tan 10
LHS = RHS: 2 tan 10 = 2 tan 10 [tex]\checkmark[/tex]

El Sr negron tiene que redactar una serie de cartas en su oficina. A Lourdes le toma 6 horas pasar todas las cartas. A su compañera rosabel, le toma 9 horas en realizar la misma tarea. Si ambas trabajan juntas para hacer todo el trabajo d ela oficina,
a. Cuánto tiempo le tomará a ambas realizar el trabajo?
Answer:
3.6 horas
Step-by-step explanation:
Sea el número total de horas que ambos trabajaron = T
Deje que la cantidad total de letras por las que pasaron = 1
De la pregunta, se nos dice:
Lourdes necesitó 6 horas para revisar las cartas.
Esto significa que, cada 1 hora, Lourdes revisaba 1/6 de las letras
Rosabel tardó 9 horas en leer las letras.
Esto significa que, cada 1 hora, Rosabel revisó 1/9 de las letras
Por lo tanto,
(1/6 × 1) T + (1/9 × 1) T = 1
(1/6 + 1/9) T = 1
(3 + 2/18) T = 1
(18/5) T = 1
5T / 18 = 1
Cruz multiplicar
5T = 18
T = 18/5
T = 3.6 horas
Por lo tanto, les tomó a ambas 3.6 horas hacer el trabajo.

Find the equation of a parabola with a focus at (-4, 7) and a directrix of y=1. ANSWERS ATTACHED, 15 points, due in 2 HOURS!
Answer:
Solution: y - 4 = 1 / 12(x + 4)² or Option B
Step-by-step explanation:
Since the directrix is vertical, use the equation of a parabola that opens up or down -
(x - h)² = 4p(y - k)
Remember that the vertex, (h, k) is halfway between the directrix and focus. Therefore we can find the y coordinate of the vertex using the formula y = y coordinate of focus + directrix / 2.The x -coordinate will be the same as the x coordinate of the focus.
Vertex: (- 4, 7 + 1 / 2) = (- 4,4)
Now we can find the distance from the focus to the vertex. The distance from the vertex to the directrix is represented by | p |. We can subtract the y coordinate of the vertex from the y -coordinate of the focus to find p.
p = 7 - 4 = 3
Substitute the known values for these variables into the given equation (x - h)² = 4p(y - k) to get our solution.
(x + 4)² = 4(3)(y - 4),
(x + 4)² = 12(y - 4)
1 / 12(x + 4)² = y - 4
y - 4 = 1 / 12(x + 4)² ~ As you can see your solution is option b.

6|2x+3|=36 need a mini step by step
Answer:
x=1.5
Step-by-step explanation:
We are trying to get x by itself to see what it equals.
6(2x+3)=36
So first you want to distribute you proprieties. You do that by multiplying 6 and 2x. Then multiplying 6 and 3.
12x+18=36
Now in equations where you need to find the variable, whatever you do on one side of the equal sign, you have to do on the other side. So now we want to subtract 18 from both sides.
12x+18=36
-18 -18
Then we divide 12 from both sides.
12x=18
÷12 ÷12
Now you have your answer!
x=1.5
What is the slope of the line that passes through (4, 5) and (8, -1)?
Answer:
m = -3/2
Step-by-step explanation:
The slope of a line is equivalent to the formula:
m = slope = rise/run = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Given the two coordinate pairs, we can label them accordingly.
In math, coordinate pairs are set up in a way that the x-coordinate is given first and the y-coordinate is given second.
Therefore, with this information, we can label the coordinate pairs with this info.
[tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is the default labeling system for two coordinate pairs.
Then, we can use this information to label our coordinate pairs, place them into the slope formula, and solve for m.
[tex]m=\frac{-1-5}{8-4}\\\\m = \frac{-6}{4}\\\\\boxed{m=-\frac{3}{2}}[/tex]
-14 = x - 12 PLS help ASAP and show checked solution
Answer:
The correct answer is x = -2.
Step-by-step explanation:
To solve this equation, we must remember that it is our end goal to get the variable x alone on one side of the equation.
To do this, our first step should be to add 12 to both sides of the equation to cancel the -12 on the right side. This is modeled below:
-14 + 12 = x - 12 + 12
If we add together the like terms to simplify, we get:
-2 =x
This is our answer. To check that our answer is correct, we can plug in the value we obtained for x back into the original equation.
-14 = x - 12
-14 = -2 - 12
-14 = -14
Since plugging in our value for x yielded a true statement, we can conclude that our answer is correct.
Hope this helps!

There are 11 coins in total. Aditi!S piggy bank has $1.85. The coins are either quarters or dimes.How many of each coin are there. Solve with elimination.
Hey there! I'm happy to help!
Let's represent our number of quarters with q and our dimes with d. We know that each q has a value of 0.25, and each d has a value of 0.1. This means that 0.25q+0.1d=1.85. We also know that q+d=11 as there are 11 total coins.
Here is our system of equations.
0.25q+0.1d=1.85
q+d=11
We are asked to solve with elimination. To do this, we need combine the equations to cancel out a variable to solve for the other. We have 1d on the bottom. Let's multiply the entire top equation by -10 to get a -1d on the top so we can do this.
-2.5q-d=-18.5
q+d=11
We combine the equations.
-1.5q=-7.5
We divide both sides by -1.5
q=5
Since there are 11 coins in total, this means that there are 5 quarters and 6 dimes.

Minato drove 390 miles. Part of the drive was along local roads, where his average speed was 20 mph, and the rest was along a highway, where his average speed was 60 mph. The drive took 8 hours. What distance, in miles did Minato drive along local roads?
Answer:
45 miles.
Step-by-step explanation:
Given that the:
Total distance covered = 390 miles
Total time = 8 hours
Let the distance covered along the local way = L
And the distance covered along the highway = H
Along with local way,
Speed = distance/ time
20 = L / T
T = L /20 .... (1)
Along the highway,
Distance covered H = 390 - L
Let the time = t
Speed = distance/time
60 = (390 - L)/t
t = ( 390 - L)/60
But total time = T + t
That is
8 = L/20 + (390 - L)/60
The LCM at right hand side will be 60
8 = ( 3L + 390 - L )/60
Cross multiply
480 = 2L + 390
Collect the like terms
2L = 480 - 390
2L = 90
L = 90/2
L = 45 miles.
Therefore, the distance Minato drive along local roads is 45 miles
