Answer:
[tex]S_3=35[/tex]
Step-by-step explanation:
Given: [tex]S_1=3\,,S_n=7(S_{n-1}-2)[/tex]
To find: [tex]S_3[/tex]
Solution:
First find [tex]S_2[/tex]
Put [tex]n=2[/tex] in [tex]S_n=7(S_{n-1}-2)[/tex]
[tex]S_2=7(S_{2-1}-2)\\S_2=7(S_1-2)[/tex]
Put [tex]S_1=3[/tex]
[tex]S_2=7(3-2)=7[/tex]
Now find [tex]S_3[/tex]
Put [tex]n=3[/tex] in [tex]S_n=7(S_{n-1}-2)[/tex]
[tex]S_3=7(S_{3-1}-2)\\S_3=7(S_{2}-2)[/tex]
Put [tex]S_2=7[/tex]
[tex]S_3=7[(7)-2]=7(5)=35[/tex]

An arithmetic sequence is represented by the explicit formula A(n) = 2 +(n − 1)(− 5)
What is the recursive formula?
Answer:
a+(n-1)d please do you get it or
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5
Step-by-step explanation:
Given the explicit formula
A(n) = 2 - 5(n - 1)
Compare with the standard form
A(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 5
A recursive formula allows a term in the sequence to be found by adding d to the previous term.
Then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5 , with a₁ = 2

Step-by-step explanation:
The Stone's are driving to a family reunion that is 320.6 miles away. They
stop at a gas station and the map says they have 189.75 miles of the trip
remaining. How many miles have the Stone's driven so far?
DUE TODAY!
Answer:
Step-by-step explanation:
Formula
Driven = Total - what they need to go
Driven = 320.6 - 189.75
Driven = 130.85

Solve the system of equations by substitution.
3x+2y=10 y=3x-4
x= y=
Answer:
x=2; y=2
Step-by-step explanation:
3x+2y=10
y=3x-4
We can substitute y from the first equation with the second equation:
3x+2(3x-4)=10
3x+6x-8=10
9x=18
x=2
Now plug this in to any of the equations (i used second equation):
y=3(2)-4
y=6-4
y=2
Check your answers:
y=3x-4
2=3(2)-4
2=6-4
2=2

Step-by-step explanation:
4x + 3 = x + 2(x + 7)
step by step
Answer:
x=11
Step-by-step explanation:
4x + 3 = x+ 2x + 14
4x + 3 = 3 x + 14
4x - 3x = 14 -3
x= 14 - 3
x= 11
Answer:
x=11
Step-by-step explanation:
Distribute :
4x + 3 = x + 2( x+ 7)
4x + 3 = x + 2x + 14
Combine like terms :
4x + 3 = x + 2x + 14
4x + 3 = 3 x+ 14
Subtract 3 from both sides of the equation :
4x + 3 = 3x + 14
4x + 3-3 = 3x + 14 -3
Simplify :
what ever way you know how to subtract the numbers you should get this answer :
4x = 3x + 11
Subtract 3 from both sides of the equation :
4x = 3x + 11
4x - 3x = 3x + 11 - 3x
Simplify :
combine like terms
multiply by 1
combine like terms
x= 11
4. The population of a small town is given by the function p=35t +1450, where t is the number
of years since 2015. What would the town's population be in 2020?
(1) 1,485
(3) 1,625
(2) 1,570
(4) 1,700
Answer:
1625
Step-by-step explanation:
[tex]35(5) + 1450 = 1625[/tex]
35 x 5 = 175
175 + 1450 = 1625

Starbucks sells 26 drinks every 2 hours. How many drinks would they sell in 12 hours?
Answer:
156 Drinks
Step-by-step explanation:
Answer:
No. of drinks sell by them in an hour=26/2=13
So,No. of drinks sell by them in 12 hours=
[tex]12 \times 13 = 156[/tex]
Hence, They sell 156 drinks in 12 Hours and 312 drinks in a day.
Gotta love these Starbucks lover, they'll tell you I'm insaneA line has a slope of O and passes through the point (-8, 10). What is its equation in
slope-intercept form?
Answer:
Slope-intercept form: y = 10 Point-slope form: y − 10 = 0 ⋅ ( x + 8 )
Step-by-step explanation:
I need help find this in slope intercept form
Answer:
y=2x+24 is you're answer
Answer:
I'm pretty sure it's y=2x+24
Step-by-step explanation:
The slope intercept formula is y=mx+b. So to get the equation into that form you would have to get y by itslef, which means you would have to subtract 8x from both side. And then you can't have a number in front of the y so you have to divide by that for all of the terms.This then gives you your answer.

Answer:
1. adjacent: ACB, BCD and BCD, DCE. vertical: ACB, DCE and BCD, ECA
2. adjacent: KGJ, JGI and HGM, MGK. vertical: JGI, MGL and HGM, KGJ
3. adjacent. x = 49°
4. adjacent. x = 71°
Step-by-step explanation:
As I noted in the attachment, vertical angles are formed from opposite rays (lines that cross). They share only a vertex. Each of the crossing lines makes up one side of each of the vertical angles. (You can think of each line as being made of opposite rays from the vertex of the angle.)
Adjacent angles share both a vertex and one side. (They do not overlap.) For example, in Figure 2, angles KGM and LGM are not adjacent, even though they share verex G and side GM. This is because they overlap. In that figure, angles KGL and LGM are adjacent angles.
__
1. To identify adjacent angles, choose a ray and make note of the angles on either side of it.
adjacent: {ACE, ACB}, or {BCA, BCD}, or {DCB, DCE}, or {ECD, ECA}
To identify vertical angles, choose two crossing lines and one of the 4 spaces between them. The other vertical angle will be non-adjacent, in the opposite space of the same size.
vertical: {ACB, ECD}, or {ACE, BCD}
__
2. adjacent: any of the pairs {KGJ, JGI}, {JGI, IGH}, {IGH, HGM}, {HGM, MGL}, {MGL, LGK}, {LGK, KGJ}.
Note that these are the nearest, smallest pairs of adjacent angles. This is usually what we are talking about when we refer to adjacent angles. We could add to the list pairs like {IGH, IGK}, {IGM, IGL}.
vertical: (lines IL, HK) {IGH, LGK} or {IGK, LGH}; (lines IL, MJ) {IGM, LGJ} or {IGJ, MGL}; (lines HK, MJ) {HGM, KGJ} or {HGJ, KGM}
__
3. The angles share a ray, so are adjacent. Together, they make up a right angle, so they are complementary.
x = 90° -41°
x = 49°
__
4. The angle share a ray, so are adjacent. Together, they make up a linear angle, so are supplementary.
x = 180° -109°
x = 71°

Mr. Turner has two Math 2 classes, with one class, he lectured, and the students took notes.
In the other class, the students worked in small groups to solve math problems. After the first
test, Mr. Turner recorded the student grades to determine if his different styles of teaching
might have impacted student learning,
Class 1: 80, 81, 75, 70, 72, 74, 76, 77, 77, 79, 84, 88, 90, 80, 78
Class 2: 70, 90, 88, 89, 86, 86, 82, 77, 79, 84, 84, 86, 87, 88, 88
The sum of two numbers is 25. The difference between twice the first number and the second number is -10. Find the numbers
Answer:
15 and 10
Step-by-step explanation:
Let the two numbers be x and y
x+y= 25
2x-2y=-10
2x+20 3x-15 solve for x=?
Answer:
X = 35
Step-by-step explanation:
Since the line is crossing two parallel lines the measurements are equal then you solve for X.
2X + 20 = 3X - 15
-2X -2X
20 = X - 15
+15 +15
35 = X
Answer:
x=35
Step-by-step explanation:
The expressions are corresponding angles which are congruent.
Set the two equations equal to each other.
2x+20=3x-15
Add and subtract like terms
35=1x
Divide:
35/1=35
X=35

Write the following quadratic expression in standard form: ( 2 x − 1 ) ( 3 x − 1 )
Answer:
6[tex]x^{2}[/tex] - 5[tex]x[/tex] + 1
Step-by-step explanation:
Standard form is: [tex]ax^{2} +bx+x[/tex]
To reach that you have to distribute:
(2x - 1) (3x - 1)
2x (3x - 1) = 6[tex]x^{2}[/tex] - 2[tex]x[/tex]
-1 (3x - 1) = -3[tex]x[/tex] + 1
Combine like terms:
6[tex]x^{2}[/tex] - 5[tex]x[/tex] + 1
