to get the equation of any straight line we simply need two points off of it, hmm let's get two from this table
[tex]\begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} 0&4\\ 1&10\\ 2&16\\ 3&22\\ 4&28\\ \cline{1-2} \end{array} \begin{array}{llll} \\ \leftarrow \textit{let's use this point}\\\\ \leftarrow \textit{and this point} \end{array}[/tex]
[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{22}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{22}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{12}{2}\implies 6 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{6}(x-\stackrel{x_1}{1}) \\\\\\ y-10=6x-6\implies y=6x+4[/tex]

Given a geometric sequence with a1=5 and a4=135 find a2.
Answer:
15
Step-by-step explanation:
Terms in a geometric series that are n apart will have a ratio that is r^n. Here we have terms a4 and a1, which are 4-1=3 apart, so their ratio is ...
a4/a1 = 135/5 = 27 = r^3
r = ∛27 = 3
The second term is the first, multiplied by this common ratio:
a2 = a1·r = 3(5)
a2 = 15

C: Those who like Hamburgers but not burritos.
Step-by-step explanation:
Like Hamburgers ↓ Does Not Like Hamburgers↓ Total↓
Likes burritos → 39 38 77
Does not like burritos → 95 33 128
Total → 134 71 205
So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 39 like Hamburgers.A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining 33 do not like Hamburgers.A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.Part A: The percent of respondents who do not like hamburgers and burritos both
There are 33 such respondents.
Hence, percentage 33/205 * 100 = 16.09%
Part B: Marginal relative frequency of all customers that like hamburgers
It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents
Hence, ratio 134/205 = 0.65
Part C: The data point that has the strongest association of its two factors.
For this, we need to find the ratio of all the four data with the total.
Those who like Hamburgers and burritos: 39/134 = 0.29
Those who like Hamburgers but not burritos: 95/134 = 0.71
Those who like burritos but not Hamburgers: 38/71 = 0.53
Those who do not like burritos or Hamburgers: 33/71 = 0.47
So, the answer is those who like Hamburgers but not burritos.
Solve x÷2<4. Graph the solution.
Answer:
The solutions are (-2, 0) and (1, 3).
Step-by-step explanation:
Edginuity Sample response: The graph consists of a parabola and a line. The parabola opens down and has a vertex of (0, 4). The line has a slope of 1 and a y-intercept of 2. We want to solve
-x² + 4 = x + 2
Create two curves as follows:
y = -x² +4
and
y = x + 2
By graphing the two curves together, their points of intersection are the solutions.
y = -x² + 4 is a parabola with vertex at (0, 4), and it opens downward.
y = x + 2 is a straight line with slope - 1 and with y-intercept = 2
The points of intersection are (-2, 0) and (1, 3).
What is the answer to this quadratic equation: 6x² + 11x – 35
Answer:
Step-by-step explanation:
This thing looks like you have to use the quadratic equation to solve it. You don't. It will factor. but you might have to guess a bit.
(3x )(2x )
(3x - 5 ) (2x + 7) How lucky is that!!?
Remove the Brackets
3x * 2x + 3x*7 - 5*2x - 35 Combine
2x*3x^2 + 21x - 10x - 35
6x^2 + 11x - 35
So the guess turns out to be correct. Now we need to solve for the roots.
3x - 5 = 0 Add 5 to both sides.
3x = 5 Divide by 3
x = 5/3
x = 1.6667
2x + 7 = 0 Subtract 7 from both sides
2x = - 7 Divide by 2
2x/2 = - 7/2
x = - 3.5
Answer
x = 1.667 orx = - 3.5

7c+5=9(c−3)
Answer:
c = 16
Step-by-step explanation:
First, distribute the 9 to the parentheses:
7c + 5 = 9(c − 3)
7c + 5 = 9c - 27
Then, subtract 7c from both sides:
5 = 2c - 27
Add 27 to both sides:
32 = 2c
Divide each side by 2:
16 = c
So, c = 16

The local furniture store pays $120 for a lamp and sells it with a 20% markdown. What is the
selling price of the lamp?
Answer:$24
Step-by-step explanation:
To find 20 percent of a number you multiply the number by 20, then multiply the answer by .01.
120 x 20 = 2400
2400 x .01 = 24
Answer: I think its 24 tell me if I'm wrong
20 divided by 100 gives you 0.2
0.2x120 gives you 24
If two sides in one triangle are 9 and 21 , then the third side might be
a) 9
b) 11
c) 12
d) 13
please explain how you got the answer in details I'm completely lost
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

1/3(y+7)=3(y−1)
Solve for y
Answer:
2
Step-by-step explanation:
multiplying each number by 1/3 gives
1/3y+7/3= 3y-3
3y-1/3y=7/3+3
8/3y=16/3
y=16/3÷8/3
y=16/3×3/8
y=2
The solution of the equation 1/3(y+7)=3(y−1) will be ; y = 2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the equation is 1/3(y+7)=3(y−1)
First, multiplying each number by 1/3 gives;
1/3y+7/3= 3y-3
3y-1/3y=7/3+3
8/3y=16/3
Cross multiplication;
y=16/3÷8/3
y=16/3×3/8
y=2
Therefore, the solution of the equation 1/3(y+7)=3(y−1) will be ; y = 2
