Answer: Vertical line x = 1
Step-by-step explanation:
(1, 1) (1, 2) (1, 3) (1, 4)
Notice that the x-value for each coordinate is 1.
The line is a vertical line (up & down) through x = 1
Answer:
it's not an up and down line, the graph is a group dots (4 ones) that they are located on a vertical line

Answer:
14/2187
Step-by-step explanation:
Let us first see how many possible outcomes there are. We can to that by multiplying 9^4. This gives us 6561.
Now, we can see what are the possible outcomes that meet the requirements. We can get this by multiplying 1 • 1 • 7 • 6, which is 42.
Our fraction is 42/6561, which is 14/2187.

Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms. He gets paid $2 for every candy bar he sells, and he made a total of $90 on Saturday. Write an equation to show how many candy bars Brady sold on Saturday.
Answer: 2x = $90
Step-by-step explanation:
From the question, we are informed that Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms and that he gets paid $2 for every candy bar he sells, and he made a total of $90 on Saturday.
The equation showing the number of candy bars Brady sold on Saturday goes thus:
Let the number of candy bars sold on Saturday be x.
Since each candy bar is sold for $2 and he made a total of $90, this means that the $90 gotten is the product of each candy bar and the amount sold which we represented by x. Therefore the equation will be:
2 × x = $90
2x = $90
We can further solve to get x.
2x = 90
x = 90/2
x = 45
That means 45 candy bars were sold.
Answer:
hi, so i belive the correct option to your question is:
2x = 90
Step-by-step explanation:
it just makes the most sense to me because 2x which could mean two times which in the equation it says he makes to dollars per candy bar sold, so it makes more sence for it to be 2x rather than 90x. and then it says he made a total of ninty dollars on saturday which is a key factor in solving this equation so think it would be 2x = 90$.
im really not sure if this logic makes sence, im not super good with algebra but i hope this helps you out.

On a map, 1 cm represents 3 km. The real-life distance between two towns is 27 km. What is the distance between these two towns on a map?
Answer:
9 cm
Step-by-step explanation:
Every centemeter represents three. 3km=1cm.
The number of kilometers/3= the number of centemeters.
the number of centemeters x 3= the number of kilometers.
We now have three equations to help us covert back and forth.
The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)
The number of kilometers/3= the number of centemeters.
27/3=the number of centemeters.
Thus, the answer is nine.
Answer:
9cm
Step-by-step explanation:
1:3 this is the starting ratio
if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.

Um avião partiu de um aeroporto situado a 800 metros acima do nível do mar, com o tempo bem e a temperatura de 32° C. Ao atingir a altitude máxima, de 3 100 metros acima do nível do mar, o piloto observou que a temperatura externa era de – 41° C. Da decolagem até o momento em que foi atingida a altitude máxima, a variação da temperatura externa foi de:
Resposta: 73 ° C
Explicação passo a passo:
Dado o seguinte:
Temperatura (T1) na decolagem localizada a 800 metros acima do nível do mar = 32 ° C
Temperatura (T2) à altitude máxima de 3200 metros acima do nível do mar = - 41 ° C
Portanto ;
A variação da temperatura externa entre o ponto de decolagem e a altitude máxima pode ser calculada por:
Diferença entre a temperatura de decolagem e a temperatura na altura máxima.
Variação externa da temperatura = (T1 - T2)
32 ° C - (-41 ° C)
= 32°C + 41°C
= 73°C

Farah would pack 161616 outfits for a 121212-day vacation.
(Choice E)
E
Farah would pack 282828 outfits for a 212121-day vacation.
Answer:
Choices B, D and E.
Step-by-step explanation:
This is simple logic.
If it was choice A, number of outfits won't be lower than number of days.
Choice B is right, because if you do this:
(3×2)(3×2)(3×2)=666 days
or
6÷3=2
(4×2)(4×2)(4×2)=888 outfits
or
8÷4=2
You would know the statement is true.
If it was choice C, it's not correct:
(3×3)(3×3)(3×3)=999 days
(4×3)(4×3)(4×3)=121212 outfits (this is the closest answer because nothing can be multiplied by 4 to get 101010)
So, statement of choice C is incorrect.
Choice D is correct, because of this:
(3×4)(3×4)(3×4)=121212 days
or
12÷3=4
(4×4)(4×4)(4×4)=161616 outfits
or
16÷4=4
E is also correct, because of this:
(3×7)(3×7)(3×7)=212121 days
or
21÷3=7
(4×7)(4×7)(4×7)=282828 outfits.
So the answer is choices B, D and E.

Which group of numbers is ordered from least to greatest?
A. 45,−0.9,−3
B. −3,−0.9,45
C. −0.9,45,−3
D. 45,−3,−0.9
Answer:
The answer is option B.
-3 , - 0.9 , 45
Hope this helps you
Explanation:
The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.

Answer:
first complete the table by filling blank space on y axis
Then choosing a suitable scale, two squared box on the graph paper represent 1 unit for both axis.
Then draw a graph using x and y coordinate
(b) minimum value of y you dote a line from the turning point of the curve towards y axis then read the value
For this case it is -3.2
(c).To get the value of y when X=-3.5,
you dote alone from X =-3.5 on the X axis towards the curve vertically until you meet the curve then from the meeting point dote a line towards y axis and read the value.
which gives y=0.8
(d). draw a horizontal line at y=3 to meet the curve on both sides then dote a line from the meeting point vertically towards X axis and read the value on the X axis.

The method you used to help Kevin in parts F and G is called cross multiplication. It’s called cross multiplication because it involves multiplying the denominator of each fraction with the numerator on the opposite side of the equal sign. Now solve the equation 24(9) = 2x.
Answer:
x = 108
Step-by-step explanation:
Start by finding what 2x equals
24 x 9 = 216
multiply 24 by 9 and you get 216
216 = 2x
now isolate for x by dividing both sides by 2, leaving x by itself on one side of the equation
216 / 2 = x
x = 108
Answer:
108=x
step-by-step explanation:
24(9)=2x
216=2x
216/2=2x/2
Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP
Answer:
Option (B)
Step-by-step explanation:
Given sequence is 45, 135, 405, 1215, 3645..........
Since it's a geometric sequence,
Common ratio of each successive term to the previous term
r = [tex]\frac{135}{45}=3[/tex]
First term of the sequence 'a' = 45
Explicit formula of a geometric sequence will be,
[tex]a_n=a(r)^{n-1}[/tex]
[tex]a_n=45(3)^{n-1}[/tex]
Recursive formula of this sequence will be,
[tex]a_n=3(a_{n-1})[/tex], [tex]a_1=45[/tex]

Hope this helps you.
Answer:
Simplifying
x = 2x + -21
Reorder the terms:
x = -21 + 2x
Solving
x = -21 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
x + -2x = -21 + 2x + -2x
Combine like terms: x + -2x = -1x
-1x = -21 + 2x + -2x
Combine like terms: 2x + -2x = 0
-1x = -21 + 0
-1x = -21
Divide each side by '-1'.
x = 21
Simplifying
x = 21

Use the result to estimate the limit. Use a graphing utility to graph the function to confirm your result. (Round your answer to four decimal places.)
[1/(x+1)] - (1/9)
X-8
Answer:
See below.
Step-by-step explanation:
We have:
[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right)[/tex]
Simply plug in each value:
When x = 7.9, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx 0.0012[/tex]
When x = 7.99, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0001[/tex]
When x = 7.999, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0000[/tex]
When x = 8.001, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0000[/tex]
When x = 8.01, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0001[/tex]
And when x = 8.1, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0012[/tex]
From this pattern, we can conclude that:
[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right) = 0[/tex]
Since as the limit approaches 8, the value gets smaller and smaller and approaches zero.
Graphing this, we can confirm our answer.
