–6 < 3x – 12 ≤ 9
Answers
Answer:
second graph
Step-by-step explanation:
Solving the inequality
- 6 < 3x - 12 ≤ 9 ( add 12 to all 3 intervals )
6 < 3x ≤ 21 ( divide the intervals by 3 )
2 < x ≤ 7
The graph has an open circle at 2 and a closed circle at 7
This is represented on the second graph

A new bagel store opened. The first day 15 customers entered the store. The number of
customers that enter the store triples each day after. Which function represents f(d), the
number of customers that enter on the d day?
1.
f(d) = 3(15)
2.
f(d) = 3d + 15
3
f(d) = 150 + 3
f(d) = 15(3)
Submit Answer
Answers
Answer:
[tex]f(d) = 15 + 3d[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] --- day 1
[tex]Rate = 3[/tex] -- i.e. triples daily
Required
Determine the function f(d)
The number of customers on a particular day is:
Customers = Day 1 + Rate * Number of days
Represent as a function:
[tex]f(d) = a + Rate* d[/tex]
Where d is the number of days.
So, we have:
[tex]f(d) = 15 + 3* d[/tex]
[tex]f(d) = 15 + 3d[/tex]

Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

Answers
Answer:
Solution for 17=w-4 equation:
17=w-4
We simplify the equation to the form, which is simple to understand
17=w-4
We move all terms containing w to the left and all other terms to the right.
-1w=-4-17
We simplify the left and right sides of the equation.
-1w=-21
We divide both sides of the equation by -01 to get w.
w=21

Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)
__
This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form

Use the x-intercept method to find all real solutions of the equation.
x? - 7x2 + 4x + 12 = 0
Answers
Correct equation is;
x³ - 7x² + 4x + 12 = 0
Answer:
All the real solutions are -1, 2 and 6
Step-by-step explanation:
The x-intercept of x³ - 7x² + 4x + 12 = 0 will occur where y is zero. This is where the curve crosses the x-axis on the graph of this function.
Now, I have plotted a graph of this function and attached it.
From the attached image, the curve crosses the x - axis at the points, x = -1, x = 2, x = 6.
Therefore all the real solutions are -1, 2 and 6
1. In 1980, approximately 6 million women enrolled in college in the United States. The number of women who enroll in college has increased at a rate of 0.14 million women per year. There were about 5.4 million men enrolled in college in 1980, and that number has increased at a rate of 0.08 million men per year. In what year (prior to 1980) were an equal number of men and women enrolled in college?
Answers
Answer:
Step-by-step explanation:
First, you can plot this using a table. One side can be 'Women' and the other 'Men'. One the vertical side of it, write '1980', '1981', '1982', etc., for maybe fifteen years to be on the safe side. Then, your starting value is 6 million and 5.4 million, respectively.
Finally, start adding up, It will be, 6.14 million, 6.28 million, etc., and 5.4 million, 5.48 million, etc.
Once you're done, you can circle the year both were the same, and you can even plot this on a graph

Janie ordered boxed lunches for a student advisory committee meeting. Each lunch costs $4. The total cost of the lunches is $47, including a $7 delivery fee. Write and solve an equation to find x, the number of boxed lunches Janie ordered.
Answers
Answer:
10 lunches
Step-by-step explanation:
$47-$7=$40
40/4=10
Hello, 928747!
So we are trying to find how many boxed lunches Janie ordered.
Each box is $4.00 and the total cost is $47.00 + delivery fee of $7.00
So to find this, we will first subtract the delivery fee because that does not count towards the lunches.
47 - 7 = 40
So the boxed lunches cost $40.00
To find how many Janie ordered, we will divide 4 by 40
40 ÷ 4 = 10
So Janie bought 10 boxed lunches.
The equation would be (47 - 7) ÷ 4

According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
