Does anyone know how to solve |4x+3|-9<5
Answer in fraction form: -17/4 < x < 11/4
Answer in decimal form: -4.25 < x < 2.75
=======================================================
Work Shown:
|4x+3| - 9 < 5
|4x+3| < 5+9 .... adding 9 to both sides
|4x+3| < 14
-14 < 4x+3 < 14 .... see note at the bottom
-14-3 < 4x < 14-3 .... subtracting 3 from all sides
-17 < 4x < 11
-17/4 < x < 11/4 .... divide all sides by 4
-4.25 < x < 2.75
This says that x is between -4.25 and 2.75, but x is not equal to either endpoint.
Note: I used the rule that |x| < k becomes -k < x < k where k is a positive real number.
URGENT STAMPS Zoe added 23 tamps to her
collection., Three months later her
collection had tripled in number to a
total of 159 stamps. How many stamps
did Zoe have to start her collection?
Answer:
30
Step-by-step explanation:
x = original number of stamps
x+23 (added 23 stamps to the collection)
3(x+23) tripled in number
3(x+23) = 159
Divide each side by 3
3(x+23)/3 = 159/3
x+23=53
Subtract 23 from each side
x+23-23 = 53-23
x = 30
what is the domain of y=cos 0
Answer:
The domain of y = cos θ is all real numbers. This is because any real number can be plugged in for θ and y will be equal to a real number. This can be shown graphically because the y = cos θ will go on infinitely both to the right and left.

An ant walk about 3 inches per second how many miles per day could an ant travel if it walked without a break?
Answer:
Step-by-step explanation:
45/11 miles per day or ~4.091 miles per day
Step-by-step explanation:
3 inches per second
24 hours in a day
60 minutes in 1 hour
60 seconds in 1 minute
Amount of inches per minute: 3 x 60 = 180 inches
Amount of inches per hour: 180 x 60 = 10,800 inches
Amount of inches per day 10,800 x 24 = 259,200 inches
To find the number of feet that 259,200 inches is, divide by 12.
259,200/12 = 21,600 feet per day
To find the number of miles that 21,600 feet is, divide by 5280.
21,600/5280 = 45/11 = 4.09090909091 = ~ 4.091
So, an ant could walk 45/11 miles per day or ~4.091 miles per day if it walked without taking a break.
calculate the length of the legs of an isosceles triangle.The base is less than the other congruent legs by two units.The perimeter of the triangle is 22 meter .
Answer:
Sides = 8 each and base = 6
Step-by-step explanation:
Let congruent legs = x, then the base is x - 2 so,
P = x + x + (x - 2)
22 = 3x - 2
24 = 3x
8 = x (sides)
base = 8 - 2 = 6

Answer:
x = 60
y = 60
Step-by-step explanation:
To find y (y and 120 are supplementary angles):
y + 120 = 180
y = 180 - 120
y = 60
x = y (because of corresponding angles)
x = 60

The new graph is the inverse of the time vs height graph, but I’d not a function. How would you restrict the domain on the original function to make it invertible?
Using inverse function concepts, it is found that the domains that make the function invertible are: [tex]t \in [0, 2.5][/tex] of [tex]t \in [2.5, 5][/tex].
-----------------------------------
A function is invertible if each output is related to only one value of the input.-----------------------------------
In the graph given in this question, other than the maximum height at [tex]t = 2.5[/tex] seconds, all outputs are related to two input values.To be invertible, the domain has to be divided at the half-way point, either between 0 and 2.5 seconds, or between 2.5 seconds and 5 seconds. This way, each output will be related to only one input.Thus, the domains that make the function invertible are: [tex]t \in [0, 2.5][/tex] of [tex]t \in [2.5, 5][/tex].

What is the relationship between the number of sides in a regular polygon and
number of lines of symmetry?
Answer:
Divide 360 by the difference of the angle and 180 degrees. For example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

If angle 1 and angle 2 are vertical angles, and the m<1 = 10x - 9 and m<2 = 4x + 15. Find the value for x.
Answer:
x = 4
Step-by-step explanation:
Vertical angles are equal.
m∠1 = m∠2
10x - 9 = 4x + 15
Add 9 to both sides
10x = 4x + 15 + 9
10x = 4x + 24
Subtract 4x from both sides
10x -4x = 24
6x = 24
Divide both sides by 6
x = 24/6
x = 4
PLS HELP A student is assessing the correlation between the number of workers in a factory and the number of units produced daily. The table shows the data:
Number of workers
(x) 0 10 20 30 40 50 60 70 80 90
Number of units
(y) 2 52 102 152 202 252 302 352 402 452
Part A: Is there any correlation between the number of workers in a factory and the number of units produced daily? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answer:
Part A: Yes. There is a correlation between the number of workers in a factory and the number of units produced daily.
Part B: The equation of the function that best fits the data is
Part C: The slope is which indicates the rate of change of number of units produced daily over the change in number of workers. The y - intercept is which indicates the number of units produced by number of workers.
Explanation:
Part A: To determine the correlation coefficient, first we shall find the slope and y - intercept.
Let us substitute the coordinates and in the slope formula, to find the value of slope.
Hence, we have,
Thus, the slope is
The y - intercept is the value of y when the value of x is equal to 0.
Thus, from the table , we can see that when , the value of y is 2
Hence, the y - intercept is
Substituting the values and in the slope intercept form , we get,
Hence, there is a linear correlation between the number of workers in a factory and the number of units produced daily.
Part B: To find the function that best fits the data, let us substitute the value of slope and y - intercept in the slope intercept formula.
Since, we have already found slope and y - intercept
Substituting these values in the slope intercept form , we get,
Thus, the function that best fits the data is
Part C:
The slope is
The slope indicates that the rate of change of number of units produced daily over the change in number of workers.
The y - intercept is
The y - intercept indicates that the number of units produced by number of workers.
Step-by-step explanation:
A. Yes. B. A linear function of the form y = 5x + 2 can best fit the data. C. The slope (m) of the plot indicates the rate of change in the number of units produced per worker. The y-intercept (b) indicates the number of units produced when there are zero workers.
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
Part A:
Yes, there is a positive correlation between the number of workers in a factory and the number of units produced daily. As the number of workers increases, the number of units produced also increases.
Part B:
A linear function of the form y = 5x + 2 can best fit the data, which is determined by the two points (10, 52) and (50, 252).
Part C:
The slope of the plot indicates the rate of change in the number of units produced per worker. The y-intercept indicates the number of units produced when there are zero workers. The slope and y-intercept together describe the overall trend of the data and can be used to make predictions about future production levels.
