Answer:
x<4
Step-by-step explanation:
3x < 12
Divide with 3 on each side
x< 4
In words x has all the real numbers that are less than 4 or x belongs to any number from -ve infinity to 4.
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
To graph the inequality 3x < 12 on a number line, we can follow these steps:
- Start by isolating x by dividing both sides of the inequality by 3, which gives us x < 4.
- Draw a number line and mark a point at 4, which is the boundary between the values of x that satisfy the inequality and those that don't.
- Since the inequality is strict (i.e., "less than" and not "less than or equal to"), we need to indicate that the point x = 4 is not included in the solution set.
We can do this by making an open circle (or "unfilled dot") at 4 on the number line.
- Shade the portion of the number line to the left of the point x = 4, since these are the values of x that satisfy the inequality 3x < 12.
We can use an arrow pointing to the left to indicate that the shaded region extends indefinitely in that direction.
Thus,
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.

How many solutions does this equation have? -2-5x= -(5x+2)
Answer:
Infinite solutions
Step-by-step explanation:
A linear equation is given to us and we need to tell the no. of solutions. The equation is ,
=> -2-5x = - ( 5x +2)
If we look at RHS , negative sign is present outside the brackets .On opening the brackets , we have ,
=> -(5x) -(+2)
=> -5x -2
=> -2 - 5x
This is similar to LHS and hence they will represent same line . Hence they will have infinitely many solutions .
They have infinitely many solutions .The length of a rectangular lot is 6 feet less than 3 times its
width. Its area is 222 square feet.
Its width is
feet and its length is
feet.
Answer:
Length = 22.98 feet
Width = 9.66 feet
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Area of rectangle = 222 feet²
Translating the word problem into an algebraic expression, we have;
L = 3W - 6 ...... equation 1
We know that the area of a rectangle is given by the formula;
A = L * W
Substituting
222 = L * W ....equation 2
Substituting eqn 1 into eqn 2, we have;
222 = (3W - 6) * W
222 = 3W² - 6W
Rearranging the equation, we have;
3W² - 6W - 222 = 0
Next, we would use the quadratic formula to solve for the roots.
Note: the standard form of a quadratic equation is ax² + bx + c = 0
a = 3, b = -6 and c = -222
Solving the quadratic equation using the quadratic formula;
The quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex] x = \frac {-(-6) \; \pm \sqrt {6^{2} - 4*3*(-222)}}{2*3} [/tex]
[tex] x = \frac {6 \pm \sqrt {36 - (-2664)}}{6} [/tex]
[tex] x = \frac {6 \pm \sqrt {36 + 2664}}{6} [/tex]
[tex] x = \frac {6 \pm \sqrt {2700}}{6} [/tex]
[tex] x = \frac {6 \pm 51.96}{6} [/tex]
[tex] x_{1} = \frac {6 + 51.96}{6} [/tex]
[tex] x_{1} = \frac {57.96}{6} [/tex]
x1 = 9.66
We do not need the negative value of x, so we proceed.
Therefore, Width, W = x1 = 9.66 feet
For the length;
L = 3W - 6
L = 3(9.66) - 6
L = 28.98 - 6
L = 22.98 feet

The survey was done to test the suggestion that the proportion of younger adults who use their horn is greater than the proportion of older adults who use their horn. Which of the following represents the hypotheses that we will be testing, assuming that p1 represents the population proportion of all young adults 20-39 who report using their horns and that p2 represents the population proportion of all older adults 60+ who report using their horns?
a. H0: p1=p2 versus Ha: p1>p2
b. H0: p1=p2 versus Ha: p1
c. H0: p1=p2 versus Ha: p2>p1
d. H0: p1=p2 versus Ha: p1=/=p2
Answer:
a. H0: p1=p2 versus Ha: p1>p2
Step-by-step explanation:
Given that
p1 represent the proportion of the population for young allots 20-39
And, p2 denotes the proportion of the population for all older adults that are above 60
So,
We need to find out the hypotheses
The null & alternative hypothesis is
H_o: P_1 = P_2
H_a: P_1>P_2

Penny works 44 hours at an hourly rate of $8.50. She was paid time and a half for the overtime of 4 hours. What were her total wages?
Answer:
Time and a half pay is 50% more than an employee's regular rate of pay. For every hour of overtime an employee works, you must give them their regular rate of pay plus half of that. To calculate an employee's overtime rate of pay, multiply their regular rate by 1.5.

Don invested $ 5 000 in an account paying 5% simple interest per year for 7 years.
Answer:
FV= $6,750
Step-by-step explanation:
Giving the following information:
Initial investment (P)= $5,000
Interest rate (r)= 5% simple interest
Number of periods (t)= 7 years
To calculate the future value of the investment, we need to use the following formula:
FV= (P*r*t) + P
FV= (5,000*0.05*7) + 5,000
FV= 1,750 + 5,000
FV= $6,750

A motorboat travels 102 miles in 3 hours going upstream. It travels 186 miles going downstream in the same amount of
time. What is the rate of the boat in still water and what is the rate of the current?
Rate of the boat in still water:
Rate of the current:
Answer:
Rate in still water = 48 mph.
Rate of current = 14 mph.
Step-by-step explanation:
Let the rate in still water be x and rate of the current be y miles per hour.
Upstream:
x - y = 102/3
Downstream:
x + y = 186/3
Adding the 2 equations
2x = 102/3 + 186/3 = 34 + 62
2x = 96
x = 48 mph.
So 48 - y = 34
y = 48 - 34 = 14 mph.
What is the magnitude of -5+ 12i?
Here the picture, :D
The magnitude of the complex number -5 + 12i is 13 which we obtained by using formula, Magnitude [tex]= \sqrt{ a^2 + b^2}[/tex].
To find the magnitude of a complex number in the form of a+bi, where a and b are real numbers, the formula can be used is:
Magnitude = |a+bi|
[tex]= \sqrt{ a^2 + b^2}[/tex]
The given complex number is -5 + 12i.
we have a = -5 and b = 12.
Plugging these values into the formula, we get:
Magnitude = | -5 + 12i |
[tex]= \sqrt{ (-5)^2 + 12^2}[/tex]
[tex]= \sqrt{ 25 + 144}[/tex]
[tex]= \sqrt{ 169}[/tex]
= 13
Therefore, the magnitude of -5 + 12i is 13.
