Answer:
inequality: x > -3
Set notation: {x: x> -3}
Interval notation: [-3, ∞)
The interval can be described as inequality is x>-3, the set notation is {x: x>-3}, and the interval notation is [-3, α).
Which numbers can be shown on a number line?The positive, negative, whole, and rational numbers can be mark on a number line. Numbers appearing on the right side of 0 are positive, and those reflected on the left side are negative.
The thick line on the picture starts at -3 and tends towards positive infinity. So, it can be represented as inequality by x>-3.
The set notation can be described for x-axis elements since it is a line. The elements greater than -3 are present in it. So it can represented as {x :x> -3}.
The interval ranges from -3 to positive infinity; hence, it can be represented as [-3,α).
So we can conclude that the interval can be represented by an inequality as x > -3, the set notation contains elements greater than -3, and the interval ranges from -3 to positive infinity.

The profit from a business is described by the function P(x) = -x^2 + 10x - 4, where x is the number of items made, in thousands, and P(x) is the
profit in dollars. How many items will maximize the profit?
A 5,000
B. 10,000
C. 20,000
D. 50,000
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)
What is Profit ?The money that you make when you sell something for more than it cost you.
For given example,
profit is described by the equation :
[tex]P (x) = -x^2 + 10x -4[/tex]
We need to maximize the profit P(x)
[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]
since , x is the number of items made in thousand
Therefore, 5000 items can maximize the profit

What is 3,700,000 in scientific notation??
=========================================================
Explanation:
Place a decimal point between the first two digits 3 and 7.
Now ask yourself how you can go from 3.7 back to the original value. Notice we can move the decimal point 6 spots to the right to go from 3.7 back to 3,700,000
Therefore, the exponent over the 10 is 6. The exponent is positive to mean we move the decimal point to the right. If we had a negative exponent, then we'd move left.
You can use a calculator to confirm that 3.7 * 10^6 = 3,700,000
--------------
Side notes:
3,700,000 = 3 million, 7 hundred thousand
3,700,000 = 3.7 million

Answer:
Use Simple Interest Formula=PrT/100
SI=$1800×5×6/12÷100
=4500/100

$45 is the interest that's gonna be owed after 6months so therefore the total $ she owed after 6 months would be: $45 + $1,800=$1,845.
Anna truncated the decimal expansion of x to find the best approximation. On a number line, the location of x is between 10.9 and 11.1. What is the BEST estimate of the value of x? A) 115 B) 118 C) 120 D) 125
Answer:
probably √125
Step-by-step explanation:
so x is between 10.9 and 11.1
What i did was added those to together and then divided them by 2 so that i could find the average between them:
10.9 + 11.1 = 22
22/2=11
so you have 11 as your average.
now what i did was find the value of each answer choice to see which one was closest to 11 and the square root of 125 is just that.
The best approximation of decimals 10.9 and 11.1 is 11.
What is a number line?In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given that, location of x in number line
x = 10.9 and x = 11.1
Now, to estimate the value we will round up both digits and find the average.
In 10.9 round up to 11 and 11.1 will round down to 11
Now average = (11 +11)/2 = 11
Therefore, the best approximation of decimals 10.9 and 11.1 is 11.

Hope this helps you. I apologize if it’s incorrect.
Answer:
x = 6/k
Step-by-step explanation:
kx + 12 = 3*kx
to make like terms on same side shift kx to right hand side . when u shift positive kx to other side it becomes negative
12 = 3kx - kx
12 = 2kx
shift 2 to left hand side when u shift multilication changes to division.
12/2 = kx
6 = kx
to find x u must shift k to other side . here also same since k and x are multilied when k shifts to others side it becomes divisor.
6/k = x

The radius of a circle is 4 meters. What is the area of a sector bounded by a 135° arc?
Give the exact answer in simplest form.
Answer:
The area of the sector of the circle is approximately
Step-by-step explanation:
The given parameters of the circle having a shaded sector are;
The radius of the circle, r = 4 meters
The measure of the arc bounding the sector = 135°
The area of a sector of a circle, 'A', is given as follows;
[tex]A = \dfrac{\theta}{360 ^{\circ}} \times \pi \times r^2[/tex]
Therefore, the area, 'A' of the given sector of the circle, is given as follows;
[tex]A = \dfrac{135 ^{\circ}}{360 ^{\circ}} \times \pi \times (4\ cm)^2 \approx 18.85 \ cm^2[/tex]
The area of the sector of the circle, with radius 4 cm and bounded by an arc, A ≈ 18.82 cm².

The inverse of the function f(x) = one-half x plus 10 is shown. h(x) = 2x- What is the missing value? 1 5 10 20
Answer:
20
h(x) = 2x - 20
Step-by-step explanation:
f(x) = ¹/₂ x + 10
First, isolate x, like so:
f(x) - 10 = ¹/₂ x
x = 2(f(x) - 10)
x = 2f(x) - 20
Now, simply switch f(x) with x and x with h(x), like so:
h(x) = 2x - 20

the answer is 20

James is buying a motorcycle that costs $2,034.24, including tax. He will pay for it in equal monthly payments over 24 months. How much will James pay each month?
Answer:
$84.76/month
Step-by-step explanation:
We need only determine (calculate) how much the monthly payments are. We use the given information ($2,034.24/month) and the total length of time (24 months) to determine the monthly payment:
$2,034.24
---------------- = $84.76/month
24 months
The amount of money James pays each month is $84.76.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, James is buying a motorcycle that costs $2,034.24, including tax.
Here, monthly payment = Total money/Number of months
= 2,034.24/24
= $84.76
Therefore, the amount of money James pays each month is $84.76.
