If f(x) = 3x + 10x and g(x) = 4x - 2, find (f+ g)(x).
O A. 17x-2
O B. 3* - 6x + 2
O C. 3x + 14x - 2 3X 2
O D. 3X + 6x + 2 +
Step-by-step explanation:
(f + g)(x) is simply f(x) + g(x).
you simply add both expressions :
3x + 10x + 4x -2 = 17x - 2

pls help this is urgent! Graph the Solution to this inequality on the number line!
Answer: A. x <= -3
Step-by-step explanation:
First, let's begin by simplifying the inequality:
-4x >= 12 ← To isolate the x, we need to divide both sides of the inequality by -4 (we must make this change to both sides so that the inequality is still valid). Remember that when dividing an inequality by a negative number, the orientation of the sign switches (greater than → less than, less than → greater then, etc.). So...
-4x / -4 <= 12 / -4 ← Simplify...
x <= -3
Now, we need to find the right number line representing this inequality.
There should be a solid dot over -3, because the inequality includes the value -3 (x includes values less than and equal to -3).The number line should be pointing to the left, towards values less than -3.The number line that fits these criteria would be number line A.
The number line that represents the solution for the inequality -4x ≥ 12 is between the interval (-3 , -∞) .
What is number line?A number line is a representation of real numbers in the form of a graduated straight line. Every point on a number line is assumed to be a real number, and every real number is assumed to be a point. Some will have a defined beginning and end point. These are known as closed number lines. Number lines can also be empty or blank.We now have
-4x ≥ 12
We have to divide both sides by -4
-4x/-4 ≥ 12/-4
x ≤ -3
Keep in mind that less change equals more change.
The interval (-3 , -∞) is the solution.
All real numbers that are lesser than -3
The shaded area to the right of the dashed line represents the solution to the inequality.
Therefore the number line of this solution will be option 1.

Carns Company is considering eliminating its Small Tools Division, which reported a loss for the prior year of $205,000 as shown below. Segment Income (Loss) Sales $ 1,430,000 Variable costs 1,295,000 Contribution margin 135,000 Fixed costs 340,000 Income (loss) $ (205,000) If the Small Tools Division is dropped, all of its variable costs are avoidable, and $119,000 of its fixed costs are avoidable. The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

Two rectangles of the same shape have areas of 676 and 3,457 square centimetres. If the shorter side of the larger rectangle is 41 centimetres, what are the dimensions of the smaller one?
The dimensions of the smaller rectangle are 13 centimeters by 52 centimeters.
Let's assume the dimensions of the smaller rectangle are length L and width W (in centimeters).
We know that the area of the smaller rectangle is 676 square centimeters:
L * W = 676 ----(1)
We also know that the larger rectangle has a shorter side of 41 centimeters. Let's say the corresponding longer side of the larger rectangle is H centimeters.
The area of the larger rectangle is 3457 square centimeters:
41 * H = 3457 ----(2)
Our current set of equations contains two unknowns. In order to get the smaller rectangle's dimensions, we can simultaneously solve these equations.
In order to find H, we can use equation (2):
H = 3457 / 41
H ≈ 84.22
Now we can substitute this value of H into equation (1):
L * W = 676
We need to find the dimensions (L and W) that multiply to give 676. We can start by looking for factors of 676.
Factors of 676: 1, 2, 4, 13, 26, 52, 169, 338, 676
By trial and error, we can see that the factors that give a close match to the dimensions of the larger rectangle (41 and 84.22) are 13 and 52:
L = 13
W = 52
Therefore, the smaller rectangle has measurements of 13 by 52 centimetres.

Factor the GCF out of the following expression
Answer and Step-by-step explanation:
To find the GCF (Greatest Common Factor), you need to see what all of the numbers have in common.
By looking at the terms in the expression, we can see that all the numbers are divisible by 4, so lets factor that out.
\(4(23x^7y^5+24x^5y^4+11x^4y^5)\)
We can also see that the terms have a \(x^4\) and \(y^4\) in common, so factors those out.
\(4x^4y^4(23x^3y+24x+11y)\) <- This is the answer.

The average electric bill for a small electric company is $72 for the month of April with a standard deviation of $6. If the amounts of the bills are normally distributed, find the probability that the mean of the bills for 15 randomly selected residents will be less than $75
Answer:
Hence the probability that the mean of their utility bills will be less than $75 = P(X < 75) is 0.9736.
Step-by-step explanation:
Now,
Population mean electric bill, \(\mu =\) $72
Population standard deviation, \(\sigma =\) $6
Standard error of the mean\(= \sigma / \sqrt{n} = 6 / \sqrt{15} = 1.5492\)
The probability that the mean of their utility bills will be less than $75 = P(X < 75)
= P[Z < (75 - 72) / 1.5492]
= P[Z < 1.9365]
= 0.9736 (Using Z table)
find the height of the building when x = 3m, y = 6m, and d = 6m
Answer:
To find the height of the building, we can use the following formula:
height = y(d-x)/x
Substituting the given values, we get:
height = 6(6-3)/3
height = 6(3)/3
height = 6 meters
Therefore, the height of the building is 6 meters.
If the center of the circle is Point A, what is the difference between the circumference of the circle and the perimeter of the triangle, to the nearest tenth of a unit?
A 20.6 units
B 28.2 units
C 80.7 units
D 95.5 units
The difference between the circumference of the circle and the perimeter of the triangle is 28.2 units. (Option B)
To find the length of each side of triangle, the distance is calculated between the vertices using the formula:
d = √((x2 – x1)^2 + (y2 – y1)^2)
Hence,
AB =√((-4 – 0)^2 + (9 – 0)^2) = 9.85 units
AC = √((9 – 0)^2 + (4 – 0)^2) = 9.85 units
BC = √((9 – (-4))^2 + (4 –9)^2) = 13.93 units
Hence, the perimeter of the triangle = 9.85 + 9.85 + 13.93 = 33.6 units
As AB and AC is the radius of the circle, the circumference of the circle is:
C = 2πr = 2π(9.85) = 61.8 units.
Hence, the difference between the circumference of the circle and the perimeter of the triangle = 61.8 – 33.6 = 28.2 units.
