Answer:
x = - 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4 ← equating to 0
x² + 4x + 4 = 0 ← in standard form
(x + 2)² = 0 ← in factored form, thus
x + 2 = 0 ⇒ x = - 2
Buying shares in a company is one way to invest money.
This statement is true.
When you buy a share in a company, you are investing your money, and you may earn more money if the share’s value rises, or you may lose money if the share’s value falls.
Investing in a company by buying shares makes you a shareholder, with potential income from dividends and stock appreciation. However, it carries risk as there is no guarantee for profits. Diversification is a key strategy when investing in stocks to mitigate risks.
Buying shares in a company is a common method of investment, wherein you become a shareholder and own a part of the company's equity. As a shareholder, you have a claim to the company's assets and profits proportional to the amount of stock you own. There are two primary ways that shareholders can earn money from their investments. One way is through dividends, which are payments distributed from the company's profit to shareholders. The other way is through appreciation in the stock's value, as the company grows and becomes more profitable; this increases the stock's market price, and you can sell your shares for a profit. It's important to understand that purchasing stock does involve risk, as there is no guarantee of dividends or stock appreciation. However, for many, owning stock is preferred over other investments like bonds because of the potential for higher returns. Lastly, when buying stock, especially that of your employer, it's advisable to follow general rules of portfolio investing, such as diversification, not to expose yourself to undue risk.

Answer:
x⁸y³
Step-by-step explanation:
x⁵ ÷ y² × x³ × y⁵
It will be easier to solve this problem if you first rearrange the expression to associate like terms.
(x⁵ × x³) × (y⁵ ÷ y²)
Now, you can use the rules of exponents: When multiplying, you add exponents; when dividing, you subtract exponents.
x⁵ × x³ = x⁵⁺³ = x⁸
y⁵ ÷ y² = y⁵⁻² = y³
Thus,
(x⁵ × x³) × (y⁵ ÷ y²) = x⁸y³

Which function represents g(x), a reflection of f(x) = (3)x across the y-axis?
g(x) = 2(3)x
g(x) = −(3)x
g(x) = (3)−x
g(x) = 2(3)−
Answer: [tex]g(x)=(3)^{-x}[/tex]
Step-by-step explanation:
We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.
i.e. the function [tex]f(x)[/tex] will become [tex]f(-x)[/tex] .
Now, the given function :[tex]f(x)=(3)^x[/tex]
Then , after reflection across y axis the new function will become:
[tex]g(x)=f(-x)=(3)^{-x}[/tex]

Three boys and four girls enter a contest at the local movie theater. A randomly chosen winner will be awarded a free movie ticket, a collectible poster, or free popcorn. What is the probability that a girl will win free popcorn?
Answer:
4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
[tex]\frac{4}{7} * \frac{1}{3} = \frac{4}{21}[/tex]
Answer:
4/21
Step-by-step explanation:
Find the 29th term of the following sequence. 2, 13, 24, 35,....
321
Look for a pattern: The term is 11 more than the number before. this means 11 is added each time.
Since you start with 2 and the number goes up by 11 per term, the equation you would use to find the nth term would be 11n+2
To find the 29th term, simply plug in 29
11n+2
11(29)+2
321
The 29th term is 321.
First you have to find the rate of change. It would be 11 because 35 - 24 = 11, 24 - 13 = 11 and 13 - 2 = 11.
These are the first 4 terms so just keep adding on 11 until you get 29 terms.
2, 13, 24, 35, 46, 57, 68, 79, 90, 101, 112, 123, 134, 145, 156, 167, 178, 189
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
200, 211, 222, 233, 244, 255, 266, 277, 288, 299, 310
19 20 21 22 23 24 25 26 27 28 29
Your final answer would be 310.

What is the solution to the equations of lines A and B?
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.
Answer:
The solution is the point (3,5)
The graph in the attached figure
Step-by-step explanation:
step 1
Line A ----> (2,6),(6,2)
Find the equation of the line A
Find the slope
m=(2-6)/(6-2)
m=-1
Find the equation of the line into point slope form
The equation is equal to
y-y1=m(x-x1)
we have
m=-1
point (2,6)
substitute
y-6=-1(x-2)
y=-x+2+6
y=-x+8 ------> equation of the line A
step 2
Line B ----> (0,3),(4.5,6)
Find the equation of the line B
Find the slope
m=(6-3)/(4.5-0)
m=(2/3)
Find the equation of the line into point slope form
The equation is equal to
y-y1=m(x-x1)
we have
m=(2/3)
point (0,3)
substitute
y-3=(2/3)(x-0)
y=(2/3)x+3 ------> equation of the line B
step 3
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both lines
The solution is the point (3,5)

Answer:
392 ft²
Step-by-step explanation:
Break this area into two parts, that is, into two trapezoids. The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².
The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft). The area of this part is 164 ft².
Thus, the total area is 164 ft² + 228 ft², or 392 ft²

Let f(x)=x^2−10x−11 .
Enter the x-intercepts of the quadratic function in the boxes.
ANSWER
The y-intercept is (0,-11)
The x-intercepts are:
(-1,0) and (11,0)
EXPLANATION
The given function is
[tex]f(x) = {x}^{2} - 10x - 11[/tex]
To find the y-intercept, we put x=0 into the function.
[tex]f(0) = {0}^{2} - 10(0) - 11[/tex]
[tex]f(0) = - 11[/tex]
The y-intercept is (0,-11)
To find the x-intercepts, we put f(x)=0.
[tex]{x}^{2} - 10x - 11 = 0[/tex]
[tex](x + 1)(x - 11) = 0[/tex]
This implies that,
[tex]x = - 1 \: or \: x = 11[/tex]
The x-intercepts are:
(-1,0) and (11,0)

If x= -3 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the equation?
A) The discriminant is negative.
B) The discriminant is -3.
C) The discriminant is 0.
D) The discriminant is positive.
Answer:
C) The discriminant is 0.

1. Victoria is opening a pet store. She will start by making custom dog collars. If the collar cost her $3 each, the embellishments $2, and $0.15 per bag, what is her unit cost per collar?
Answer:
$5.15
Step-by-step explanation:
A dog collar usually consists of a base(collar), the embellishments and the bag in which it is packed.
As we are given,
Collar Price = c = $3
Embellishment price = e = $2
and
Bag price = b =$0.15
The cost of one collar will be the cost of all these combined.
So,
Cost of collar = c+e+b
=3+2+0.15
=5.15
So the price of one collar is $5.15 ..
Answer:
5.15

how much interest is earned on a principal of $575 invested at an interest rate of 7% compounded annually for nine years?
Answer:
$482.11 in interest
Step-by-step explanation:
Use the compound amount formula. Calculate the compound amount and then subtract the principle to find the amount of interest earned.
A = P(1 + r)^t, where r is the interest rate as a decimal fraction
This becomes:
A = $575(1 + 0.07)^9, or A = $1057.11.
Subtracting the principal: A - P: $1057.11 - $575 = $402.11
The total interest earned is $482 on a principal of $575 invested at an interest rate of 7% compounded annually for nine years
What is compound interest?Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
We know the formula for compound interest is,
A = P(1 + r/100)ⁿ.
Where, A = amount, P = principle, r = rate, and n = time in years.
Given, P = $575, n = 9 and r = 7%.
∴ A = 575(1 + 7/100)⁹.
A = 575(1.07)⁹.
A = 575(1.84).
A = 1057.
So, Interest earned is (A - P) = (1057 - 575) = $482.
