Identify the constant term in this expression.
8x + 4y + xy + 1
Please help
The like terms are the terms that can be put
together. (9x) and (3x) are like terms because
they both have an x attached. (–5) and (3) are
like terms because they have nothing attached.

What is the length of arc S shown below? Enter an exact expression. The angle in the figure is a central angle in radians.
Answer:
h
Step-by-step explanation:
n
Answer:
the answer is 18π/5
Step-by-step explanation:
A Central angle (θ) measured in radians tells us how many times the radius fits into the arc.
arc length ÷ radius = θ
arc length = θ · radius
S = 3π/5 · 6 cm
S = 18π/5 cm
Therefore the answer is 18π/5

Suppose (-7, -3) is reflected across the x-axis, and then the y-axis. what will be the new coordinates?
Answer:
C (7, -3)
Step-by-step explanation:
Reflecting on x causes the x value to change signs, then again on y changes the y value's sign.
Answer:
B
Step-by-step explanation:
-7 is the x and -3 is the y so flip would be (-7,3)
You want to buy a specific computer. A sales representative of the manufacturer claims that retail stores sell this computer at an average price of $1,249 with a very narrow standard deviation of $25. You find a website that has a price comparison for the same computer at a series of stores as follows:
$1,298; $1,229.96; $1,193.07; $1,279; $1,224.98; $1,229.97; $1,269.98; $1,248.
Can you argue that pricing has a larger standard deviation than claimed by the manufacturer?
Answer:
We fail to reject the null
Step-by-step explanation:
Given the data: 1298; 1229.96; 1193.07; 1279; 1224.98; 1229.97; 1269.98; 1248
Mean price, μ = 1249
Standard deviation, σ = 25
Variance, σ² =
Null hypothesis, H0 : σ² = 25²
Alternative hypothesis, H1 : σ² > 25
Using calculator, the sample standard deviation :
Sample standard deviation = s = 34.072
Sample size, n = 8
For chi² distribution :
X² = [(n - 1)s²] ÷ σ²
X² = [(8 - 1)*34.072^2] ÷ 25^2
X² = (7 * 1160.901184) / 625
X² = 13.002093
Using the Pvalue from Chisquare calculator, df = 8 - 1 = 7; α = 0.05
Pvalue =0.07206
0.07206 > 0.05
Since , Pvalue > α
We fail to reject the null; there is insufficient evidence to conclude that standard devuatue do selling a computer is greater than 25

Pls help ASAP PLS PLS PLS
Answer:
Step-by-step explanation:
Let the exponential function for the given table is,
f(x) = a(b)ˣ
Here, f(x) = Price of the item after 'x' years
a = Initial price of the item
b = Growth factor
x = Duration(years) from year 1913
By exponential regression calculator,
Exponential function represented by the table will be,
f(x) = 7.822(1.034)ˣ
Now we have to calculate the price of the item in year 2025.
Difference in time = 2025 - 1913
= 112 years
Price of the item after 112 years,
f(112) = 7.822(1.034)¹¹²
= $330.840
Ally picked 25 roses. She gave away 10 roses. What percent of the roses does Ally still have?
Answer:
She still has 60%
Step-by-step explanation:
First you make the 25 a 100 which is basically multiply by 4 which you should do the same for 10
so 40/100 is how much she game away
She gave away 40%
She still has 60%
The percent of the roses does Ally still have is 60%.
Given that,
Ally picked 25 roses. She gave away 10 roses.
Based on the above information, the calculation is as follows:
[tex]= \frac{25-10}{25}[/tex]
= 60%

Given f(x) = x^2+ 3x, find f(A + 4).
Answer:
f(x) = x^2+ 3x
f(A + 4)=(A+4)²+3(A+4)=A²+8A+16+3A+12
=A²+11A+28
y + 2x = -1
y = 1/2x + 4
Answer:
x = -1
y = 3
Step-by-step explanation:
y + 2x = -1
y = 1/2x + 4
(1/2x + 4) + 2x = -1
1/2x + 2x + 4 = -1
2 1/2x + 4 = -1
2 1/2x = -1 - 4
2 1/2x = -5
x = -5 / 2 1/2
x = -2
y + 2x = -1
y + 2(-2) = -1
y - 4 = -1
y = -1 + 4
y = 3
which one is a Metaphor
1. A phrase where the words have no connection to their meaning. carries no meaning outside of context or prior experience with the phrase and cannot be translated.
2. Extreme exaggeration
3. words that have the same beginning sound together
4. A reference or mention of a person, event, statement, piece of art, history, myths, religion, or popular culture

6. Giving human characteristics to non-human things.
Answer:
5. A metaphor is a direct comparison that does NOT use the words like or as. It says that something is something else.

x-1/x^2 - x - 20 Give the equivalent numerator if the denominator is (X - 5)(x + 4)(x + 3)
x^2 + 2x + 3
x^2 + 2x - 3
x^2-3
Answer:
[tex]x^2+2x-3[/tex]
Step-by-step explanation:
Note that [tex]x^2-x-20=(x-5)(x+4)[/tex], so, if the denominator is [tex](x-5)(x+4)(x+3)[/tex], we need to multiply the numerator by [tex](x+3)[/tex]. And [tex](x-1)(x+3)=x^2+2x-3[/tex].

Fifteen less than twice a number is 21.
What is the missing number? |
Answer:
2y - 15
Step-by-step explanation:
well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.
Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.
now that we have the first half done, we have to take the 15 less. Less can mean or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.
Hello!
First of all, let the number be r.
"twice a number" means we multiply that number by 2:
2r
Subtract 15 (fifteen less)
2r-15
This is equal to 21:
2r-15=21
[tex]\rule{160}{2}[/tex]
Solve the equation:
2r=21+15
2r=36
Divide both sides by 2:
r=18
Hope everything is clear.
Let me know if you have any questions!

#3 (1 pt) A certain baseball card is very rare and is currently worth $2000. If the price of this card increases by 3% a year,
write an exponential equation for how much the card will be worth x years from now.
Answer:
$2000x(1.03)ˣ
Step-by-step explanation:
This is known as compound interest.
100% + 3% = 103%, so we put this into a decimal: 1.03
We now put this into the equation:
$2000x(1.03)ˣ
If you want to work out the price after, say 3 years, then you would change x to 3, so the equation becomes
$2000x(1.03)³
You can then use a calculator to work out the answer.
