Answer:
C
Step-by-step explanation:
When we subtract 9 from both sides we get
[tex]|x|\leq -2[/tex].
Now when we get rid of the absolute value sign, we make two inequalities.
This first is [tex]x\leq -2[/tex] and for the second we need to switch the negative sign to a positive sign and flip the [tex]\leq[/tex] to a [tex]\geq[/tex]. This makes the second equation [tex]x\geq 2[/tex].
P.S. The second equation wasn't an option in the answer.

Answer:
Upper left is 9, upper right is 9, lower left is 21
Step-by-step explanation:
They tell us there are 9 birds that are yes fly and yes fish, so that’s the upper right.
They tell us there are 18 yes fish total. Subtract the 9 from the upper right, and that leaves 9 for the upper left.
They tell us there are 39 birds total.
39 - 18 (all fish eaters) - 4 (no fly, no fish) = 17 that can fly but don’t eat fish.

Answers
Answer:
a-1. The predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. The predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. The predicted price (in $1,000s) of a house without ocean views and square footage of 2,000 is $358,900.
b-2. The predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. The correct option is An ocean view increases the value of a house by approximately $52,600.
Step-by-step explanation:
Given:
yˆ = 118.90 + 0.12x + 52.60d ………………. (1)
a-1. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 1) = 411.50
Since the predicted price is in $1,000s, we have:
yˆ = 411.50 * $1000
yˆ = $411,500.00
Therefore, the predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 1) = 531.50
Since the predicted price is in $1,000s, we have:
yˆ = 531.50 * $1000
yˆ = $531,500.00
Therefore, the predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 0) = 358.90
Since the predicted price is in $1,000s, we have:
yˆ = 358.90 * $1000
yˆ = $358,900.00
Therefore, the predicted price of a house without ocean views and square footage of 2,000 is $358,900.00.
b-2. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 0) = 478.90
Since the predicted price is in $1,000s, we have:
yˆ = 478.90 * $1000
yˆ = $478,900.00
Therefore, the predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. Discuss the impact of ocean views on the house price.
Since the coefficient of d in equation (1) is 52.60 and positive, and the predicted price is in $1,000s; the correct option is An ocean view increases the value of a house by approximately $52,600.
37. The sum of two numbers is 86. The larger number is nine less than four times the smaller number. Find both numbers.
Answers
The larger number is 67 while the smaller number will be 19 for the given condition.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given,
Suppose the larger number is x while the smaller number is y.
Sum will be as x + y = 86
The larger number is nine less than four times the smaller number.
x = 4y - 9
By substitution,
4y - 9 + y = 86
5y = 95
y = 19
x = 86 - 19 = 67
Hence "For the specified condition, the greater number is 67 and the smaller number is 19".

What is the volume of a sphere with a surface area of 16pi ft^2?
Answers
Answer:
B
Step-by-step explanation:
Sphere Surface Area = 4 • π • r²
For it to equal 16 PI, then radius must equal 2
4*PI*2*2 = 16 PI
Sphere Volume = 4/3 • π • r³
Sphere Volume = 4/3 • π • 2^3
Sphere Volume = 4/3 *PI * 8
Sphere Volume = 32 / 3 PI
Sphere Volume = 10.666 PI cubic feet AND I think that is answer B
which SHOULD read 10 (2/3) PI ft^3
179=-9x+8

Answers
Answer:
x = -19
Step-by-step explanation:
first isolate x by subtracting 8 on both sides:
179 = -9x + 8
-8 -8
=> 171 = -9x
then divide -9 on both sides to solve for x:
=> x = 171 ÷ -9 = -19

Solution
-6i^2+5i+4
Answer:
-2 + 5i
Step-by-step explanation:
Remember these rules:
real times real = real (e. g., 4(1) = 4)
real times imaginary: imaginary (e. g., 4(2i) = 8i)
imaginary times real imaginary
imaginary times imaginary: real with a negative sign (e. g., (-3i)(2i) = +6
Once again: work out (-3i)(2i). We get (i^2)(-6) = +6
In summary: your (4-3i)(1+2i) becomes 4 + 8i - 3i - (i^2)(-6), or
4 + 5i - 6, or -2 + 5i

Reason 2)The transitive property of congruenceStep-by-step explanation:
There are several sort of "obvious" properties of equality/congruence. Keeping them sorted out can be a bit of a trick.
A = A . . . . reflexive property
A = B ⇔ B = A . . . . symmetric property (erroneously cited in the proof)
A = B, B = C ⇒ A = C . . . . transitive property (the one needed in the proof)
__
Not to confuse the issue, but there is also the "substitution property of equality" that says if X = Y, then X can be substituted for Y or vice versa. In the end, the transitive property is an application of this, where we're substituting for B in the second equation, or for A in the first equation.
The A=B=C form of Statement 1) in the proof is what gives you the clue it is the transitive property that is wanted here.

We need to rewrite it in the form of [tex]A^x[/tex].
We know that, [tex](\dfrac{1}{x})^{-a}=x^a[/tex]
So,
[tex](\dfrac{32}{5})^{-2x}=(\dfrac{5}{32})^{2x}\\\\=(\dfrac{5^2}{32^2})^x\\\\=(\dfrac{25}{1024})^x[/tex]
So, [tex]A=\dfrac{25}{1024}[/tex]. Hence, this is the required solution.
