Answer:
y = 19/4
Step-by-step explanation:
replace x by 2
then 10 × 2 = 20
switch the 20 to the other side and subtract 20 from 1
it will be -19
and -4 will go to the other side as a divide and -
z
-19 / -4 = 19/4
evaluate the function when x = -3

The sum of two numbers is __________ greater than either number.
a) Always
b) Sometimes
c) Never
d) Not enough information
The correct answer is b) Sometimes.
Given that a statement,
"The sum of two numbers is __________ greater than either number."
We need to fill the blank from the options provided.
The sum of two numbers can be greater than either number depending on the specific values of the numbers.
Let's consider some examples:
Example 1: If we have two positive numbers, such as 3 and 4, their sum (3 + 4 = 7) is greater than either number individually.
Example 2: If we have one positive number and one negative number, such as 5 and -8, their sum (5 + (-8) = -3) is greater than -8 but less than 5.
Example 3: However, if we have two negative numbers, such as -2 and -4, their sum (-2 + (-4) = -6) is not greater than either number individually.
Therefore, since the statement holds true in some cases but not in others, the correct answer is sometimes (b).

Step-by-step explanation:
The value of a boat is $23,400. It loses 10% of its value every year. Find the approximate monthly percent decrease in value. Round your answer to the nearest hundredth of a percent.
Answer:
Value of boat = $23,400
Loss of value by boat per year = 8%
To find: - Monthly percent decrease in value of boat.
Solution: - Decrease of value per year = 8% of $23,400 = $1,872. Monthly decrease in value = $1,872/12 = $156. Monthly percentage decrease = ($156/$23,400) * 100 = 0.6667 or 0.67 (rounded to nearest hundredth)

C) 8
B) 10
D) 2
Answer:
B) 10
Step-by-step explanation:
Exterior angle property: Exterior angle equals the sum of opposite interior angles.
12x + 10 = -10 + 7x + 70 {Subtract 10 from both sides}
12x = -10 + 7x + 70 - 10
12x = -10 + 70 - 10 + 7x {Combine like terms}
12x = 50 + 7x {Subtract 7x from both sides}
12x - 7x = 50
5x = 50 {Divide both sides by 5}
x = 50/5
x = 10

A.x=k(y-h)-g
B.x=ky -h+g
C.x=k(y-h) +9
D.x = ky-h-9
Answer:
a
Step-by-step explanation:
The equation equivalent to the given equation y-h=x-g/k is .x=k(y-h) +g. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is y-h=x-g/k. The equation will be solved as,
y-h = ( x-g ) / k
k( y-h ) = x - g
k( y-h ) + g = x
Therefore, the equation equivalent to the given equation y-h=x-g/k is .x=k(y-h) +g. The correct option is C.

© The mean temperature for the first 4 days in January was -4°C.
The mean temperature for the first 5 days in January was -6°C.
What was the temperature on the 5th day?
Answer: The temperature on the fifth day is -14°C
Step-by-step explanation:
When we have a set of N elements, that can be written as:
{a₁, a₂, ..., aₙ}
The mean of these N elements is be written as:
Mₙ = (a₁ + a₂ + ... + aₙ)/N
Now, when we take in account the temperature for the first four days of January, we will have a set of 4 elements, {a₁, a₂, a₃, a₄}
Where each one of these elements represents the temperature of one particular day.
The mean temperature for the first four days will be:
M₄ = (a₁ + a₂ + a₃ + a₄)/4
And we know that this is equal to 4°C
Now we also could do the next replacement:
(a₁ + a₂ + a₃ + a₄) = T
Then we can write:
M₄ = -4°C = (a₁ + a₂ + a₃ + a₄)/4 = T/4
Then we can solve:
-4°C = T/4
-4°C*4 = T
-16°C = T
This is the sum of the temperatures for the first four days of January.
Now we know that the mean for the first five days is -6°C
Then we have:
M₅ = (a₁ + a₂ + a₃ + a₄ + a₅)/5 = -6°C
Where a₅ is the temperature on the fifth day of January, which is the value we want to find.
And we know that:
a₁ + a₂ + a₃ + a₄ = -16°C
We can replace that in the equation to get:
(-16°C + a₅)/5 = -6°C
(-16°C + a₅) = 5*(-6°C) = -30°C
a₅ = -30°C + 16°C = -14°C
a₅ = -14°C
The temperature on the fifth day is -14°C

the location of the light bulb
the bottom of the lampshade
the top of the lampshade
a vertex of the shadow
Answer:
A THE LOCATION OF THE LIGHT BULB
I got this right on the assignment
Step-by-step explanation:
The centre of the hyperbola represent will represent the location of the light bulb.
What is the centre of a hyperbola?The centre of a hyperbola is the midpoint of the line segment joining its foci. The transverse axis is the line segment that contains the centre of the hyperbola and whose endpoints are the two vertices of the hyperbola.
As we know that the centre of a hyperbola is the midpoint of the line segment joining its foci. Now, if we plot the hyperbola with equation
[tex]\dfrac{(y-3)^2}{2}-\dfrac{x^2}{1}=1[/tex]
The hyperbola will look like the one given in the below image, further if draw two lines to know the centre of the hyperbola, we will find that the centre of the hyperbola will lie at coordinate (0,3).
Further, the centre of the hyperbola represents the light bulb while the hyperbolas will represent the shadow cast by the lampshade.
Hence, the centre of the hyperbola represent will represent the location of the light bulb.

Answer:
189/230
Step-by-step explanation:
Convert these to fractions first, because then it would be easier to calculate.
3 39/50 divided by 4 3/5
Turn the fractions into improper fractions:
189/50 divided by 23/5 = 189/50 times the reciprocal of 23/5
So we have:
189/50 x 5/23 = 945/1150 = 189/230
