Step-by-step explanation:
Which function has a domain where x + 3 and a range where y2?
O fx)=
(x-5)
(x+3)
2(x+5)
O fx)=
(x+3)
O fx)=
2(x+5)
(x-3)
ORX)=(x-3)
(x+5)
Answer:
the second choice or B would be the answer
The function that has a domain where x ≠ 3 and a range where y ≠ 2 are:
f(x) = 2 (x + 5) / (x - 3)
f(x) = 2 (x + 5) / (x - 3)
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The domain of a function consists of all the possible values of x for which the function is defined, and the range of a function consists of all the possible values of y that the function can take.
Now,
f(x) = 2 (x + 5) / (x - 3)
The denominator x - 3 cannot be equal to zero, so x cannot be equal to 3.
Therefore,
The domain of the function is all real numbers except x = 3,
or (-∞, 3) U (3, ∞).
To find the range, we need to consider what values of y the function can take for different values of x.
As x approaches 3 from either side, the value of the function becomes increasingly large (positive infinity for x approaching 3 from the right, and negative infinity for x approaching 3 from the left).
This means that the function has a vertical asymptote at x = 3, and the range of the function is all real numbers except y = 2, or (-∞, 2) U (2, ∞).
And,
f(x) = 2 (x + 5) / (x - 3)
The only value of x that makes the denominator x - 3 equal to zero is x = 3. Therefore,
The domain of the function is all real numbers except x = 3, or
(-∞, 3) U (3, ∞).
To find the range, we again consider what values of y the function can take for different values of x.
As x approaches 3 from either side, the value of the function approaches positive or negative infinity (depending on the sign of x - 3).
This means that the function has a vertical asymptote at x = 3, and the range of the function is all real numbers except y = 2, or (-∞, 2) U (2, ∞).
Therefore,
Both functions have the same domain and range, and both satisfy the conditions of having a domain where x is not equal to 3 and a range where y is not equal to 2.

A package of mixed lettuce seeds contains 150 green lettuce seeds and 50 red lettuce seeds. What is the probability that a randomly selected seed will be a red lettuce seed? Write your answer as a percent.
Answer:
25%
Step-by-step explanation:
I used relative frequency approach
n(total number of seeds)= 150+50=200.
probability (selecting a red lettuce) = red lettuce divided by the total number of seeds.
probability (selecting red lettuce) = 50/200 = 0.25
in percentage, probability = 0.25*100= 25%✓

pls help its due tonight <3
and explain by step pls
Answer:
Step-by-step explanation:
the subtraction symbol means that you will be finding the difference
6x^4-10x^4
the exponents will stay as they are because they are the same
you just have to combine the like terms 6x^4 and 10x^4
a term is separated by a symbol (in this case it is a subtraction symbol)
6x-10x=-4x
so you will just put the exponent back in place and your answer will be
-4x^4

Which of the following is a solution to 3x^2 = 36?
Answer:
x = √12
Step-by-step explanation:
Easy:
3x^2 = 36
Cancel out the 3 so it is only x^2; you can do this by dividing each side by 3 which gives you:
x^2 = 12
Square root the entire thing to get rid of the square and you get the answer
x = √12
richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answer:
His gross pay for the month is $4,509.50
Step-by-step explanation:
The commission Richard Klein earns for oil change = 3.00%
The commission he earns for tune ups = 5.00%
The commission he earns for auto parts sales = 6.25%
The minimum salary he is guaranteed = $2,450.00
The amount he brought in last month includes;
1) $2,500.00 in oil changes
2) $4,500 in tune ups
3) Sold $28,200.00 in parts
The amount he earns last month in commission are;
3/100 × 2,500 = 75 in oil changes
5/100 × 4,500 = 225 in tune ups
6.25/100 × 28,200 = 1762.5 in parts sold
The total commission = 72 + 225 + 1762.5 = 2,059.5
∴ The total commission = $2,059.5
The amount he makes as salary = $2,450.00
Richard Klein's gross pay for the month = His total pay for the month
Therefore;
Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

Answer:
Option A is your answer ☺️
Answer:
x = 5
Step-by-step explanation:
Laws of indices states that if the base is same the power can be added or subtracted. Since this is division, the powers are subtracted.
So, 2x - 3 = 7
or, 2x = 7 + 3
or, 2x = 10
or, x = 10/2
or, x = 5
