Answer:
y=3sqrt(x)
x≥0
Step-by-step explanation:
The domain of a function refers to all values of x for which y is defined.
Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.
As soon as the expression under the root sign is less than zero, the function will not be defined.
This means that the square root of a negative number will not be a real number.

Help please.. for my sister .... I’m older and I don’t get this
Answer: C. Point M
Step-by-step explanation:
There are 10 tick marks. The tick marks could be guessed to be 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.50. 1/3 as a decimal is 0.33. The point should be between the(6th tick mark) 0.3 and (7th tick mark) 0.35 based on the assumed tick marks. Looking at the number line, the point that is between the 6th and 7th tick mark is M. Therefore, the answer is Point M.8x-19 = -12x+61 What is x?
Answer:
x is 4
Step-by-step explanation:
Step one: Add 12x to both sides-
8x-19+12x=-12x+61+12x
20x-19=61
Step 2: add 19 to both sides
20x -19+19=61+19
20x=80
Step 3: divide both sides by 20
20x/20=80/20
x=4
In the early spring, the trout at Big Blue Lake swim at a depth of 30 feet below sea level.
When the lake warms up in the summer, the trout swim 20 feet deeper than that.
At what position relative to sea level do the trout swim in the summer?
Given :
In the early spring, the trout at Big Blue Lake swim at a depth of 30 feet below sea level.
When the lake warms up in the summer, the trout swim 20 feet deeper than that , d = 20 feet .
To Find :
At what position relative to sea level do the trout swim in the summer.
Solution :
Depth in spring from surface , [tex]D_s=30\ feet[/tex] .
Let , depth in summer is D .
Now , depth in summer relative to sea-level is :
[tex]D=D_s+d\\\\D=30+20\ feet\\\\D=50\ feet[/tex]
Therefore , trout swim 50 feet deep below the sea level in the summer .
Hence , this is the required solution .

The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8), what are
the coordinates of B?
Answer:
Step-by-step explanation:
(x - 3)/2= 1
x - 3 = 2
x = 5
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
The coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
It is given that:
The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8).
Let the coordinate of B is (x, y)
From the midpoint theorem:
(x - 3)/2= 1
x - 3 = 2
x = 5
For y coordinate:
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
Thus, the coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),

14 + x = -9 What is the answer?
Answer:
The answer is 23 my Dear random friend!
Step-by-step explanation:
:DAnswer:
See Below
Step-by-step explanation:
14 + x = -9
To isolate x, subtract 14 from both sides
14 + x = -9

A plumber charges $17 to visit a client's home, plus an additional $36 per hour. What is the
duration, in hours, of a plumber's visit that costs $89?
Answer:
I believe the duration for $89.00 is 2 hours
Step-by-step explanation:
We start off with the $17 dollars and calculate 36.00+36.00 for a total of $89. Therefore, (120 mins)/60=2 hours.
Because this is a linear problem, I'd use the slope-intercept formula:
[tex]y = mx + b[/tex]
where
m = slope (rise/run)
y = dependent value
x = independent value
b = constant value
Because the plumber charges $17 upon arrival, it is our constant. The $36 is our slope (per hour, per minute, per etc. is generally a give away). Additionally because the total cost of the plumber's visit depends on how long s/he stays at a client's home, the $89 is our y value. Therefore the equation should look like this:
[tex]89 = 36x + 17[/tex]
Solve for x by subtracting 17 from both sides of the equation then dividing by 36.
[tex]72 = 36x[/tex]
[tex]2 = x[/tex]
The plumber spent two hours at his/her client's home.

The expression -120+13m represents a submarine that began at a depth of 120 feet below sea level and ascended at a rate of 13 feet per minute. What was the depth of the submarine after 6 minutes?
Answer: The depth was 42 feet below see level after 6 minutes
Step-by-step explanation:
If m represents the minutes then input 6 for m into the expression and solve.
-120 + 13(6)
-120 + 78 = -42

17. The volleyball club is raising money for a
new net and equipment. They need $842.36 to
purchase the swing set and have received a
$300.00 donation. The remaining amount will
be equally divided among 4 different
fundraisers throughout the summer. How
much money will each fundraiser need to raise
in order to purchase the new net and
equipment?
$2,169.44
$542.36
0 $135.59
O $210.59
The money will each fundraiser need to raise in order to purchase the new net and equipment is $135.59. Therefore, option C is the correct answer.
Given that, the volleyball club need $842.36 to purchase the swing set and have received a $300.00 donation.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the money will each fundraiser need to raise in order to purchase the new net and equipment be x.
Now, the remaining amount = 842.36 - 300.00
= $542.36
The remaining amount will be equally divided among 4 different fundraisers = x = 542.36/4
=135.59
The money will each fundraiser need to raise in order to purchase the new net and equipment is $135.59. Therefore, option C is the correct answer.

whatssssssssssssss divied 3/7 and 2/3
Answer:
9/14
Step-by-step explanation:
3/7÷2/3=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
3/7×3/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
3×3
7×2= 914
This fraction cannot be reduced.
Therefore:
3/7÷2/3=9/14
Answer:
9/14
Step-by-step explanation:
3/7 ÷ 2/3= 9/14
To divide a fraction, you have to flip the second fraction and multiply.
3/7 × 3/2 = 9/14
9/14 is in simplest form.
find the percent increase from 200 to 240
Answer:
20%
Step-by-step explanation:
The percentage change can be found from ...
% change = ((new value)/(reference value) -1) × 100%
= (240/200 -1) × 100%
= 0.20 × 100%
= 20%
240 is an increase of 20% from 200.

Mary Jane is buying paper plates for her big going away party. The fancy plates come in packs of 8. She is inviting 41 guests. How many packs of plates should Mary Jane buy?
41 guests / 8 plates = 5.125 packs
Since you cant buy .125 of a pack, Mary jane has to purchase 6 packs.
Answer:
6 packsStep-by-step explanation:
41 guests = 5.125 packs
8 plates
5 x 8 = 40 plates
6 x 8 = 48 plates
therefore Mary Jane should buy the 6 packs more than enough for her 41 guests.
