Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more.
Dario and another person scuba diving. The other person is diving at negative thirty feet.
A number line from negative fifty to fifty by tens is shown.
After the descent, what was his elevation in relation to another diver at an elevation of −30 feet?
They start at -20 and descend so subtract the amount they descend from the starting value:
-20 -29 = -40
Dario is now at -40 feet.
The other diver is at -30 feet so Dario is 10 feet below Dario.

Answer:
2.44
Explanation:
The number of 6.1% of 40 is 2.44.

I did synthetic division on the righthand side to make sure the answer was correct. Hope this helps :)
Answer:
[tex]\displaystyle x - 10[/tex]
Step-by-step explanation:
Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:
−1| 1 −9 10
↓ −1 10
________
1 −10 0 [tex]\displaystyle \hookrightarrow x - 10[/tex]
You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² - 9x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient will be an [tex]\displaystyle x,[/tex]then you end it off with [tex]\displaystyle 10,[/tex]giving you the quotient of [tex]\displaystyle x - 10.[/tex]

Answer:
[tex]x = 3, x = -12[/tex]
Step-by-step explanation:
Hello!
We can factor the quadratic by grouping. We have to find two numbers that add up to 9 but multiply to -36.
The two numbers are 12 and -3. Expand 9x to 12 x and -3x.
Factor by Grouping[tex]x^2 + 9x - 36 = 0[/tex][tex]x^2 +12x - 3x -36 = 0[/tex][tex]x(x + 12) - 3(x + 12) = 0[/tex][tex](x - 3)(x + 12) = 0[/tex][tex]x = 3, x = -12[/tex]The answer is Option B. x = 3 or -12.

Find the area of the figure.
Find the slope of the line.
Answer:
1
Step-by-step explanation:
it can't be 2 because a slope is always in the mid or after a starting point I think..
Hello there! (:
To find the slope of this graph, we must calculate the rise over the run.
The rise is the amount of units we move up or down; the run is the amount of units we move right or left.
So here, we move 2 units up and 4 units to the right:
[tex]\frac{2}{4}[/tex]
We can reduce our fraction (divide the top and bottom by 2):
[tex]\frac{1}{2}[/tex]

Explicación: Solo puede factorizar, o simplificar, una ecuación o solo variables, si la variable que tiene un exponente tiene la misma base que otra variable, como x ^ 2 y x ^ 3, puede simplificarla ax ^ 5. Ahora, en este problema tenemos un 3, y 2 ^ 2, en el 2 ^ 2, 2 es la base y el otro número es 3, que definitivamente no es la misma base, por lo que no puede factorizarlo más, y deje la variable a lo largo.

10. Nine more than three times a number is -6._
a
Answer:
3n + 9 = -6
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the number = x
3x + 9 = 2x - 6 Looks like you are going to get something negative here.
Subtract 2x from both sides.
3x - 2x + 9 = 2x - 2x - 6
x + 9 = -6
Subtract 9 from both sides.
x + 9 - 9 = - 6 - 9
Combine
x = - 15

jessica saves quarters and dimes in a jar.She uses the expression 0.25q+0.1d to find the value of the coins the variable q is the number of quarters and the d is the number of dimes.Find the value of the coins when jessica has 18 quarters and 15 dimes.Show your work
Answer:
$6.00
Step-by-step explanation:
Total amount of money = 0.25q + 0.1d
where q is the number of quarters and d is the number of dimes
The problem states we have 18 quarters: d = 18
And that there are 15 dimes: d = 15
Plugging it in we get
= 0.25(18) + 0.1(15)
= 4.5 + 1.5
= 6.0

how to solve: -4(2x - 5) = 3x -13
~one variable linear equation
==============================
-4(2x - 5) = 3x - 13
= -8x + 20 = 3x - 13
= -8x + 20 - 3x = -13
= -8x - 3x = -13 - 20
= -11x = -13 - 20
= -11x = -33
= x = -33 ÷ -11
= x = 3 ✔️

What does 4+24÷-6×2=
Answer:
-2, as the expression is written
Step-by-step explanation:
It depends on how one interprets the expression. The expression, as written, is:
4+24÷-6×2=
A fundamental rule in math is known as PEMDAS. This acronym describes the order of operations that are to be followed when solving mathematical expressions. PEMDAS stands for
P- Parentheses,
E- Exponents,
M- Multiplication,
D- Division,
A- Addition, and
S- Subtraction.
The use of parentheses is critical in math expressions, as we will see here.
The are no parentheses in "4+24÷-6×2=." So we will follow the steps are shown above:
Multiplication: 4+24÷-6×2 = 4+24÷-12
Division: 4+24÷-12 = 4+-2
Addition: 4+-2 = 2
The expression as written is equal to 2.
But if parentheses were included in the origianl proble, the answer might be different. For example:
(4+24)÷-6×2=
Parentheses: (4+24)÷-6×2= (28)÷-6×2=
Multiplication: (28)÷-6×2= (28)/-12
Division: (28)/-12 = -2.333 . . .

f f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x))? On a coordinate plane, a straight line has a positive slope and goes through (negative 2, negative 1), (0, 0), and (4, 2). On a coordinate plane, a straight line has a positive slope and goes through (negative 3, negative 3), (0, 0), and (3, 3). On a coordinate plane, a straight line has a negative slope and goes through (negative 4, 2), (0, 0), and (4, negative 2). On a coordinate plane, a straight line has a negative slope and goes through (negative 3, 3), (0, 0), (3, negative 3).
Using inverse function concepts, it is found that the graph of f(g(x)) is given as follows:
On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).
What happens when two inverse functions are composed?When two functions f(x) and g(x), that are inverse of one another, are composed, that is, y = f(g(x)), the resulting function is given by:
y = x.
Hence the graph of f(g(x)) is given as follows:
On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).
