Answer: the expression 12f + 24 represents 12 times a quantity, added to 24.

Expplanation.

The expression 12f + 24 is an algebraic expression, especifically a first degree binomial; this is, a polynomial of two terms, whose maximum power is 1.

The algebraic expressions are used to represent word statements in mathematical language.

You can analyze each term of the expression and then tell what the total expresssion represents:

The first term 12f, where f is a variable with degree 1 (the exponent of the variable), represents the multiplication of a quantity (represented by the variable f) by 12.

24 is the constant term, it represents an constand addend.

Hence, the total expression represents the multiplication of a quantity by 12, and, after the multplication is done, added with 24.

The graph of a function f(x)=5to the power of x -5 contains the point (2,y) what is the value of y

Mila [183]

I believe this this the function.

$f(x) = {5}^{x - 5}$

then

$f(x) = {5}^{2 - 5}$

then

$f(x) = {5}^{ - 3}$

then

$y = \frac{1}{125}$

M(2,5) is the midpoint of RS. The coordinates of S are (3,9). What are the coordinates of R?

Solve the system

9x = 27-9y
20x=71-9y

Let's use the "elimination through addition/subtraction method.
Multiply the first equation by -1 so as to obtain +9y:

-9x = -27 + 9y
20x= 71- 9y
--------------------

Add these 2 equations together:

-9x = -27 + 9y
20x= 71- 9y
--------------------
 11x = 44

Solve this for x: x = 44/11 = 4.

Now find y by subst. 4 for x in either of the original equations.

Using the second equation: 

20x=71-9y
20(4) = 71 - 9y
80-71 = -9y
9 = -9y. Then y = -1.

The solution set is (4,-1).

The number of Atlantic blue fin tuna in thousands can be modeled by P(x)=230(.881)^x where X represents the number of years sinc

Maurinko [17]

<h3>Answer: 1981</h3>

===================================

Work Shown:

Recall that P is in thousands, so P = 95 means 95,000.

Plug in P(x) = 95. Solve for x. Use logarithms to get this done.

P(x)=230(0.881)^x

95=230(0.881)^x

95/230 = (0.881)^x

0.41304347826087 = (0.881)^x

(0.881)^x = 0.41304347826087

Log( (0.881)^x )= Log( 0.41304347826087 )

x*Log( 0.881 )= Log( 0.41304347826087 )

x= Log( 0.41304347826087 )/Log( 0.881 )

x= 6.97883817154785

x= 7

Approximately 7 years after 1974 is when the population will be around 95,000.

7 years after 1974 = 1974+7 = 1981

(10.5-7)+(4x3) help please

Leno4ka [110]

Answer: 15.5

Step-by-step explanation:

(10.5-7)+(4x3)

following PEDAS we do operations in parentheses first

10.5-7=3.5

4x3=12

we now have 3.5+12 as our intermediate expression

and 3.5+12 = 15.5
