Answer:

Step-by-step explanation:

-2

Apply this particular rule of logs:

log a - log b = log a/b

Therefore, log2 (3) - log2 (12) = log2 (3/12) = log2 (1/4)

This last result simplifies to  log2 1 - log2 4 = 0 - 2 = -2

Answer:

-2

Step-by-step explanation:

10 · 3

hi

You are making  f ° h  

f(x) = 9x-5

h(x) = 2x²  

You must first calculate   h(-5)   :     so remplace  x  by -5 in h :

h(-5) = 2 (-5)² =  2* 25 = 50

then apply  f(x) to result  :   f(50) = 9 *50 -5 = 450 -5 = 445  

Answer:

y=3x-3

Step-by-step explanation:

the y(intercept)= -3 because the point is at -3 on the y-axis. from there the line goes up 3 and over 1. the slope would be 3.

All together the equation of the line is:

Y=3x-3

Answer:

100°

Step-by-step explanation:

(20x)° = (7x + 5)° + 60°

20x - 7x = 65

13x = 65

x = 5

m∠BTU = (20 × 5)° = 100°

Answer:

The relation is 'a function that is one-to-many'.

Step-by-step explanation:

From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.

In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.

Therefore, the relation is 'a function that is one-to-many'.

The statements that best describe the relation shown in Item 1 is one to many. Option C is correct

Functions are represented as mappings to relate the domain of the given function with the co-domain.

For instance, the function y= x + b has a domain of x and the codomain of "y"

Mappings can be one to one, where each value of the domain is a unique value in the co-domain

Many to one where one element in the domain have more than one element in the codomain

From the given table, we can see that when y = 10, the corresponding x values are 5 and -5. his shows that the codomain value (10) has more than one unique value in the domain.

Hence the statements that best describe the relation shown in Item 1 is a one to many

Answer:

The equation to find the number did cupcakes bought in all =

= 3c + 7c

= c(3 + 7)

The total number Betty bought in all = 240 cupcakes.

Step-by-step explanation:

Let the amount of cupcakes in a package be represented by c

Betty bought 3 packages of chocolate cupcakes and 7 packages of vanilla cupcakes.

The equation to find the number did cupcakes bought in all =

3 × c + 7 × c

= 3c + 7c

= c(3 + 7)

Each package contains 24 cupcakes

The total number = 3(24) + 7(24)

= 240 cupcakes.

Answer:

112 stamps

Step-by-step explanation:

Shaquille and Amanda's stamps are described in terms of Lyle's, so:

Lyle's = 6x                     6x+3x+2x=364

Shaquille's = 3x                       13x=364

Amanda's = 4x                            x=28

Lyle has 168 stamps, Shaquille has 84, and Amanda has 112. 168+84+112=364

Step-by-step explanation:

2x+x=.3+.8

3x= 1.1/:3

x=0.366

Answer:

x = -2.566667

Step-by-step explanation:

simplify both sides

8 + 2x = 0.3 - x

8 + 2x = 0.3 + - x

2x + 8 = - x + 0.3

add x to both sides

2x + 8 + x = - x + 0.3 + x

3x + 8 = 0.3

subtract 8 from both sides

3x  + 8 - 8 = 0.3 - 8

3x = -7.7

divie both sides by 3

3x/3 = -7.7/3

x = -2.566667
