The number of bags of popcorn = 6

The number of pretzels  = 4

Let the number of bags of popcorn = x

the number of pretzels = y

From the question, we have

she bought $60 worth of bags of popcorn and pretzels.

Each bag of popcorn costs $7.50 and each pretzel costs $3.75.

7.50x+3.75y = 60................(i)

She bought 2 more bags of popcorn than pretzels.

x-y = 2................(ii)

Solving equation (i) and (ii), we get

x = 6

y = 4

The number of bags of popcorn = 6

The the number of pretzels  = 4

Addition:

The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition. One-digit numbers can be added simply for solving addition problems, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on.

Answer:

x = 1/2

y = 4

Step-by-step explanation:

2x + 3y = 13 ----------------------(1)

4x - y = -2  ------------------------(2)

Multiply Eq. (1) by 2

2(2x + 3y) = 13 × 2

4x + 6y = 26 -------------------(3)

Subtract Eq. (3) from Eq. (2)

4x - y - 4x - 6y = -2 - 26

-y - 6y = -28

-7y = -28

7y = 28

Divide 7 to both sides

Put y = 4 in Eq. (2)

4x - 4 = -2

Add 4 to both sides

4x = -2 + 4

4x = 2

Divide 4 to both sides

x = 2/4

We will see that the functions are inverses by proving that the composition is equal to the identity.

Two functions are inverses if their composition is equal to the identity, this means that if h(t) and k(t) are inverses, then we can write:

h(k(t)) = t

and

k(h(t)) = t

Proving one of these will be enough.

Here the functions are:

h(t) = (3t + 5)/t

k(t) = 5/(t - 3)

Let's find h(k(t))

We will get:

h(k(t)) = (3*k(t) + 5)/k(t)

Now we can replace the function k(t) there.

h(k(t)) = (3*5/(t - 3) + 5)/(5/(t - 3))

Now we can simplify this using algebra.

h(k(t)) = ( 15/(t - 3) + 5)*(t - 3)/5

h(k(t)) = (15/(t - 3))*(t - 3)/5 + 5*(t - 3)/5

h(k(t)) = 3 + (t - 3) = t

h(k(t)) = t

So yes, the two functions are inverses.

Step-by-step explanation:

f(x) = |x|

This absolute value will have a v shape, the "v" point at (0,0)

Next,

f(x) = |x-1|

This (-1) moves the v shape one unit to the right, "a translation to the right by 1."

Finally,

f(x) = |x-1| - 3

This (-3) moves the v shape down 3 units. This is why the answer is the original

f(x) = |x|

except it's moved right by 1, and down by 3.

Step-by-step explanation:

The graph that represents is translated right by 1 units and 3 unit up to form. Hence, graph (a) is correct.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

The parent function of an absolute function is;

y = |x|

When a function is translated right by h units, the transformation rule by;

y = |x-h|

So:

|x-1|-3 means that it is translated right by 1 units

When a function is translated up k units, then the transformation rule is:

y = |x| + k

y = |x-1|-3

This means that it is translated right by 1 units and 3 unit up to form

Hence, graph (a) is correct

Step-by-step explanation:

The number of men and women that work at the company are;

Number of men = 36

Number of women = 18

Let the total number of employees in the company be x.

Now, we are told that 75% of the employees were men. Thus;

Number of men = 75% * x = 0.75x

Number of women = 0.25x

Now, we are told that after 6 women joined, the ratio of men to women became 2: 1.

Thus;

New total employees = x + 6

New total number of women = 0.25x + 6

Thus;

0.75x/(0.25x + 6) = 2/1

Cross multiply to get;

0.75x = 2(0.25x + 6)

0.75x = 0.5x + 12

0.75x - 0.5x = 12

0.25x = 12

x = 12/0.25

x = 48

Number of women = 0.25(48) + 6 = 18

Number of men = (48 + 6) - 18 = 36
