The resulting expression using the distributive property of multiplication over subtraction is 3(12) - 3(10).

The distributive property of binary operations extends the distributive law, which states that in elementary algebra, equality is always true.

For instance, given the expression;

A(B - C)

We will have to distribute A over B and C to have;

A(B - C) = AB - AC

Applying the rule to the given expression

3 (12 - 10)

3(12) - 3(10)

This shows that the given expression can also be written as 3(12) - 3(10)

Answer

y can take on any real number value except around 1 < y < 3 where none of the graphs have values around this region.

Hence, this is the range of the graph.

Explanation

The range of a function refers to the region of values where the fumction can exist. It refers to the values that the dependent variable [y or f(x)] can take on.

From the graph attached to this question, we can see that the function has different forms at different values of x.

But it is also evident that y can take on any real number value except around

1 < y < 3 where none of the graphs have values around this region.

Hence, this is the range of the graph.

5 quarters, 3 dimes, 7 nickels

Let the number of quarters in the jar = q

Let the number of dimes in the jar = d

Let the number of nickels in the jar = n

1 quarter = $0.25

1 dime = $0.1

1 nickel = $0.05

The jar is filled with quarters, dimes, and nickels, totaling $1.90

This can be represented mathematically as:

0.25q + 0.1d + 0.05n = 1.90.........(1)

There are two more quarters than dime:

q = d + 2..............(2)

There are two more nickels than quarters

n = q + 2..............(3)

make d the subject of the formula in equation (2)

d = q - 2............(4)

Substitute equations (3) and (4) into equation (1)

0.25q + 0.1(q - 2) + 0.05(q + 2) = 1.90

0.25q + 0.1q + 0.05q - 0.2 + 0.1 = 1.90

0.4q - 0.1 = 1.90

0.4q = 1.90 + 0.1

0.4q = 2.0

q = 2.0/0.4

q = 5

n = q + 2

n = 5 + 2

n = 7

d = q - 2

d = 5 - 2

d = 3

There are 5 quarters, 3 dimes, 7 nickels

ANSWERS

(a) 68 ft

(b) 136 ft/s

(c) 128 ft/s

EXPLANATION

(a) The time interval is from 4s to 4.5s, so the distance the ball travels from 4s to 4.5s is,

(b) As stated, the average velocity is the quotient between the distance traveled and the time,

(c) Here we have to find the distance as we did in part b and then divide by the time interval,

As we can see in the middle values, as the time interval is shorter - the difference approaches 0, the value of the velocity is closer to 128ft/s.

Hence, the estimated instantaneous velocity at t = 4 is 128 ft/s

Explanation:

We will find the expression for each space in the following order

To find the first expression, we need to find a number that multiplied by 6 is equal to 18. This number is 3 because

6 · 3 = 18

Then, for the second space, we need to factorize the expression 36x² + 144x + 108 as follows

36x² + 144x + 108 = 8(2x² + 8x + 6)

So, the expression that multiplied to 8 is (36x² + 144x + 108) is (2x² + 8x + 6).

The third space can be calculated by factorizing 2x² + 8x + 6 as

2x² + 8x + 6 = (x + 3)(2x + 2)

Therefore, the expression in the third space is (2x + 2)

Finally, for the fourth and fifth space, we need to multiply the expression to the left, so

6(2x + 2) = 6(2x) + 6(2) = 12x + 12

3(x + 3) = 3(x) + 3(3) = 3x + 9

A linear equation is one that has the form Ax+By=C. This definition comes from mathematics. It consists of two variables combined with a constant value that exists in each of them.

The values of the variables will be obtained when the system of linear equations is solved; this is referred to as the solution of a linear equation.

Given the linear equation y = 2x + 4

If x = -4

y =2(-4) + 4

y = -4

If x = -2

y =2(-2) + 4

y = 0

If x = 0

y =2(0) + 4

y = 4

Step 1: writing the equation

We have a triangle with sides n, 4n - 2, and 4n - 7

We obtain its perimeter if we add all its sides:

n + 4n - 2 + 4n - 7

Since the perimeter is 45 cm, then:

n + 4n - 2 + 4n - 7 = 45

combining like terms:

n + 4n +4n = 9n

and

-2 - 7 = -9

then, we have:

n + 4n - 2 + 4n - 7 = 45

↓

9n - 9 = 45

Step 2: finding n

Now we solve the equation:

9n - 9 = 45

↓ taking -9 to the right

9n - 9 + 9 = 45 + 9

9n = 54

↓ taking 9 to the right

n = 54/9 = 6

Then, n = 6

Step 3: sides measure

Since the measure of the first side is given by n,

then its length is

n = 6

SInce the measure of the second side is given by 4n-2,

then its length is

4n - 2 = 4 · 6 - 2

= 24 - 2

= 22

SInce the measure of the third side is given by 4n - 7,

then its length is

4n - 7 = 4 ·6 - 7

= 24 - 7

= 17

That is why the measures are 6, 22 and 17.

We know we're dealing with two dice. Since each die has 6 different possibilities, the outcomes of rolling two dice are given by:

6 × 6, which is 36. This will be our denominator.

How many ways can we get 9 or 12 with two dices?

For a sum of 9:

3 + 6 = 9

4 + 5 = 9

There are two possibilities.

For a sum of 12:

6 + 6 = 12

There is only one possibility.

Summing it up, there are 3 possibilities to get a sum of 9 or 12 with the two dice.

The events are independent events since neither of them can ever occur at the same time.

Thus, the probability will be:

Therefore, the probability is 1/12.
