Answer:

Given; Addition Property of Equality; Division Property of Equality

Step-by-step explanation:

The first blank restates the equation we are given. This is why the justification for it is "Given."

To get the second blank from the first one, we must add two to each side. The property that allows this is the addition property of equality.

To get the third blank from the second one, we must divide both sides by 3. The property that allows this is the division property of equality.

Answer:

The cost in 2015 will be $283.45.

What is the reference point (t=0)?

d. The year 2005.

Step-by-step explanation:

The exponential growth model for the cost is the following:

$C(t) = C_{0}e^{rt}$

In which C(t) is the cost after t years, $C_{0}$ is the initial cost and r is the decimal inflation rate

In this problem, we have that:

$C_{0} = 190, r = 0.04$

What will it cost in 2015 assuming the rate of inflation remains constant?

2015 is 10 years after 2005, so this is C(10).

$C(t) = C_{0}e^{rt}$

$C(10) = 190*e^{0.04*10} = 283.45$

The cost in 2015 will be $283.45.

The reference point is the year in which t = 0, so the year 2005.

Answer:

Step-by-step explanation:

2 and 4 are on opposite sides of the transversal but both on the inside of the parallel lines. This makes them alternate interior angles, which are congruent.

The sum of 6 even integers is 130 what is the 2nd number in the sequence

castortr0y [4]

Answer:

The 2nd number in the sequence is $2\left(\frac{100}{12}\right)+2$

Step-by-step explanation:

Let the six even numbers be 2x,2x+2,2x+4,2x+6,2x+8,2x+10

We are given that The sum of 6 even integers is 130.

So,2x+2x+2+2x+4+2x+6+2x+8+2x+10=130

12x+30=130

12x=100

$x=\frac{100}{12}$

So,the 2nd number in the sequence is $2\left(\frac{100}{12}\right)+2$
