Answer:

x = 7

Step-by-step explanation:

We know that adding TUW and WUV will give TUV.

So you can substitute the given equations for each and form a lengthy equation

5x + 3 + 10x -5 = 17x - 16

Move all the variables to one side, and the constants to the other

5x + 10x - 17x = -16 - 3 + 5

Simplify!

-2x = -14

x = 7

What is the rang for the equation y=2x-3​
a_sh-v [17]

Answer:

The range for the equation is all real numbers.

Step-by-step explanation:

The range of an equation is the set of y-values that you can get by plugging in all possible x-values.

Another way to put it is, when you graph the equation, whatever y-values the line produces, is its range.

Graphing y=2x-3, you can see it is a graph with a positive slope that extends from negative infinity y-value to positive infinity x-value.

A house worth $70,000 when purchased was worth $67,000 after the first year and $64,000 after the second year. If the economy do
Citrus2011 [14]

Answer:

a) The formula for the sequence is

a_n = 67,000 -3,000(n-1)

b) a_7 = 49,000

Step-by-step explanation:

Note that the difference between any two consecutive terms in the sequence is always equal to $3,000

67,000-70,000= -3,000\\\\64,000-67,000=-3,000

Then we have an arithmetic sequence where each term increases by a magnitude of 3,000 with respect to the previous term.

The explicit formula for an arithmetic sequence is:

a_n = a_1 +d(n-1)

Where d is the common difference between the consecutive terms of the sequence

d = -3,000

a_1 is the first term, or the value of the house after year 1 a_1= 67,000

n represents the number of years since the house was purchased

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

a) Then the formula for the sequence is

a_n = 67,000 -3,000(n-1)

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

---------------------------------------------------------------------------------------------

b) Now we can use the formula to find the price of the house after 7 years

a_7 = 67,000 -3,000(7-1)

a_7 = 67,000 -3,000(6)

a_7 = 49,000
