Mathematics
1 answer:
sweet [91]3 years ago
7 0

Answer:

The answer is A (-3,4,6).

Step-by-step explanation:

1 Solve for z in -3x-4y+z=-1


z=3x-1+4y



2 Substitute z=3x-1+4y into 2x+y-z=-8


-x-3y+1=-8



3 Substitute z=3x-1+4y into x+8y-z=23


-2x+4y+1=23


4 Solve for x in -x-3y+1=-8


x=-3y+9



5 Substitute x=-3y+9 into z=3x-1+4y


z=-5y+26



6 Substitute x=-3y+9 into -2x+4y+1=23


10y-17=23



7 Solve for y in 10y-17=23


y=4



8 Substitute y=4 into z=-5y+26


z=6



9 Substitute y=4 into x=-3y+9


x=-3



10 Therefore,


x=-3


y=4

z=6

A) Patty Stacey deposits $2600 at the end of each of 5 years in an IRA. If she leaves the money that has accumulated in the IRA
ruslelena [56]

Answer:

From the question, Stacey deposits $2600 six times over a thirty year period since she makes the deposit every five years. Her amount accures by the formular. A = P(1+r/n)^nt. Where her principal P = $2,600. Rate, r =6% =0.06. Time = 30 years and the period of compounding per unit time, n = 6 years. So we have A =2, 600(1+(0.06/6))^(6*30) = 2, 600 (1 + 0.01)^(180) = 2600* 5.9958 = $15, 587. To the nearest cent we have $15, 590.

A certain relationship is defined as having only one corresponding y-value for each x-value. Which of the following best describ
igomit [66]

Answer:

We conclude that a function is defined as having only one corresponding y-value for each x-value.

Hence, option (C) is true.

Step-by-step explanation:

We know that A function is a certain relationship is defined as having only one corresponding y-value for each x-value.

Considering the function

  • f(x) = x+1

Here,

  • x is the input and f(x) or y is the output.
  • 'x' is often called an independent value and y is called the 'dependent' value.

Considering the table

x                      y

1                      2

2                     3

3                     4

4                     5

The values in the table satisfy the function y = x+1.

It is clear from the table that the function has only one corresponding y-value for each x-value. In other words, there is no repetition of 'x' value.

Therefore, we conclude that a function is defined as having only one corresponding y-value for each x-value.

Hence, option (C) is true.

Graph the following exponential functions and determine the y-intercept, domain, range, and
Ne4ueva [31]

The graph of the exponential function f(x) = 5(2)ˣ is as shown in the attached file.

<h3>How to draw the graph of an exponential Function?</h3>

We want to draw the graph of the exponential function;

f(x) = 5(2)ˣ

At input of x = 0, we have;

f(x) = 5(2)⁰ = 5

At input of x = 1, we have;

f(x) = 5(2)¹ = 10

At x = -1, we have;

f(x) = 5(2)⁻¹ = 2.5

At x = -2, we have;

f(x) = 5(2)⁻² = 1.25
