Which BEST describes the system of equations?

Answer:

Inconsistent

Step-by-step explanation:

Given system of equations.

A) y-2x=4

B) y+2=2x

We will solve the system of equations to check the solutions and tell whether the system is consistent or inconsistent

Rearranging equation A, to solve for y in terms of x

Adding both sides by 2x

y-2x+2x=4+2x

y=4+2x

Substituting value of y we got from A into equation B.

4+2x+2=2x

Simplifying.

2x+6=2x

Subtracting both sides by 2x

2x-2x+6=2x-2x

6=0

This is never true. So, we can say the system of equation has no solutions as the equations of the lines given are parallel.

Any system of equation with no solutions is termed as inconsistent.

A 2-column table has 4 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1. The second column is label
JulijaS [17]

The growth factor of the exponential function represented by the table is 5.

The correct option is c.

<h3>What is the growth factor of the exponential function?</h3>

The growth factor of the exponential function is the ratio of the two consecutive terms (y-values).

The growth factor of the exponential function is given by;

\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\\

As per given, we have a table;

x         y

-2     0.004

-1       0.02

0       0.1

1        0.5

The value  \rm x_2 is -2 and \rm x_1 is -1.

Therefore,

the growth factor of the exponential function represented by the table would be :

\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\ \rm Growth\ factor=\dfrac{y(-1)}{y(-2)}\\\\\rm Growth\ factor=\dfrac{0.02}{0.004}\\\\ \rm Growth\ factor=5

Hence, the growth factor of the exponential function represented by the table is 5.

1 question for math............
Murrr4er [49]

Answer:

answer would be the first choice.

Step-by-step explanation:

you would need to factor out x from the expression, then factor out -3 from the expression, factor the expression using a^2-B^2=(a-b)(a+b), afterwards you factor out the 4 from the expression, and then the 3x. Next you would factor out 2x+1, reduce the expression with x-5, reduce the numbers with the greatest common divisor 2, you then reduce the expression with x-3, multiply the fractions, distribute 2 through the parenthesis, distribute the 3x through the parenthesis, and that should be all.

Profit:p=r-c;solve for c
eduard
If you would like to solve p = r - c for c, you can do this using the following steps:

p = r - c         /+c
p + c = r - c + c
p + c = r       /-p
p + c - p = r - p
c = r - p

The correct result would be c = r - p.

Find the sum of the arithmetic series given ai = 45, an = 85, and n = 5.
seraphim [82]

Answer:

C. 325.

Step-by-step explanation:

The last term a5 = 85

a1 = 45

Sum of n terms = n/2 (a1 + l)

So here we have n = 5, a1 = 45 and the last term l = 85

= (5/2)(45 + 85)

= 5/2 * 130

= 325.
