Answer:

  infinite solutions

Step-by-step explanation:

Eliminate parentheses and collect terms:

  3x -12 +5 -x = 2x -7

Is X/3=5+3y/4 a linear equation
Svet_ta [14]

Answer:

Yes

Step-by-step explanation:

<h3>Linear Equations</h3>

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

<h3>What is a Linear Equation?</h3>

An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.

Solve the system of equations by graphing. x+y=-9 4x+y=-19
shutvik [7]

For this case we have the following system of equations:

x + y = -9\\4x + y = -19

We multiply the first equation by -4:

-4x-4y = 36

We have the following equivalent system of equations:

-4x-4y = 36\\4x + y = -19

We add the equations:

-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}

We find the value of the variable "x":

x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}

Thus, the solution of the system is:

(x, y): (- \frac {10} {3}, - \frac {17} {3})

See the graphic in the attached image

ANswer:

(x, y): (- \frac {10} {3}, - \frac {17} {3})

Use the annual compound interest formula to find the amount in the savings account at the end of the time period and then find t
icang [17]

Answer:

$9,216 in account $1,261 interest.

Step-by-step explanation:

The compound interest is given by:

a = p(1 +  \frac{r}{n})^{nt}

P = Principal

r = rate

n = Number of times interest is compounded per unit t

t = time

so:

a = 8000(1 +  \frac{0.05}{1} ) ^{1 .3}  \\ a = 9261

therefore, the answer is:

$9,216 in account $1,261 interest
