Use the substitution method to solve each linear system. 4x - 3y = -13,-2x + y = 4

Contact [7]

Answer:

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}4x-3y=-13\\ -2x+y=4\end{bmatrix}$

Isolate x for for 4x-3y=-13

$4x-3y=-13$

$4x=-13+3y$

Divide both sides by 4

$x=\frac{-13+3y}{4}$

substitute y=5

$x=\frac{-13+3\cdot \:5}{4}$

$x=\frac{1}{2}$

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

I don’t like to beg but I guess I’m in need..

Answer:

-4 < n ≤ 5

Step-by-step explanation:

Since the left inequality is an open circle and going to the right, the sign will be >

Since the right inequality sign is a closed circle and is going left, the sign would be ≤

The open circle ends at -4 so, n > -4

The closed circle ends at 5 so, n ≤ 5

You combine them and it looks like this:

-4 < n ≤ 5

Drag a description to match each equation.

AnnZ [28]

Given:

The descriptions and equations. The equations are

$y=4x$

$y=x+4$

To find:

The correct description for each equation and match them.

Solution:

We know that, "+" is used for more and "×" is used for times.

Additive: y is 4 more than x.

$y=x+4$

Additive: x is 4 more than y.

$x=y+4$

Multiplicative: y is 4 times x.

$y=4x$

Multiplicative: x is 4 times y

$x=4y$

Therefore, the correct description for the equation $y=4x$ is "Multiplicative: y is 4 times x " and the correct description for the equation $y=x+4$ is "Additive: y is 4 more than x. "
