For one batch of cookies, the ratio of ounces of butter to ounces of flour is 2 to 3

dezoksy [38]

Solve the following system of inequalities graphically on the set of axes below. State

Serhud [2]

Answer:

$(x,y) = (-1,1)$

Step-by-step explanation:

Given

$y>-2x - 1$

$y>x + 2$

Required

Solve graphically

See attachment for graph;

The black shade represents $y>-2x - 1$

While the green, represents $y>x + 2$

Next, determine the intersection points between the two lines

From the attached graph, we have:

$(x,y) = (-1,1)$

<em>Hence, the solution is:</em> $(-1,1)$

Two lines, A and B, are represented by the equations given below!

lara [203]

Answer:

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.

Step-by-step explanation:

Given the system of the equations

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

Arrange equation variables for elimination

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

$y-3x=4$

$-$

$\underline{y-x=-4}$

$-2x=8$

$\begin{bmatrix}y-x=-4\\ -2x=8\end{bmatrix}$

solve for x

$-2x=8$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{8}{-2}$

$x=-4$

$\mathrm{For\:}y-x=-4\mathrm{\:plug\:in\:}x=-4$

$y-\left(-4\right)=-4$

$y+4=-4$

$y=-8$

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.
