The first line in the system of equations is graphed on the coordinate plane. Graph the second line to find the solution to the

ruslelena [56]

Answer:

the given system is

The first line is already graphed.

We want to graph

We can do this by plotting two points and drawing a straight line through them.

When we choose x=0, we substitute into the equation and solve for y.

So we plot (0,-4)

Also, when y=0, we substitute and solve for x.

So we plot the point (-4,0)

We now use a straight edge to draw a straight line through these two points to obtain the graph shown in the attachment.Step-by-step explanation:

A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and ye

nexus9112 [7]

Answer:

$Blue = 12$

$Yellow = 9$

Step-by-step explanation:

Given

$Blue : Yellow = 4 : 3$

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

$Total = 4 + 3$

$Total = 7$

The blue and the yellow pint can be represented individually as:

$Blue = \frac{4}{7} * Green$

$Yellow = \frac{3}{7} * Green$

Number of blue paint calculated last week is:

$Blue = \frac{4}{7} * 21$

$Blue = {4} * 3$

$Blue = 12$

$Yellow = \frac{3}{7} * Green$

$Yellow = \frac{3}{7} * 21$

$Yellow = {3} * 3$

$Yellow = 9$
