ANSWER

A. 0

EXPLANATION

The first equation is

2x + 3y = 6

The second equation is

y=-2/3x-1

Let us rewrite the first equation in slope-intercept form.

3y =-2x+ 6

y =  -  \frac{2}{3} x + 2

We can see that both equations has the same slope,

m =  -  \frac{2}{3}

but different y-intercepts.

This implies that the two lines do not intersect because they are parallel.

Therefore the system has no solution.

Answer:

0

Because -2/3x-1=2-2/3x

-2/3x+2/3x=2+1

0=3

and that's wrong, so there is no solution.

Describe the graph of a system of equations that has no solution.
Thepotemich [5.8K]

<span>The solution for a system of equations is the value or values that are true for all equations in the system. The graphs of equations within a system can tell you how many solutions exist for that system. Look at the images below. Each shows two lines that make up a system of equations.</span>

 

<span><span>One SolutionNo SolutionsInfinite Solutions</span><span /><span><span>If the graphs of the equations intersect, then there is one solution that is true for both equations. </span>If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.</span></span>

 

When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations. When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.

 

Some special terms are sometimes used to describe these kinds of systems.

 

<span>The following terms refer to how many solutions the system has.</span>

What is 155.78=2.95h+73.18<br> a. 28<br> b. 36<br> c. 3.6<br> d. none of these
xz_007 [3.2K]

Answer:

a. 28

Step-by-step explanation:

Given:

155.78=2.95h+73.18

We need to evaluate given expression to find the value of 'h'.

Solution:

155.78=2.95h+73.18

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

155.78-73.18=2.95h+73.18-73.18\\\\82.6=2.95h

Now we will use Division property of equality and divide both side by 2.95 we get;

\frac{82.6}{2.95}=\frac{2.95h}{2.95}\\\\h=28

Hence After evaluating given expression we get the value of 'h' as 28.
