Answer:

(-1, 4)

(-0.231, 0.769)

(4, 1)

(-2, -3)

(-4, -4)

No solution since graph didn't intersect at any point.

Step-by-step explanation:

The pair of the linear equation of two variables is of the form:

a₁x₁ + b₁y₁ + c₁ = 0

a₂x₂ + b₂y₂ + c₂ = 0

For solving these equations we will plot the graph of these equations in the same graph paper.

Firstly we will make a value table by putting the value of one variable so, we will get the value of another variable. Now plotting these points in the graph and then join the line. Graph will be plotted.

Now, we can have three possibilities, that is:

Both lines will intersect, then we have only one solution.

both lines will coincide, then we have infinitely many solutions.

Or Both lines can be parallel i.e. they will not intersect at any point, then we have no solution to the given equation.

And the point of intersection is the solution of the graph.

The graph of given equations is plotted below.

Find the slope of the line through the points (4,2) and (6,2).
olganol [36]

Answer:

The slope is m=0

Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.

Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.If y-coordinates are equal and x-coordinates are not equal (as in our case), then the slope equals 00 (the line is horizontal).

7(x+4)−6(x+3)=x+5 what is x
shusha [124]

Answer: No solution

Step-by-step explanation:

7(x+4) - 6(x+3) = x + 5

7x + 28 - 6x - 18 = x + 5     distributing

7x - 6x - x = -28 + 18 +5

0 = -5       <u>Not true</u>

No solution

Does an equation always have a solution? Could you come up w/ an equation that does not have a solution? If yes, explain why thi
Damm [24]
An equation does not always have a solution. Sometimes, an equation can have a variable that does not equal the remaining value on the other side. For example, root negative x could never equal a number squared.
√-x ≠ 14²
This equation cannot have a solution because you can't square any number to get a negative solution. Therefore, x= no solution.

Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20​
earnstyle [38]

Answer:

Step-by-step explanation:

8x+5y = 20

y = (-8/5)x + 4

slope of the line is -8/5.

slope of any perpendicular to the line is ⅝.

line of slope ⅝ that passes through P(4,5):

y-5 = ⅝(x-4)

y = ⅝x + 2.5

find intersection of lines

⅝x + 2.5 = (-8/5)x + 4

25x + 100 = -64x + 160

89x = 60

x = 60/89, y = 260/89

distance between (60/89, 260/89) and (4,5) = 3.92
