Answer:

The line x = 4 and y = - x - 1 has only one solution.

Step-by-step explanation:

Consider the provided graph.

The system of equation has the solution at the point where the line intersects.

Now consider the graph of the equation x = 4 and y = - x - 1

The graph of x = 4 is a vertical line.

From the graph it is clear that the line x = 4 and y = - x - 1 intersect at a point.

Now to calculate the number of solutions simply count the number of intersecting points.

By observing the graph it can be concluded that the graph of x = 4 and y = - x - 1 intersect only at one point i.e (4,-5).

Hence, the line x = 4 and y = - x - 1 has only one solution.

Find the midpoint of the segment from point a (6,3) to point B (8,1)
velikii [3]

Answer: M=(7,2)

Step-by-step explanation:

You need to use the following formula:

 M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})

Given the points A(6,3) and B(8,1), you can identify that:

x_A=6\\x_B=8\\y_A=3\\y_B=1

Now, you can substitute these values into the formula M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2}).

Therefore, you get this result:

M=(\frac{6+8}{2},\frac{3+1}{2})

M=(7,2)

Need help with math question
mote1985 [20]

Answer:

(-7,4)

Step-by-step explanation:

goal: (y-k)^2=4p(x-h)

y^2-8y=4x+12    Rearranged and added 4x and 12 on both sides

y^2-8y+(-8/2)^2=4x+12+(-8/2)^2 complete square time (add same thing on both sides)

y^2-8y+(-4)^2=4x+12+(-4)^2 (simplify inside the squares)

(y-4)^2=4x+12+16  (now write the left hand side as a square)

(y-4)^2=4x+28

(y-4)^2=4(x+7)    factored...

vertex is (-7,4)
