The figure shown below graphs the inequalities
y ≤ 2x + 1
y > -2x - 3

The shaded area shows the solution region.

we have

y\leq 2x+1 ------> inequality A

The solution of the inequality A is the shaded area below the solid red line

see the attached figure N 1    

y>-2x-3 ------> inequality B

The solution of the inequality B is the shaded area above the dotted blue line

see the attached figure N 2

therefore

The solution of the system of inequalities is the shaded area between the solid red line and the dotted blue line

see the attached figure N 3

therefore

the answer in the attached figure N 3

The equation of a parabola is shown.
WARRIOR [948]
The axis of symmetry for this parabola is the x-axis. The general form of the equation is:
4p(x-h) = (y-k)^2
where the focus has the coordinates of (h+p,k)

Manipulating the given equation to the general form:
4(1/3)(x-7)^2 = (y - 0)^2

Therefore the coordinates of the focus is:
(7+(1/3),0)

The answer is A.) (71/3,0)

Answer: -3x + 4, (2,-2)

Step-by-step explanation:

First, you want to get y alone on one side.

3x + y = 4

     -4    -4        subtract 4 to get it on the left side.

     -y     -y       subtract y to get it alone on the right side.

Your'e left with 3x - 4 = -y      divide the whole equation by -1 do get a pos y

You then have y = -3x + 4. That's the first part of your answer.

To get the second part plug in (-3x + 4) into the y of the first equation, this is the substitution part.

-2x + 5(-3x+4) =-14        distribute the 5...     -2x - 15x +20 = -14

add your like terms ( x and x)                       -17x + 20 = -14

Isolate your x by subtracting the 20, both sides  -20   -20

-17x = -34    divide both side by 17 you get x = 2 (---- this is your first coordinate in the pair in your answer. To get the y do the same but solve for y instead of x.
