Note that all answers have the same functions. The difference in the answers is where those functions are happening.

The parabola (x^2+4) happens for x-values less than 2. “Less than” because of the open circle at x=2.

The line (-x+4) happens for x-values greater than or equal to 2. “Greater than or equal to” because of the closed circle at x=2.

The answer that matches these is B.

3x+y+z=4 2x+2y+3z=3 X+3y+2z=5

zhenek [66]

1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2) 2x + 2y +3z = 3
- __________________
4x - z = 5

2)*3 6x + 6y + 9z = 9
3)*2 2x + 6y + 4z = 10
- __________________
4x+5z =-1

4x+5z = -1
4x - z =5
- ________
6z = -6
z = -1

If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
x=1

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
y=2

So z=-1, x=1, y=2

ratelena [41]

Answer:

$13.94

Step-by-step explanation:

$14.93 + $11.13= 26.06

$20+$20= $40.00

$40.00 - 26.06 = $13.94

Hope this helps!

Please help me with this :))

Hey love! <3

Answer:

Your answer is 306 units^2!

Step-by-step explanation:

Let's work this out together!

First let's find the top and bottom square's area.

6 x 15 = 90

Since there are not only two of those shapes but THREE, 90 x 3= 270.

So 270 is the surface area of the middle rectangles.

Step 2! Let's find the area of these triangles. We know that both of the triangles are 6 on each side.

Think back to geometry formulas. The formula for finding the area of a triangle is different then a square.

Triangle formula: Base x Height / 2 = A

Rectangle formula: Base x Height = A

So 6 x 6 is 36, now we have to divide it by two; which equals 18.

Since there are TWO triangles, we multiply 18 by two giving us the total surface area of the triangles, 36.

Now let's add our products together!

36 + 270 = 306

Thus the total surface area being 306 units^2

I need the domain to this.

aliina [53]

Answer:

all real numbers greater than zero

Step-by-step explanation:

The square root of a number must be greater than or equal to zero

sqrt(x) ≥0

Squaring each side

x ≥0

This means the domain is all real numbers greater than or equal to zero

I would go with all real numbers greater than zero since it is the closest answer
