Step-by-step explanation:
ik just trust because first one is less than so its undefined and the other is less then or equal to
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.

Answer:
(x, y, z) = (2, 2, -1/2)
Step-by-step explanation:
Most manual solutions to a system of 3 equations in 3 unknowns are ad hoc. The idea is to take advantage of any relationships that might exist between the coefficients.
Multiply the first equation by 2, then subtract the third equation.
2(2x -y -4z) -(x -2y) = 2(4) -(-2)
4x -2y -8z -x +2y = 8 +2 . . . . . . . eliminate parentheses
3x -8z = 10 . . . . . simplify
Now, we can subtract this from the second equation:
(3x -2z) -(3x -8z) = (7) -(10)
6z = -3 . . . . . . . simplify
z = -1/2 . . . . . . . divide by 6
Using the second equation, we can find x:
3x -2(-1/2) = 7
3x = 6 . . . . . . . . subtract 1
x = 2 . . . . . . . . . divide by 3
Using the last equation, we can find y:
2 -2y = -2
1 -y = -1 . . . . . . divide by 2
y = 2 . . . . . . . . add y+1
The solution is ...
(x, y, z) = (2, 2, -1/2)

6. A rectangle has a perimeter of 62 feet. If its length is 9 feet longer than its width, find
the dimensions of the rectangle.
62ft
Answers
Answer:
length = 20 ft, width = 11 ft
Step-by-step explanation:
let w be width, then length = w + 9
The opposite sides of a rectangle are equal , then
2w + 2(w + 9) = 62
2w + 2w + 18 = 62
4w + 18 = 62 ( subtract 18 from both sides )
4w = 44 ( divide both sides by 4 )
w = 11
and w + 9 = 11 + 9 = 20
then width = 11 ft and length = 20 ft

A net of a triangular prism is show. What is the surface area, in square feet, of the triangular prism?
44 square feet
96 square feet
108 square feet
120 square feet
Answers
To find surface area, all you need to do is add up the areas of all the faces of the prism. Let’s start by remembering some basic area formulas:
Area of a triangle= 1/2*base*height
Area of a rectangle= length*width
First, find the area of each of the little triangles on the sides of the net. The base is 3 ft, and the height is 4 ft. So:
1/2*3*4= 6 ft
There are two triangles of the same size, so multiply that number by 2.
6*2=12
Now, find the area of the top rectangle:
3*8= 24
And the area of the bottom rectangle:
5*8= 40
Finally, add all of those numbers together:
12+24+40= 76 ft^2
That should be your answer!

Answer: Ray AC is correct
This is because ray AE points in the same direction along ray AC. Put another way, points C and E are on the same line as A. So relabeling from "ray AE" to "ray AC" does not change the ray itself.
Keep in mind that order is important. So saying "ray AE" is completely different from "ray EA" due to the fact that the first letter is the endpoint while the second letter is where the ray goes on forever. So we can think of starting at point A and going in the direction of E to get ray AE, or going in the direction of C to get ray AC, and we're talking about the same ray.

−100D, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 36, end fraction, left parenthesis, x, minus, 60, right parenthesis, squared, minus, 100
What is the lowest altitude Ying will reach?
Answers
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
Given expression
y=1/36(x-60)²-100Compare to the vertex form
y=a(x-h)²+kWe get
.
a=1/36(h,k)=vertex=(60,-100)As a is positive parabola is opening upwards and vertex is minimum
Lowest altitude is -100m

here from right to left we add a single number and write it under the line, if the sum is above 1 decimal value the value upto 1 decimal from the very right of that number is written , for example in case of 9+8 that would be 17 so we would write 7 and carry 1, and the oposite of that for subtraction
