Answer:
y=x-1
y=-2x-4
although I cant summon a graph for this one, I can give cords
for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)
For second graph the slope is down 2 over 1, and begins at (0,-4).
(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
Answer:
<em>A.(for weight in pounds)</em>
3, 4, 5, 6, 7
Median: 5
Mode: There are no mode in the following data set.
Mean: 3 + 4 + 5 + 6 + 7 = 25/5 = 25
<em>B.(for number of computers)</em>
4, 8, 18, 25, 45
Median: 18
Mode: There are no mode in the following data set.
Mean: 4 + 8 + 18 + 25 + 45 = 100/5 = 20
~hope this helps~
I would highly appreciate it if you b=would give me the brainliest~ :)
9 and 2/4 can be written as 9.5 in decimals. We usually round 5 up, so we would round it to 10.
if it was 9.4 we would round it down to 9.
Answer: Let's assume that the pig pens need to be fenced in the way shown in the diagram above.
Then, the perimeter is given by

The area of a rectangle is given by
A

Now, let's differentiate this function, with respect to y, to find any critical points on the graph.

Hence, the dimensions that will give the maximum area are

A graphical check of the initial function shows that the vertex is at
(

, which represents one of the dimensions that will give the maximum area and the maximum area, respectively.

Answer:
The correct option is;
It has no reflectional symmetry
Step-by-step explanation:
Reflectional symmetry is one such that a line can be drawn across a shape or figure and the shape or figure on either side of the line is the equivalent of the reflection image obtained from a mirror
Lines of reflectional symmetry can be found in squares, circles, and triangles
The characteristics of the object that has line of reflection symmetry remains the same across the line of symmetry
Two dimensional objects have lines of symmetry while three dimensional objects have planes of symmetry.
