Answer:
Both plant and animal cells can have endoplasmic reticulum. Both plant and animal cells can have mitochondria. In animal cells, chromosomes contain the master plan for cell activities and cell development. The cell membrane controls which substances enter and leave a plant cell
Step-by-step explanation:
Answer:
The real perimeter is:

And the area would be:

Step-by-step explanation:
For this case we know one side of a square given 6mm.
We can begin calculating the perimeter for the scale figure with this formula:

The area for this case is given by:

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

And the area would be:

Answer:
y = -x - 1
Step-by-step explanation:
soo since we already know the slope we can subsitute it to the slope form equation
y = mx + b
y = -x + b
now to find the y intercept we have to subsitute the given point
-3 = -(2) + b
-3 = -2 + b
b = -1
Given:
The values of a linear function are
and
.
To find:
The linear function.
Solution:
If a linear function passes through two points, then the equation of the linear function is:

The values of a linear function are
and
. It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:




Adding 8 on both sides, we get


Putting
, we get

Therefore, the required linear function is
.
