Answer:
(2,6)
Step-by-step explanation:
x-y=-4 -----> Get the one of the variables by themselves
x=-4+y -----> All i did was adding the y to the the other side to get x by itself
Now all you do is to substitute the in the equation into the other equation
x=-4+y --------------> 6(-4+y)-4y=-12
Then solve
Now since you have your y now all you need to do is to do the same thing
Substitute the y in for the other equation
Then there you go
Answer:
1. No solutions
2. One solution
3. No solutions
4. Infinitely Many
Step-by-step explanation:
Answer:
C. (3,6)
explenation
We are given that,
The point (-3,-6) is transformed by the rule .
That is, the point is reflected across y-axis and then reflected across x-axis.
That is, the rule for the transformation is (x,y) → (-x,y) → (-x,-y).
So, we get,
(-3,-6) → (3,-6) → (3,6)
Thus, the co-ordinates of the image are (3,6).
So, option C is correct.
1. Living Things are Composed of Cells:
Single-cell organisms have everything they need to be "self-sufficient". In multicellular organisms, specialization increases until some cells do only certain things.
2. Different Levels of Organization:
Living things must be able to organize simple substances into complex ones.
Living things organize cells at several levels:
Tissue - a group of cells that perform a common function.
Organ - a group of tissues that perform a common function.
Organ system - a group of organs that perform a common function.
Organism - any complete living thing
3. Living Things Use Energy:
Living things take in energy and use it, for maintenance and growth.
4. Living Things Respond To Their Environment:
Living things will make changes in response to a stimulus in their environment. A behavior is a complex set of responses.
5. Living Things Grow:
Cell division - the orderly formation of new cells.
Cell enlargement - the increase in size of a cell. Cells grow to a certain size and then divide.
An organism gets larger as the number of its cells increases.
6. Living Things Reproduce:
Reproduction is not essential for the survival of individual organisms, but must occur for a species to survive.
All living things reproduce in one of the following ways:
Asexual reproduction - Producing offspring without the use of gametes.
Sexual reproduction - Producing offspring by the joining of sex cells.
7. Living Things Adapt To Their Environment:
Adaptations are traits giving an organism an advantage in a certain environment.
Variation of individuals is important for a healthy species.
