Answer:
, explanation for how to get there
Step-by-step explanation:
If we have the equation
, we want to isolate c on one side and find it's value.
Let's first divide both sides by 4.

Now let's solve for the absolute value. We know that:

or

Possibility 1:

Subtract 3c from both sides:

Possibility 2:

Add 4c to both sides:

Subtract 5 from both sides:

Divide both sides by 7:

Plugging both of these values into the equation, we can see that only 5 works.

Answer:
The zeros of this function are x=(1,7)
Step-by-step explanation:
A transformation that changes the results in a similar, but not congruent figure would be dilation.

Answer: There are 72 index cards she needed.
Step-by-step explanation:
Since we have given that
Area of first bulletin board = 6 square foot
Area of second bulletin board = 12 square foot
Area of each index card is given by

So, Number of index cards needs for first bulletin board is given by

Number of index cards needed for second bulletin board is given by

Hence, Number of index cards she needed is given by

Therefore, there are 72 index cards she needed.
