Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = 
( multiply both sides by - 4 )
- 8 = k
t = 
← equation of variation
When a = 
, then
t = 
= - 24
Answer:
400 sq. ft.
Step-by-step explanation:
We gotta find the length of a side:
First, we divide 80 by 4, because the perimeter of a square is (4 x side):
80 ft. / 4 = 20 ft.
Second, we doing the normal area of a square equation:
= 400 square ft.
Which leads to out answer of 400 sq. ft.
Answer: OPTION C
Step-by-step explanation:
2. The parent function of a linear function is the simplest form of a linear function and this is:
f(x)=x. Because from this function we can make transformations that allow us to obtain the function f(x) = -2x + 2
3. If you take the parent function and make f(x)-1, then you have:
f(x)-1=x-1 (The function is shifted down 1 unit on the y-axis).
4. Then you make -2f(x), as following:
y=-2(f(x)-1)=-2x+2 (The function is reflected in the y-axis).
5. That is how you obtain the final function.
Answer:
Step-by-step explanation:
Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are 
of these parts in total. Because each of these parts make up 
of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.
The top left and bottom right both have one part shaded each for a total of 
parts.
The top right and bottom left have 
and 
parts shaded, respectively, for a total of parts.
Therefore, in total, there are 
parts shaded out of total parts.
Thus, the percentage of the total area that is shaded is:
.
Answer:
D)6 units
Step-by-step explanation:
the answer is D because since side AB have the same y coordinate then you would have to either subtract or add the x. if one point on x is negative and the other is positive then you would add. but if they were both positive or both negative then you would subtract the x.
