You can obtain the red graph by reflecting the black graph over the y axis.
Reflections over the y axis are obtaining by changing the orientation of the x axis, i.e. by mapping
So, in particular, given a function f(x), you reflect it over the y axis by writing f(-x).
You only need to observe that
to conclude the exercise.
54 hundreds is the answer
Answer:
a) 6x + 18 = 84
b) 11 yards
Step-by-step explanation:
a) You have that Jennifer made 6 identical curtains. If you chose x as the number of yards of fabric used for one curtain, you have that the total number of yards in the 6 curtains o fabric is
Furthermore, if you sum 18 yards to the 6x yards, the total amount of yards must be 84. Thus, you have the following equation:
b) Next, you solve the equation for x:
Then, 11 yards were use to make each curtain.
Answer:
no solutions
Step-by-step explanation:
6(x+1)=-2(3x+9)
distribute both sides first then you get:
6x+6=6x+18
then subtract 6x from 6x and 6 from 18.
0=12
therefore there are no solutions
The answer would be B I believe.
