Answer:
A) ((x+1)^2)-3
B) f(x) = 2(x+1)^2 is vertically stretched upwards by a factor of 2. In addition to this, it’s minimum value remains on the x-axis, due to there being no vertical translation like in the equation on part A.
So: The equation in part A has no vertical stretch, and does have a vertical translation, however it retains the same horizontal translation.
Explanation:
You can see the transformations by looking at the vertex and at least 1 other point.
Since it is a parabola we can start by saying:
f(x) = x^2
We also see a vertical translation of 3 units down:
f(x) = (x^2)-3
Lastly, we see a horizontal translation of 1 unit to the left:
f(x) = ((x-1)^2)-3
Answer:
- 120
Step-by-step explanation:
call x is the number you want to find
- (3/4 )x + 3
= (2/3)x - 6 - (3/4)x + (7/2) = (2/3)x - (13/2)
- (3/4)x - (2/3)x = - (13 /2) - (7/2)
- (1/12)x = -10
- x = -10 / (1/12) = -120
Answer:
3
Step-by-step explanation:
Answer: 47 your welcome :)
To get 75 decreased by 40% you subtract 40% from 100%.
100 - 40 = 60
So to get 60% of 75 you multiply .60 by 75.
.60 x 75 = 45
You have $45 now, but you have to decrease it by 40% again. You do the same process, so we need to multiply .60 by 45.
.60 x 45 = 27
So, the final result is $27.
