Answer: (C) shifts 6 units to the LEFT
<u>Step-by-step explanation:</u>
The vertex form of an absolute value equation is:
y = a |x - h| + k where;
- a is the vertical stretch (irrelevant for this problem)
- (h, k) is the vertex
Since h represents the x-coordinate and the x-axis is left to right, then h shifts the graph left or right.
- If h is negative, the graph shifts to the left.
- If h is positive, the graph shifts to the right.
x + 6 is actually x - (-6), so h is negative and the graph shifts to the left.
Part A:
f(x)=30(1.2)^x
f(x)=45+3x
Part B: Neighborhood A is 74.6496, so that rounds to 75 homes, and Neighborhood C is exactly 60 homes
Part C:
i would graph them in a graphing calculator, and use the functions to see where the 2 lines intersect.
The x value for when they intersect (# of years) is 3.3207883, so approx. 3.3 years for them to be equal
Answer:
x=17/13
Step-by-step explanation:
-3(3x-3)=4/5(5x-10)
-9x+9=4x-8
-13x= -17
x=17/13
first, find the ratio of 30/24
30/24=
15/12=
5/4
25 divided by 5/4= 20
0.45 (weight of each cupcake) *100 (number of cupcakes) = 45
The box of 100 cupcakes will weight 45 pounds. :)
