164 is the answer. :)))))))
Answer:
$210
Step-by-step explanation:
Given data
time = 6 weeks
initial amount= $90
saving per week = $25
Hence the expression for the total savings after the 6 weeks is given as
y= mx+c
where
m= $25
x= 6 weeks
c= $90
substitute
y=25*6+90
y= 150+60
y= $210
Hence the total amount after 6 weeks is $210
The 3-D shape would be created if the figure was rotated around the x-axis is a cone
<h3>What are 3-D shapes?</h3>
3-D shapes (short form of 3-Dimensional shapes) are shapes that have width, length and height
<h3>How to determine the 3-D shape?</h3>
The coordinates are given as:
(0, 0), (-3, -4) and (-3, 0)
When the above coordinates are plotted on a coordinate plane and the points are connected;
We can see that the points form a right-triangle
See attachment for the shape
As a general rule
Rotating a right-triangle across the x-axis would form a cone
Hence, the 3-D shape would be created if the figure was rotated around the x-axis is a cone

For problem 1, the rate of change is 1/4.
For problem 2, the rate of change is -4/10, or -2/5.
