Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
----> 
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
Answer:
Option B is correct.
The reflection rule is followed here is, 
.
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.
Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is,
Use the distance formula and simply substitute in the corresponding orders pairs.
Distance = √(x2 - x1)² + (y2 - y1)²
Distance = √(4 - (-6))² + (3 - (-1))²
Distance = √(4 + 6)² + (3 + 1)²
Distance = √(10)² + (4)²
Distance = √100 + 16
Distance = √116
Distance = 10.7703296143
Round to the nearest hundredth!
Distance ≈ 10.77
Answer:
Step-by-step explanation:
<u>Given points:</u>
<u>Use slope formula:</u>
If you try to solve for x it is not able to be solved because the variable must be located in between the inequality signs, but if i simplified your problem then it would be: x is greater than or equal to -2.
I really hoped this helped. Good luck.
