Answer:the answer is 15
Step-by-step explanation:
Simple we add 25+25 and get 50. Then we subtract 65-50 and get 15
Answer:
y = 3.33x - 18
Step-by-step explanation:
In order for a line to be perpendicular to another, it must have a slope with the negative reciprocal
- Here in the equation y = -0.3z + 6 has a slope of -0.3 (can also be written as
) - A line that is perpendicular to this line will need to have a slope of 3.33 repeating (or
) - I will using fractions for simplicity and convert to decimals afterwards
Since we have our slope and the two points, we can plug them into y = mx + b to solve for b and write our new equation of a line
- Substituting in the values that we have we get:
- Simplifying we get -8 = 10 + b, making b = -18
Now that we have our slope and our y-intercept we can plug them into the same formula used before to find our perpendicular line:
which can also be written as y = 3.33x - 18
Given:
.
Exponential regression model is

To find:
The exponential regression representing the population of Lazy Town as a function of time in years.
Solution:
Exponential regression model is
...(i)
We have,
.
Substituting
and
in (i), we get.

Therefore, the exponential regression representing the population of Lazy Town as a function of time in years, is
.
Answer:
x=0
Step-by-step explanation:
3 = x + 3 + 6x
Combine like terms
3=7x + 3
Use order of operations to isolate x
3=7x + 3
-3 -3
0/7=7x/7
x=0/7 or 0
