When x=1, 7x+3 = 10.
When x=2, 7x+3 = 17.
When the value of 'x' changes from '1' to '2', the value of 7x+3 changes
from '10' to '17' . . . a distance of '7' .
That's what the ' 7x ' in the equation means, and that's what we mean
when we say that the 'slope' of the equation is '7'. 'y' changes '7' for
every '1' that 'x' changes.
The expression 400(1.12)^y is an exponential function
The true statement is that the growth rate of the fish in the lake is 12%
<h3>How to determine the true statement?</h3>
The expression is given as:
400(1.12)^y
The above expression is an exponential growth function,
Where:
- 4000 represents the initial value
- 1.12 represents the growth factor
Next, we calculate the growth rate (r) as follows:
r = 1.12 - 1
r = 0,12
Express as percentage
r = 12%
Hence, the true statement is that the growth rate of the fish in the lake is 12%

Your equation is x + (3+2x) + (2+x) = 45
x being the first number, (3+2x) being the second, and (2+x) being the third.
not sure if i was supposed to try to simplify. hope this helps!!
Find slope by finding the change in y over the change in x, or rise over run.

Final answer: A
Hello!
The denominators are equal, so we can simply combine the numerator:
Combine like terms in the numerator:
Factor out 2 from the entire fraction:
Cancel out 2 from both the numerator and denominator:
Factor the numerator to simplify further:
Cancel out x - 1:
