Answer:
D) (2,5)
Step-by-step explanation:
The intersection of the 2 lines.
pls give brainliest.
A. Yes, the value of this function is 8 when x is 15.
B. False. I noted right away that the ordered pair (0,5) is not included, and some of the ordered pairs included do not represent the given function.
C. Yes, f(5) = 6. See (A) above.
D. False. The range of this function is the set of integers between 5 and 13 inclusive.

Answer:
(-1, 1)
Step-by-step explanation:
Hi there!
We want to solve the system of equations given as:
2x-3y=-5
3x+y=-2
Let's solve this equation by substitution, where we will set one variable equal to an expression containing the other variable, substitute the expression as the variable that it equals, solve for the other variable (the variable that the expression contains), and then use the value of the solved variable to find the value of the first variable
In the second equation, we have y by itself; therefore, if we subtract 3x from both sides, then we will get an expression that y is equal to.
So subtract 3x from both sides
y=-3x-2
Now substitute -3x-2 as y in the first equation.
It will look something like this:
2x - 3(-3x-2)=-5
Now do the distributive property.
2x+9x+6=-5
Combine like terms
11x+6=-5
Subtract 6 from both sides
11x=-11
Divide both sides by 11
x=-1
Now substitute -1 as x in the equation y=-3x-2 to solve for y:
y=-3(-1)-2
multiply
y=3-2
Subtract
y=1
The answer is x=-1, y=1; this can also be written as an ordered pair, which would be (-1, 1)
Hope this helps!

Answer:
The population in 1995
501170
Is the population increasing or decreasing?
The population is decreasing
The rate of population change
population in the year 2020
302439
Step-by-step explanation:
Since 1995 is the base year, the population in 1995 is simply found by setting x equal to 0 in the given function;
The population is clearly decreasing over time since the base of the exponent, 0.98, is less than 1.
The rate of population change is obtained by differentiating the function with respect to x using the rule;
The population in the year 2020 is obtained by setting x equal to 25 in the population function since 2020-1995 = 25;
