The correct answer would be: 50-(3x+4y+25) because the sum of what's in parethese is what it cost Sianna to buy all of it.
Answer:
Final point:
(18,35)
Step-by-step explanation:
This is because the x=intercepts are increasing at a constant rate of 10.
Hope this helps :)
I believe the answer is a
For each of the given answer choices, substitute the x-value into the given equation f(x) = 3(1/4)^x and see the equation gives the same f(x), or y-value.
Remember f(x) is the same thing as y and so coordinates for a point are in problem is (x, f(x))
Let's try the first coordinate (-2, 48). The x-value given by the coordinate is -2 and the f(x) value is 48.
Substituting x as -2
into the equation,
This matches with the answer choice (-2, 48) so A should be correct.
But you can also check the other answer using the same process to make sure.
