Answer:
A
Step-by-step explanation:
Given the 2 equations
4x + 5y = - 12 → (1)
- 2x + 3y = - 16 → (2)
Eliminate the x- term by multiplying (2) by 2 and adding the result to (1)
- 4x + 6y = - 32 → (3)
Add (1) and (3) term by term
11y = - 44 ( divide both sides by 11 )
y = - 4
Answer:
The Triangle
Step-by-step explanation:
Answer:
The answer is 8a-28b+15c
Step-by-step explanation:
Equations:
x + y = 26
x - y = 4
---
Add to get:
2x = 30
x = 15
---
Solve for "y":
x + y = 26
15 + y = 26
y = 11 (smaller number)
We need to position the four points so they all are on the graph of an exponential function.
As an example of an exponential function, let's use the following function:
Now, to find where the points should be located, let's choose some values of x and calculate the corresponding values of y:
Therefore the points should be located at (-2, 1/4), (-1, 1/2), (0, 1), and (1, 2).
