The attached
graph tells me that the domain is [-k,∞) and the range of this function
is (-∞,c]. The correct
answer between all the choices given is the second choice or letter B. I am
hoping that this answer has satisfied your query about this specific question.
Answer:
(7, 2 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 17 → (1)
x - 3y = 1 → (2)
Rearrange (2) expressing x in terms of y by adding 3y to both sides
x = 1 + 3y → (3)
Substitute x = 1 + 3y in (1)
3(1 + 3y) - 2y = 17 ← distribute and simplify left side
3 + 9y - 2y = 17
3 + 7y = 17 ( subtract 3 from both sides )
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into (3) for corresponding value of x
x = 1 + 3(2) = 1 + 6 = 7
Solution is (7, 2 )
<span>Graphing calculators are more accurate and are faster when finding the solution(s). <span>When solving a system of equations with a graphing calculator, you can have the calculator graph equations of any degree and shape. The graphing calculator also has functions to find where the graphs intersect between two points and are accurate sometimes to ten decimal places. When compared to graphing by hand you can get inaccurate results and results that are not as precise.</span></span>
