Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
16, 36, 40
Set the problem up as 4x+9x+10x= 92
26x= 92
X= 4
Plug back in to get the lengths of the sides (shown above)
Answer:
Function B has the greater rate of change
Step-by-step explanation:
Function A has a slope of 1/3
Function B has a slope of 1/2
When comparing slopes, the higher value has the greater rate of change
1/2 > 1/3
Answer: The expression simplified is 14.9d+3.6h-17.
Step-by-step explanation:
15. The answer that best fits the question would be the "First" option. the ( and ) are just things to say do the inner work first, then multiply.
16. The Third option is the answer that best fits the question. She is trying to find how many time she did something, so multiplication would be the answer.
Hope this helps!
