Mathematics
1 answer:
Kisachek [45]3 years ago
3 0

Step-by-step explanation:

2x +8y = 54

x + 9y = 67

x = 67 - 9y

2(67-9y) + 8y = 54

434 - 18y + 8y = 54

434 - 10y = 54

10y = 54 - 434

10y = -380

y = -38

Evaluate functions from their graph g(−9)=<br> See the Correct Answer Attached!
r-ruslan [8.4K]

Evaluating the function from the given graph, g(-9) = 1.

<h3>How to Evaluate a Function?</h3>

To find the value of a function for a given x-value using a given graph, trace the x-value against the corresponding y-value on the y-axis.

To evaluate the function from the graph given, for g(-9), find the y-value that corresponds to the x-value of -9.

The graph shows that when x = -9, the corresponding y-value is 1.

Therefore, g(-9) = 1.
