Answer:
The domain for graph 1 is all real numbers, the range is y >= 0.
The domain for graph 2 is x >= 0, the range is y >= 0
Step-by-step explanation:
Graph 1: The x values are infinite for the graph, the y values will always be above zero and continue to be infinite.
Graph 2: The x values start at 0 and go to the right for infinity, the y values start at 0 and continue to infinity.
Ratio of girls : boys = 5 : 4
<u>Find total parts:</u>
Total parts = 5 + 4 = 9
<u>Find 1 part:</u>
9 parts = 36
1 part = 36 ÷ 9 = 4
<u>Find 5 parts (Girls):</u>
Girls = 5 parts = 4 x 5 = 20
Answer: There are 20 girls.
90 miles driving at 45 mph for 2 hours
/ means divide, so U( an unknown value ) / 6 = 9. to get the answer, simply multiply 6 x 9
