Answer:
3x+12y+4 -- is the simplified version, variables would be x and y
Answer: Red is 0.18 And Blue is 0.68
Step-by-step explanation:
Look at sizes and comparisons between the sizes and all together should add to 1
Answer:
check it..
Step-by-step explanation:
domain and range...
50 -> 35=change by 15
change by 5=10%
so multiply by 3
3(5)=3(10%)
15=30%
Answer:
x-intercept:
A line that crosses the graph at x-axis.
i.e substitute y = 0 and solve for x.
As per the statement:
A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water
Given the graph:

Substitute y = 0 we have;

⇒
⇒
⇒
⇒
⇒
By zero product property we have;
x-20 =0 and x+10 = 0
⇒x = 20 and x = -10
Therefore, the x-intercept represents the water has no larvae at −10 degrees Celsius and 20 degrees Celsius.
