Answer:
The temperature decreased by 9 °F in <u>6 days.</u>
Step-by-step explanation:
Let the number of days it takes for the temperature to decrease by 9 °F be
.
Given:
Average daily temperature decreases by
°F.
Decrease of temperature in 1 day =
= 1.5 °F.
∴ Decrease in temperature in x days is
.
Now, as per question, decrease in temperature in 'x' days is 9 °F.
Therefore, 


Therefore, the temperature decreased by 9 °F in 6 days.
Answer:
2/x + 3/y = 5
Step-by-step explanation:
A linear equation refers to any equation that can be written in the form;
ax+b=0 or y - mx -c = 0
The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).
All the equations given are linear, except the last equation;
2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;
