Answer:
<h2>y = 2x - 3</h2>
Step-by-step explanation:
y = (slope)x + (y-intercept)
Cross multiply 3/10 and x/70. You get 10x=210. Divide by 10 and get x=21. So it drops 21 degrees. 70-21=49.
Answer:Yes, it is a function
Explanation:The relation is obtained by squaring the value of x and then adding 3.
This means that the equation would be:
y = x² + 3
Now, taking a look at this equation, we would find that each value of x would have only one value of y.
Since a function is defined as a relation in which each x-value has only one y-value, therefore, the given equation represents a function.
This can be illustrated more by graphing the given relation (graph is shown in the attached image).
You will find a parabola is formed where each x value has only one corresponding y-value.
Hope this helps :)
