Answer:
You can substitute
4
as
x
in the first equation because
x
and
4
are equal.

29
8
+
y
=

Step-by-step explanation:
Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
And y is directly related to x
∝ 
Here k is constant of variation
--------------(1)
Put the and value in equation 1.
So, the constant of variation is 3.
Answer:
<h2>(f + g)(x) = x² + 3x - 5</h2>
Step-by-step explanation:
If we were to draw a best fit line, the y-interest would be near 15, and the slope would be negative.
In the options given, the slope is either -3 or -13. If we imagine a line through the plotted points, the rise would be about 15 while the run would be about 5. This means the slope is about -3.
The best answer is y = -3x + 15
