Answer:

Step-by-step explanation:
we have

Solve for t
That means ----> Isolate the variable t
Multiply by b both sides to remove the fraction

Factor the variable t in the left side
![t[b+a]=b](https://tex.z-dn.net/?f=t%5Bb%2Ba%5D%3Db)
Divide by (b+a) both sides

Answer:
A table
Step-by-step explanation:
A table has four legs ( supports) but cannot possibly walk because it is not a living thing. For example, see the table in the attachment, it has four legs (supports) but cannot possibly walk.
The slope on the given graph is 2.
Given,
A graph is given in the figure.
We need to find the slope of the graph.
<h3>What is a slope in a graph?</h3>
A slope is a measure of its steepness.
It is given by:
We need to find two points on the graph.
Example: Two points are - (a,b) and (c,d)
Slope = (d - b) / (c - a)
Find two points from the graph.
We have,
(1.5, 0) and (0, -3)
Now,
Slope:
= (-3 - 0) / (0 - 1.5)
= -3 / -1.5
= 2
Thus the slope on the given graph is 2.
