Answer:
8.76
Step-by-step explanation:
Simplifying
15.00 + -6.24 = b
Combine like terms: 15.00 + -6.24 = 8.76
8.76 = b
Solving
8.76 = b
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-1b' to each side of the equation.
8.76 + -1b = b + -1b
Combine like terms: b + -1b = 0
8.76 + -1b = 0
Add '-8.76' to each side of the equation.
8.76 + -8.76 + -1b = 0 + -8.76
Combine like terms: 8.76 + -8.76 = 0.00
0.00 + -1b = 0 + -8.76
-1b = 0 + -8.76
Combine like terms: 0 + -8.76 = -8.76
-1b = -8.76
Divide each side by '-1'.
b = 8.76
Simplifying
b = 8.76

The value of the output r(-3) in the given function is 2.
<h3>How to Interpret Graphs?</h3>
When we talk about graphs like this, it is pertinent to note that the x-values are the input values which would give us corresponding y-values which are the output values.
Now, we want to find r(-3) from the graph. This means we want to find the value on the y-axis when x = -3.
From the given graph, we see that when x = - 3, it is traced that the value of the output is y = 2.
Thus, the value of the output r(-3) in the given function is 2.

Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°)
Answer:
5
Step-by-step explanation:
Significant figures are usually non-zero numbers. The only time 0 is a significant figure is when it is in between 2 non-zero numbers.
50.003
This number has 5 figures
There are 3 0s, but they are in between 2 non-zero numbers (5 and 3). Therefore, all 5 digits are significant figures.
So, there are a total of 5 significant figures.
