Answer:
a= 15
Step-by-step explanation:
Given
3a + b = 54 ← substitute b = 9
3a + 9 = 54 ( subtract 9 from both sides )
3a = 45 ( divide both sides by 3 )
a = 15
Answer:
Number of Significant Figures: 5
The Significant Figures are 3 2 5 5 4
You can find the x intercept of the equation by setting the value of y
to zero and solving the equation. Similarly you can solve the y
intercept by setting the value of x to zero and solving the equation.
Now while solving this rational function for intercepts if you face a
situation where the value in the denominator is zero it implies that
there is no intercept in that case as dividing something by zero is
indeterminate.
One such pair is 1/4 and 3/4
1/4 + 3/4 = (1 + 3)/4 = 4/4
= 1
Answer:

Step-by-step explanation:

Solution:
Equation of a line passing through points
is given by 
Take 
So,equation of line is evaluated as follows:

As per the graph,inequality is 
Here, use sign < and not
as line in the graph is dotted that is points on the line are excluded.
