When X = 2, we substitute this value into the equation f(x) = 3x-1
3(2)-1 = 6-1=5
f(x)=5
Answer:
4 and 15
Step-by-step explanation:
Let the two numbers be a and b.
The sum of the two is 19. Therefore:

One number (let's use a) is 7 <em>more</em> than twice the other. Thus:

Solve for the system of equations. Substitute the second equation into the first:

Subtract 7 from both sides:

Combine like terms:

Divide by 3:

So, b is 4.
And since they add up to 19, this means that a is:

So our numbers are 4 and 15
And we are done :)

Answer:
Yellow: 
Step-by-step explanation:
tangent = opposite
adjacent
Opposite A = 16
Adjacent A = 30 (Not 34, since that is the hypotenuse or the longest line in the triangle)
Thus, tan A = 
Answer with explanation:
To solve , f(x)=g(x)
The three methods that we generally use to solve above equation is
1.→ Graphing technology
2.→Tables of values
3.→Successive approximation
→If you will use "Table of values" ,you will substitute the value of x in both f(x) and g(x) ,so after hit and trial you can find exact value of x, where , f(x)=g(x).
→The method of "Successive approximation" is used by selecting an Interval and then values of x are substituted from the interval to calculate the exact value of x for which, f(x)=g(x) by hit and trial method.Little bit lengthier and time consuming.
→ "Graphing technology"=Draw graph of both f(x) and g(x) .The point where these two function intersect gives the value of x.Tough to draw the graph of some function but gives exact answer once you have accomplished the drawing of Graph.
⇒"Graphing technology" is the method that would be preferred to calculate ,f(x)=g(x), to calculate x.
