Write an equivalent expression to 2x + 3 + 5(x+ 6) by combining like terms

Mathematics
1 answer:
cestrela7 [59]3 years ago
8 0

Answer:

7x + 33

Step-by-step explanation:

Distribute the multiplication in the last term:  5(x + 6) becomes 5x + 30.  Then,  2x + 3 + 5(x+ 6) becomes 2x + 3 + 5x + 30.  2x and 5x are 'like terms' and add up to 7x; 3 and 30 are also like terms of a different type (constants) and add up to 33.  

Thus we have the equivalent, simpler expression 7x + 33.

Answer:

{f}^{ - 1} (x) =  \frac{2}{x - 6}  + 1

Step-by-step explanation:

we will subistitute f(x) by y and solve the equation in order to get the value of x,

then we subistitute x by y and y by x and y=f^-1(x)

Which graph represents the function f(x)=5lnx?
anastassius [24]

Answer:

The first graph (top-left) is the correct graph.

Please, also check the attached graph.

Step-by-step explanation:

Given the function

f\left(x\right)=5\:lnx

First, we should determine the x and y-intercepts.

Determining the y-intercept:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

Thus,  

substitute x = 0 in the function

y = lnx

y = ln(0)

y = undefined

Therefore, at x = 0, the value of y becomes undefined.

Hence, None is the y-intercept.

Determining the x-intercept:

We know that the value of the x-intercept can be determined by setting y = 0 and determining the corresponding value of x.

Thus,  

substitute y = 0 in the function

0 = ln(x)

Flipe the equation

ln(x) = 0

Solve algorithm

ln(x) = 0

Take exponent of both sides

\:e^{ln\left(x\right)}=e^0

x\:=e^0

x = 1

Thus, the point of x-intercept is: (0, 1)

<u>Conclusion:</u>

Now, if we carefully check the graph options, we can easily figure out that the first graph (top-left) correctly displays the x and y-intercepts.

It is clear from the graph that:

at x = 0, y is heading towards -ve infinity.

at y = 0, x = 1

Therefore, the first graph (top-left) is the correct graph.

Please, also check the attached graph.

I wanna know how to get this answer using the quadratic formula 4t2 + 9t − 3 = 0
motikmotik

\text{The quadratic formula is:}\\\\x=\frac{-b\pm\sqrt(b^2-4ac)}{2a}\\\\\text{In the equation, your 4 is a, 9 is b, and -3 is c}\\\\\text{Plug in and solve:}\\\\t=\frac{-9\pm\sqrt(9^2-4(4)(-3))}{2(4)}\\\\t=\frac{-9\pm\sqrt(81-4(4)(-3))}{2(4)}\\\\t=\frac{-9\pm\sqrt(81+48)}{2(4)}\\\\t=\frac{-9\pm\sqrt129}{2(4)}\\\\t=\frac{-9\pm\sqrt129}{8}\\\\\text{Since you can't simplify any further, that'll be your answer}\\\\\boxed{t=\frac{-9+\sqrt129}{8}\,\,and\,\,t=\frac{-9-\sqrt129}{8}}
