Answer:
No
Step-by-step explanation:
Start by using the distributive property to simplify 8(1/4x+3/4):
8•1/4x=2x
8•3/4=6
The equation now reads: 2x+6-3=17. Subtract 3 from six and you get 2x+3=17.
You can now proceed to answer this like any two step linear equation.
2x+3=17
-3 -3
2x=14
x=7
7 is the solution to this equation

Answer:

Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
so

solve for x


Answer:
The functions satisfy the differential equation and linearly independent since W(x)≠0
Therefore the general solution is

Step-by-step explanation:
Given equation is

This Euler Cauchy type differential equation.
So, we can let

Differentiate with respect to x

Again differentiate with respect to x

Putting the value of y, y' and y'' in the differential equation



⇒m²-10m +24=0
⇒m²-6m -4m+24=0
⇒m(m-6)-4(m-6)=0
⇒(m-6)(m-4)=0
⇒m = 6,4
Therefore the auxiliary equation has two distinct and unequal root.
The general solution of this equation is

and

First we compute the Wronskian


=x⁴×6x⁵- x⁶×4x³
=6x⁹-4x⁹
=2x⁹
≠0
The functions satisfy the differential equation and linearly independent since W(x)≠0
Therefore the general solution is

Answer:
We just have to solve each power.

Remember, to solve a power, we just need to multiply its base as many times indicates its exponent.
It's important to know that the negative exponent indicates a position, that's why in the second exercise we needed to change the position of the power to continue.
