Simplify the following expression by combining like terms.

Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x

What is the solution to the system of equations. 2x-y=7 y=2x+3

OLEGan [10]

To solve this, you can substitute the second equation into the first.

It becomes 2x-(2x+3)=7

Solve from here!

You get -3=7. Not possible. Therefore there is no solution to this system.

System is inconsistent. Hope this helps.

in base ten, the two-digit prime N is 45 more than the number formed by reversing the digits of N, find all the possible values

Drupady [299]

Let $N=10x+y$ , so that $x$ is the digits in the tens place and $y$ is the digit in the ones place. (Clearly $x\neq0$ .)

$10x+y=45+10y+x\implies 9x-9y=45\implies x-y=5$

There are five possible two digits integers that satisfy this relation:

$x=5,y=0\implies N=50$
$x=6,y=1\implies N=61$
$x=7,y=2\implies N=72$
$x=8,y=3\implies N=83$
$x=9,y=4\implies N=94$

But the first, third, and fifth candidates are even, so they are not prime. The remaining are prime, however, so $N=61$ or $N=83$ .
