Explain why the equation x+2=x+3 has no solution

Orlov [11]

It has no solution because x is always the same amount. So.. for example.
lets say x = 10.

then it would be 10 + 2 = 10 + 3.
12 doesnt = 13. :)

Which points are on the graph of the equation - 3x + 6y + 5 = -7?

ludmilkaskok [199]

Answer:

C and E

Step-by-step explanation:

To solve this problem, let's plug in each coordinates into the equation.

$-3(-3) + 6(6) + 5 = -7$
$9 + 36 + 5 = -7$
$50 = -7$
$50 \neq -7$
A. cannot be the answer, as 50 does not equal -7.

$-3(-2) + 6(0)+5=-7$
$6+0+5=-7$
$11=-7$
$11\neq -7$
B. cannot be the answer, as 11 does not equal -7.

$-3(0) + 6(-2) + 5 = -7$
$0 - 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
C. can be the answer, as -7 does equal -7.

$-3(6)+6(-3)+5=-7$
$-18-18+5=-7$
$-36+5=-7$
$-31\neq -7$
D. cannot be the answer, as -31 does not equal -7.

$-3(8) + 6(2) + 5 = -7$
$-24 + 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
E. can be the answer, as -7 does equal -7.
