Consider this algebraic expression: –3x + x + 5 Use the algebra tiles to model the expression.

luda_lava [24]

For this case, we have the following expression:

$-3x + x + 5$

We simplify the expression:

If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that $-3x + x = -2x$

So, we have to:

$-3x + x + 5 = -2x + 5$

Answer:

-3x + x + 5 = -2x + 5

Line M passes through the points (5,1) and (8,6) while line n passes through the point (-4,3) and (-1,8) . Which statement accur

kirill [66]

M=(6-1)/(8-5)=5/3

y=5x/3+b, using (5,1)

1=25/3+b

b=-22/3

y=(5x-22)/3

...

m=(8-3)/(-1--4)=5/3...

y=5x/3+b, using (-1,8)

8=-5/3+b

b=29/3

y=(5x+29)/3

Since they have the same slope and difference y-intercepts they are parallel lines and will never intersect.
