∑ Hey, richiebustamante90 ⊃

Answer:

x = -8 or x = 2

Step-by-step explanation:

<u>→ Given ← :</u>

|3 + x| = 5

<u>→ Solution ← :</u>

Applying absolute rule ~:  \mathrm{If}\:|u|\:=\:a,\:a > 0\:\mathrm{then}\:u\:=\:a\:\quad \mathrm{or}\quad \:u\:=\:-a

Thus we have;    3+x=-5\quad \mathrm{or}\quad \:3+x=5

Solving each:

3+x=-5

3x-3=-5-3

x=-8

3+x=5

3-3+x=5-3

x=2

Hence, x=-8\quad \mathrm{or}\quad \:x=2

Answer:

x = - 8 , x = 2

Step-by-step explanation:

the absolute value function always gives a positive result, however, the expression inside can be positive or negative, , that is

x + 3 = 5 ( subtract 2 from both sides )

x = 2

or

-(3 + x) = 5

- 3 - x = 5 ( add 3 to both sides )

- x = 8 ( multiply both sides by - 1 )

x = - 8

Answer:

see below

Step-by-step explanation:

When we add fractions with the same denominator (bottom), we do not add the denominator, we keep it the same.  We only add the numerator (top)

1/2 + 1/2 = 2/2  =1

You will have given the entire sandwich away.

Me QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR?
maks197457 [2]

We write the equation in the form of directional.

y -1 = 6x               ⇔    y = 6x + 1

y - 1 = 3x              ⇔    y = 3x + 1

y - 7 = 2x - 6         ⇔    y = 2x - 6 + 7

                                    y = 2x + 1

y - 7 = x - 2           ⇔    y = x - 2 + 7

                                    y = x + 5

Equations cleverly arranged .

Point Q = (0,1)  

b factor , not only fits the last equation

In the drawing have engraved points Q and R are tangent linear function appropriate to that point . This graphics solution . y = 3x + 1

Answer b

We check choice by the system of equations , where substitute wartoćsi points Q and R to the model equations linear function

The result of equations confirmed our choice Answer b

How many home runs did each player hit the season
olya-2409 [2.1K]
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)

Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8

Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
