What is the solution to the following equation? (4 points) 2(3x − 7) + 18 = 10
konstantin123 [22]

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*(3*x-7)+18-(10)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(2 • (3x - 7) + 18) - 10 = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

6x - 6 = 6 • (x - 1)

Equation at the end of step 3 :

6 • (x - 1) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 6 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : x-1 = 0

Add 1 to both sides of the equation :

x = 1

One solution was found :

x = 1

All of the following are epuivalent forms 9/11 except
meriva

Answer: Except (4) but see detail below

Precisely speaking, \frac{9}{11}=0.\overline{81}=0.818181....

Looking over the choices, only 72/88 = 9/11 is precisely "equivalent" so all of (1), (2), and (4) would be EXCEPT.

But because K12 teachers' language may sometimes be sloppy,  "equivalent"  may also mean "approximate." If that is the case (I let you make the call if the premise is true): the following are definitely not 9/11:

1.22  (is greater than 1)

It could also be that the original question had the "overline" mark to mean "periodic" over the 81 parts, like this:

0.\overline{81}\\0.\overline{8181}

which then means they are equivalent, leaving truly only 1.22 is the one non-match

Step-by-step explanation:

y=a(x-h)^2+k

This gives the parabola in vertex form

(h,k) is the vertex where h is the x coordinate and k is the y coordinate

k is the vertical shift
