6 persons * $8= $48
4 popcorns * $6.25= $25
6 persons * $2.75= $16.5 (drinks)

$48+$25+$16.5= $89.50 total

Two times x is 8 more than y. The sum of x and two times y is 14. Write two equations and graph to find the value of y.
Sauron [17]

Option B: $y=4$ is the value of y

Explanation:

It is given that "Two times x is 8 more than y". Writing it as expression, we have,

2x=8+y

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

x+2y=14

To find the value of y, let us solve the two equations using substitution method.

From the equation 2x=8+y , let us find the value of x.

x=\frac{8+y}{2}

x=\frac{8}{2} +\frac{y}{2}

x=4+\frac{y}{2}

Now, substituting x=4+\frac{y}{2} in the equation x+2y=14 , we get,

4+\frac{y}{2}+2y=14

      4+\frac{5y}{2} =14

            $\frac{5 y}{2}=10$

            5y=20

              $y=4$

Thus, the value of y is $y=4$

(a+2b)² ?????????????????????<br>​
lbvjy [14]

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

Rearrange each of the following in slope/y-intercept form, y = mx + b.
attashe74 [19]

Answer:

a.

{ \tt{3x - 6y + 8 = 0}} \\ { \tt{ 6y = 3x - 8}} \\ { \boxed{ \bf{y =  \frac{1}{2} x -  \frac{4}{3} }}}

b.

{ \tt{ - 2x - 5y - 2 = 0}} \\ { \tt{5y =  - 2x + 2}} \\ { \boxed{ \bf{y =   - \frac{ 2}{5} x +  \frac{2}{5} }}}
