Twenty, which is 4 more than half, of the students in Bryan’s homeroom have tickets to attend the school’s musical. Choose Yes o

Ad libitum [116K]

Answer:

$4-\frac{1}{2}m=20$ ......No

$\frac{1}{2}m+4=20$ .......Yes

$\frac{1}{2}m-4=20$ .....No

$4=20-\frac{1}{2}m$ ......Yes

Step-by-step explanation:

Let the number of students in Byran's homeroom who have tickets to attend the school's musical be m.

Then 4 more than half this number is written as: $\frac{1}{2}m+4$

According to thee given statement, this expression is equal to 20.

$\frac{1}{2}m+4=20$

We can subtract $\frac{1}{2}m$ from both sides to create an equivalent expression.

$4=20-\frac{1}{2}m$

Write an equation of the line that is perpendicular to 3x + 9y = 7 and passes through the point (6, 4)

andrezito [222]

The perpendicular line will have the x and y coefficients swapped and one of them negated. We can write the desired line as
9(x -6) -3(y -4) = 0
where the coordinates of the point of interest are (6, 4).
Dividing by 3, this is
3(x -6) -(y -4) = 0
3x -y = 14

An equation for the line of interest is ...
3x -y = 14
