Option A

<u>Answer:</u>

The equation of the line parallel to x = 7, passing through the point (-4, 1) is x = -4

<u>Solution: </u>

Given that the line is parallel to x = 7 and passes through the point (-4, 1)

we have to find the equation of the line.

Step 1:

x=7 is the equation of a vertical line parallel to the y-axis.

Thus a parallel line will have equation x = c

Where c is the value of the x- coordinate the line passes through.

Step 2:

The line passes through (- 4, 1) with x- coordinate of - 4, thus

x = - 4 is the equation of the parallel line.

Result:

Thus the equation of the line parallel to x = 7, passing through the point (-4, 1) is -4.

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adult
amid [387]

Answer:

Number of children = 386

Number of adults = 287

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 673 (1)

1.75x + 2y = 1249.50 (2)

From (1)

x = 673 - y

Substitute x = 673 - y into (2)

1.75x + 2y = 1249.50

1.75(673 - y) + 2y = 1249.50

1177.75 - 1.75y + 2y = 1249.50

- 1.75y + 2y = 1249.50 - 1177.75

0.25y = 71.75

y = 71.75/0.25

y = 287

Substitute y = 287 into (1)

x + y = 673

x + 287 = 673

x = 673 - 287

x = 386

Number of children = 386

Number of adults = 287
