Answer:

x=-1

Step-by-step explanation:

if I understand correctly, you need to find where x^2 + 4x + 8 is equal to 2x+7, so basically where they intersect, and you must do it without calculations

in the table there is just one value of x for which the value of both y for both equations is the same and it is x = -1

The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below:
Kazeer [188]
Answer: The correct answer is the last choice.

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words it didn't move.

In the last segment, it moved up again for 2 hours.

Write the equation of the line that passes through the point (3,5) and is perpendicular to the line y=3.
3241004551 [841]

Answer:

x = 3

Step-by-step explanation:

y = 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (3, 5) with x- coordinate 3 , thus

x = 3 ← equation of perpendicular line
