For example, 52 is not the same as 52 mph or 52 miles per hour. Find the x-intercept and the y-intercept. Write the coordinates of each intercept ) 9 )
Solve the equation for y in terms of x: 2. x – 2y = 7
y = x 2 7 2 Solve the equation for x: 3. 7x + 2 = 3x – 9 4 x + 2 =− 9 4 x =− 11 x = 11 4 Perform the indicted operation and express the result as a simplified complex number: 4. (2 + 3i)(4 – i) 2 4 + 2 ( ) + 3 4 + 3 i ( ) 8 2 i + 12 i 3 i 2 8 2 i + 12 i 3 1 8 2 i + 12 i + 3 11 + 10 i Solve the equation involving absolute value. 5. |2x + 1| - 2 = -3 Solve the following: 6. If we rent a truck and pay a $75/day fee plus $0.20 for every mile we travel, write a linear equation that would express the total cost y, using x to represent the number of miles we travel.
