- Write the standard form of the equation of the circle with center (5, -7) and radius 5.
- Determine whether the equation -6(x+3)=-6x-18 is an identity, contradiction, or conditional equation. If conditional, indicate the condition. Explain your reasoning.
- A room is 2.5 as long as it is wide, and its perimeter is 15 meters. Write l in terms of w and write an equation for the perimeter in terms of w.
- Find the slope and y-intercept (if possible) of the equation of the line. 3x-5=0
- Find the value of y that corresponds to x = -4 in the graph of the equation 2x+3y=13.
- Write the slope-intercept form of the equation of the line through the given point perpendicular to the given line. point: (-4, 9) line: 6x – 30y = 6
- Identify any intercepts and test for symmetry. Then sketch the graph of the equation
Y =x^2 -4x
