complete verified solutions
Solve the Equation
x/5 = x/6 +2 - answer x = 60
First, write the value(s) that make the denominator(s)
zero. Then solve the equation.
3/x-4 + 1 = 2/x-4 - answer x = 3
Perform the indicated operations and write the result in
standard form
(5 + i)^2 - (4 - i)^2 - answer 9 + 18i
Divide and express the result in standard form
7 - 7i / 4 + 3i - answer 7/25 - 49i/25
Perform the indicated operations and write the result in
standard form
square root -49 + square root -81 - answer 16i
, Solve the equation using the quadratic formula
x^2 + 3x + 1 = 0 - answer { -3 + square root , -3 -
square root }
Solve the equation by the square root property
(x - 6)^2 = 49 - answer { -1, 13 }
Solve the radical equation, and check all proposed
solutions
square root x + 1 = 7 - answer x = 48
Give the domain and range of the relation
{ (10, -3), (5, 7), (-6, 9), (-6, -4) } - answer D: {10,5,-6}
R: {-3,-7,9,-4}
Use the given conditions to write an equation for the line
in point-slope form:
Slope = 3, passing through (8,4) - answer y - 4 = 3(x - 8)
Use the given conditions to write an equation for the line
in the slope-intercept form:
