Write the percent as a fraction in lowest terms: 65% Use the percent proportion to solve the problem: What number is 95% of 70?
Use the percent proportion to solve the problem: 8 is 25% of what number?
Use the percent proportion to solve the problem: 60 is 75% of what number?
For a relation (3, 5), (4, 7), and (5, 9), what are the input values?
Is the relation (3, 5), (4, 7), and (5, 9) also a function? Explain.
Is the relation (2, 1), (2, 5), (4, 9) also a function? Explain.
Is the ordered pair (2, -3) a solution of the equation y = 3x - 9?
Is the ordered pair (5, 4) a solution of the equation 4x + 5y = 40?
Is the ordered pair (5, 2) a solution of the equation 3x + 4y = 29?
Find the x-intercept of the equation 3y - 9x = 27
Find the y-intercept of the equation 5y - 25x = 30
Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Write the equation in function form (solved for y alone)
2y - 8x = 6.
What is the slope of the line y = 3x + 2
What is the slope of the line 4x - 20x = 8
What is the slope of the line that passes through the points (1, 2) and (3, 12)?
