how do i solve 4x-9=k for x?
4x-9=k 4x=k+9 Divide by 4 to isolate the x x=(1/4)k+(9/4) x=1/4 k+ 9/4
An expression for 9 less than k?
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
What positive value for k would make the following the equations of a pair of parallel lines on the same coordinate axes?
First rearrange the second equation to fit the form y = mx + c, where m = slopeWe get y = (9/k) x - 7/kParallel lines have the same slope. From equation 1, slope = kFrom equation 2, slope = 9/k . Equating the two slopes we get k = 9/k; k² = 9; k = 3
What does x equal in this problem. cos(6x) sin(3x - 9)?
The solutions are:x = 11 + k*120x = 51 + k*120x = 87 + k*120where k is an integer.In the interval (0, 360) there are 9 solutions.
A line that includes the points 0 k and -6 3 has a slope of 1. What is the value of k?
Slope = (change in y)/change in x so (3 - k)/(-6 - 0) = (3 - k)/-6 = 1 3 - k = -6 3 = k - 6 3 + 6 = k k = 9 so the points are (0,9) and (-6,3) The actual formula of the line could be written as y = x + 9
