What is the perimeter of a triangle 7x plus 9w 2x plus 8y 2y plus 5w?
The perimeter of a triangle is the sum of the lengths of the three sides.If the three expressions in the question are in fact the lengths of thethree sides, then the perimeter is their sum.(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w
What equation of the line that contains the points -3 and 2 and 5 and -5?
Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0
What is the answer to 4x plus y equals 9 and 7x-8y equals 6?
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
If x equals 4 and y equals 1 then 7x plus 8y equals?
36..thats very simple..lol
