What is the algebraic expression of a quotient of a number Y and seven?
y divided by 7 is y/7 7 divided by y is 7/y
What is the value of y - 4 when y equals -7?
11
How do you solve y squared plus 14y plus 49?
(y + 7).(y + 7) = zeroy + 7 = zeroand so y = -7
What number multiplies by 7 and adds 25 to equal 165?
y*7+25=165 y*7+25-25 = 165-25 y*7+ 0 =140 y*7/7 = 140/7 y=20
What two numbers added together make7 but multiplied make 20?
Let call them x and y x+y=7 and x*y=20 From the first you get x = 7 -y, put into the second get (7-y)*y=20 -y^2+7*y=20 or y^2-7+20=0 Delta = (-7)^2-4*1*20 = -31 y = (7-i*sqrt(31))/ 2 or y = (7+i*sqrt(31))/ 2 and x = 7-y = (7+i*sqrt(31))/ 2 or x = (7-i*sqrt(31))/ 2
