Solve the quadratic equation y2-15 equals 0?
y=±√15
What does 15--13 equal 15 --13 equals 28 because a minus and a minus equals a plus so the equation is actually 15 plus 13 equals 28?
Yes that is correct
What is the y and x intercept for the equation 3x plus 5y equals -15?
We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
What integer divided by the sum of negative 4 and positive 6 equals negative 15?
Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.
3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
What is 5y-3 equals 2y plus 12?
Y=55y-3=2y+123y-3=123y=15y=5
What is the answer5y equals 2y-12?
5y = 2y - 123y = -12y = -4
