What are the solutions to the simultaneous equations of 3x -y equals 5 and 2x2 plus y2 equals 129?
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
What are points of intersection of the line 3x -y equals 5 with the curve of 2x squared plus y squared equals 129?
Straight line: 3x-y = 5 Curved parabola: 2x^2 +y^2 = 129 Points of intersection works out as: (52/11, 101/11) and (-2, -11)
How do you factorise y squared plus 9y minus 52?
y^(2) + 9y - 52 # Write down all the factors of '52' Hence 1, 52 ; 2 , 26 ; 4 , 13 ; By addition or subtraction, select a pair of factors that 'add' to '9' They are, '4' & '13' ; Hence 13 - 4 = 9 Set up ther brackets , without the signs Hence ( y 4)(y 13) Since '52' is negative (-) , then the two signs are different. Since '9' is positive then the larger factor is positive(+). Hence inserting (y - 4)(y + 13) Factored!!!! Done!!!!
What is the largest integer value of x given that -52x is less than or equal to 7?
-52x <= 7 (-52x)/(-52) >= 7/(-52) {divide both sides by -52, and reverse the inequality when dividing by a negative. x >= -7/52 There is no largest integer value for x. If the question was ... greater than or equal to ... then the solution would be x <= -7/52, and the largest integer value would be -1.

What is the radius of x2 plus y2 - 10x plus 4y - 52 equals 0?
Complete the squares: x2 - 10x + 25 + y2 + 4y + 4 - 52 = 25 + 4 = 29 x2 - 10x + 25 + y2 + 4y + 4 = 52 + 29 = 81 So the radius is sqrt(81) = 9
What does 95 plus 52 plus 95 plus 52 equals?
95 plus 52 plus 95 plus 52 equals 294.
What is 8x6 plus 4 equals?
8x6 plus 4 equals 52.
What are the points of intersection when the line y equals 10x -12 crosses the curve y equals x squared plus 20x plus 12?
If: y = 10x -12 and y = x^2 +20x +12 Then: x^2 +20x +12 = 10x -12 Transposing terms: x^2 +10x +24 = 0 Factorizing: (x+6)(x+4) = 0 => x = -6 or x = -4 Points of intersection by substitution are at: (-6, -72) and (-4, -52)
68-3x equals 10x plus 16?
68-3x=10x+16 Combine like terms. (Subtract 16 from both sides. Subtract -3x from both sides.) This will give you: 52=13x Divide both sides by 13. Your answer is x=4.
