To simplify the expression 13x + 2y - 10x - 7y, you first combine like terms. Group the x terms together and the y terms together: (13x - 10x) + (2y - 7y). This simplifies to 3x - 5y. Therefore, the simplified expression is 3x - 5y.
(13x)2 = 169x2
13x-14 or 13x+(-14)
2x2 - 13x - 7 = (2x + 1)(x - 7)
13x 32 plus 5x can be expressed mathematically as 173x/32.

i am guessing here that this is what you mean as it involves substitution: 2x-2y = 4 therefore -2y = 4 - 2x Sub the above line into the first equation gives: 13x - 2x +4 = 70 11x = 66 x=6 then sub in x 13(6) - 2y = 70 78 - 2y = 70 y=4 Yep, this is the exact same as simultaneous equations
Points: (7, 3) and (-6, 1) Midpoint: (0.5, 2) Slope: 2/13 Perpendicular slope: -13/2 Perpendicular equation: y-2 =-13/2(x-0.5) => 2y-4 = -13x+6.5 => 2y = -13x+10.5 Therefore the perpendicular bisector equation is: 2y = -13x+10.5
There can be no answer because the question contains an expression, not an equation or inequality.
Points: (7, 3) and (-6, 1) Midpoint: (0.5, 2) Slope: 2/13 Perpendicular slope: -13/2 Equation: y-2 = -13/2(x-0.5) => 2y-4 = -13(x-0.5) => 2y = -13x+10.5 Perpendicular bisector equation in its general form: 13x+2y -10.5 = 0
A1: 7x-4y=9 , 3x+2y=15 and 7x-4y=9, 6x+4y=30 so 13x=39 x=3 now plug it in for y 9+2y=15 so y=3 A2: The right expression is missing a + or - between the 3x and 2y. For the purpose of this demo, let's assume it is 3x+2y-15. It can be solved by multiplying the right expression by 2, then add the expressions. That will eliminate y. Then solve for x. When x is known, plug its value into either of the expressions and solve for y. To start: 2(3x+2y-15)=6x+4y-30 adding the two (7x-4y-9)+(6x+4y-30)=13x+0y-39=13x-39 solve for x
Points: (7, 3) and (-6, 1) Midpoint: (0.5, 2) Slope: 2/13 Perpendicular slope: -13/2 Perpendicular equation: y-2 = -13/2(x-0.5) => 2y-4 = -13x+6.5 => 2y = -13x+10.5
13x-11y-12 11 11 13x-1 -13x-13x=12
13x
13x - 4x = 9
13x-10x = 3
