x/2 + 7
5 it is 5 because 13 + 7 = 20 20 divided by 4 is 5 to find out the answer, work through the equation backwards and use the opposite operations.
Slope: -13 Point: (5, 7) Equation: y = -13x+72 whereas -13 is the slope and 72 is the y intercept
Slope: -13 Point: (5, 7) Equation: y = -13x+72 whereas -13 is the slope and 72 is the y intercept
y - 7 = -13(x - 5)apexvs
13
Equation of circle: (x-3)^2 +(y+5)^2 = 13
Centre of circle: (3, -5) Distance from (3, -5) to (6, -7) is the square root of 13 which is the radius Equation of the circle: (x-3)^2 + (y+5)^2 = 13
If you mean: slope of -13 and point of (5, 7) then the equation is y = -13x+72
Well since an equation has an equal sign it is 6+7=13
n - 13 = 7
The answer is -7.This is how I solved it:-5j-13=22 taking away (subtracting) 13, is the same as adding a negative13, in algebra, you never subtract, you add negatives instead, so first you change your original equation to this:-5j + -13=22 in algebra, this type of equation is called a 2-step equation. Anyways next you add the opposite of your lonesome number(number without a variable), in this case being the -13, to both sides of the equation. What I mean bt this, is if you have a -13, you add a +13 to BOTH sides of the = sign like this:-5j +(-13 + 13)=22+13 ---> -5j=35 (no need to say + 0) so now that you have that done, you must divide both sides of the equation by the variable term, DON'T FORGET WHETHER IT'S POSITIVE OR NEGATIVE!!! like this(this is just for this specific equation):-5j=35-------- J=-7 the -5 cancels out and 35/-5 =-7, so J=-7 Hope I helped :-)-5 -5
13 + a + 7 = 5 + b - 20. This assumes the two numbers are different.
