Sorry. "And" is not a mathematical operation. "3 point 3 and 7 point 7" are just
two numbers.
If you want them added, then 3.3 + 7.7 = 11 .
If you want them subtracted, then there are two results depending on the order.
3.3 - 7.7 = -4.4 and 7.7 - 3.3 = +4.4.
If you want them multiplied, then 3.3 x 7.7 = 25.41 .
If you want them divided, then the result again depends on the order.
3.3 divided by 7.7 = 3/7 (0.42857 rounded), and 7.7 divided by 3.3 = 2 and 1/3 .
Second answer: In 4th grade i remember my teacher telling me and was a . not sure that is the truth, dont trust your teachers kids, look everything you learn up to know for sure that your being taught truthfully.
(Didn't listen that closely when the subject was spelling, did ya !)

It is: y-7 = -3(x--3) => y = -3x-2
Using the point (x1, y1) = (4, -3) and the slope m = 1, we have: (y - y1) = m(x - x1) substitute the given values: (y - -3) = 1(x - 4) (y + 3) = (x - 4) this is the point-slope form of the equation of a line. y + 3 = x - 4 subtract 3 to both sides y = x - 7 this is the slope intercept form, and -x + y = -7 is the general form
Points: (-10, -3) and (7, 14) Slope: 1 Equation: y = x+7 whereas the slope is 1 and the y intercept is 7
Equation of circle: (x+2)^2 +(y+3) = 49
Point: (7, -5) Slope: -4/7 Equation: 7y = -4x-7
