Answer:
Equation 1: x-3y+5=0
Equation 2: 3x+y-1=0
Step-by-step explanation:
Equation 1: x+3y=-5
x+3y+5=-5+5
x=3y+5=0
Equation 2: 9x+3y-3=0
3x+y-1=0
18 is an even number because if you divide 18 ÷ 2 = 9 it guves you an odd number
Answer:
In the Pythagorean Theorem, a right triangles hypotenuse is found by a^2 +b^2= c^2. The distance formula is basically the same thing. With two points, a right triangle can be formed and the slop would be the hypotenuse. That's where the distance formula comes from
Step-by-step explanation:
Answer:
there would be about 5/6 chance
Step-by-step explanation:
We can use the system of equations:x + y = 217x - y = 85-----------------From the 2nd equation: y = x - 85x + x - 85 = 2172 x = 217 + 852 x = 302x = 302 : 2x = 151y = 217 - 151y = 66We can prove this solution:151 + 66 = 2017 and 151 - 66 = 85.Answer: those numbers are 151 and 66.
