If you'd estimate the numbers, it would be $3500÷700. Because if you look at the tenths place, if the number is higher than 5, than the first digit goes up.
$3500÷700=5
Im not very good at explaining.
Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
Answer:
Every polynomial with rational coefficients has the same roots as one with integer coefficients; just multiply through by the common denominator. The complex roots of such polynomials come as conjugate pairs.
