Andy since 78/15 is more then 2 and more then 4.8
Answer
Option 2, 4 and 5 :)
Step-by-step explanation:
Option 2 is already simplified to 20x + 30y
Option 4,
10*2x=20x and 10*3y= 30y so option 4 also simplifies to 20x + 30y
Next Option 5, 10*2x= 20x and 10*3y=30y. So it's also 20x + 30y
Answer:
(4,-3)
Step-by-step explanation:
The y coordinate stays the same, and the x changes from positive to negative
Answer:
x-√6
Step-by-step explanation:
Non-integer powers of the variable disqualifies the expression from being a polynomial. √x -6 has x to the 1/2 power, so that expression is not a polynomial. Polynomials may have any real or complex, rational or irrational coefficients. (We usually study only polynomials with real coefficients.)
x-√6 is a polynomial
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
-------------------------------------
2x + y = -3 <em>subtract 2x from both sides</em>
y = -2x - 3
-2y = 6 + 4x
-2y = 4x + 6 <em>divide both sides by (-2)</em>
y = -2x - 3
We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions
x ∈ R
y = -2x - 3
