Question

Is (-4, 2) a solution of 4x + 5y 3-7? PLEASE HELP WILL MARK BRANLIEST

Answer 1

Please note that your equation sounds a little unclear. But, I am assuming that your equations in two ways and solving both equations.

$4x+5y^3=-7$

$4x+5y=-37$

so, I will solve both of them.

Answer:

Please check the explanation.

Step-by-step explanation:

1)

• $4x+5y^3=-7$

Assuming the equation

$4x+5y^3=-7$

substituting x = -4 and y = 2

$4\left(-4\right)+5\left(2\right)^3=-7$

$-16+2^3\cdot \:\:5=-7$

$-16+40=-7$

$24=-7$

False!

The sides are not equal!

Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of $4x+5y^3=-7$.

2)

$4x+5y=-37$

Assuming the equation

$4x+5y=-37$

substituting x = -4 and y = 2

$4\left(-4\right)+5\left(2\right)=-37$

$-16 + 10 = -37$

$-6=-37$

False!

The sides are not equal!

Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of $4x+5y=-37$.
