Answer:

y = 2x + 3

Step-by-step explanation:

Get any two points on the line, say (0, 3) and (2, 7)

Slope = (7 - 3)/(2 - 0) = 4/2 = 2

y = 2x + b

use (0, 3), x = 0, y = 3

3 = b

so the equation is y = 2x + 3

X^6+3x^3-5 <br> write the expression in quadratic form

Art [367]

Step-by-step explanation:

$v = {x}^{3} \\ {v}^{2} + 3v - 5 = 0 \\$

Solving this equation using the quadratic formula, we get two real solutions :

1.1926 or -4.1926

Now we know the values of v , we can calculate x since x is ∛ v

${x}^{6} + 3 {x}^{3} - 5 = 0$

$x = \sqrt[3]{1.1926} = 1.0605 \\ x = \sqrt[3]{ - 4.1926} = - 1.6125$
