Answer:

x=(0.45,-4.45)

Step-by-step explanation:

x²+4x=2

x²+4x+(2)²=2+(2)²

x²+(2)²=2+4

(x+2)²=6

√(x+2)²√6

x+2=√6

x=-2±√6

x=-2±2.45

x=(0.45,-4.45)

Answer:

A.) 2x - 9x - 30 = -6

Step-by-step explanation:

hello !

to solve this system of equations, first, we substitute the equation $y = 3x + 10$ to the <em>y </em>variable in the equation $2x-3y = -6$ . Therefore, we get:

$2x - 3(3x+10)=-6$

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

$2x - 9x - 30 = -6$

Given the functions f(x) = 3x − 1 and g(x) = 3x + 4, which operation results in the smallest coefficient on the x term?

Vera_Pavlovna [14]

Division because if you divide the two functions together, you keep the 3 in the x term. If you add the two functions, your coefficient is 6. If you subtract, the x term is eliminated. If you multiply, you'll get 9x.
3 is smaller than 6 or 9 :)
