Answer:

x=6\frac{2}{3}

Step-by-step explanation:

Right angles always add up to 90°. You can tell it's a right-angle because of that square in the corner.

Anyway, the two angles should add up to 90°. So set up your equation:

70° + 3x = 90°

3x = 90 - 70

3x = 20

x = 20/3

x=6\frac{2}{3}

Which graph does NOT represent a function?<br> R
vredina [299]

Answer:

The graph of the circle

Step-by-step explanation:

A function is defined to have only one output per input. Conducting the horizontal line test, we see that there are instances where the line intersects two points, which shows that some inputs have multiple outputs.

This does not fit the definition of a function.

I hope this helps! :)

Which of the following is a solution to the equation 0=x2+6x+4 ?
Llana [10]

Answer:

A

Step-by-step explanation:

Given

x² + 6x + 4 = 0 ( subtract 4 from both sides )

x² + 6x = - 4

Solve using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = - 4 + 9, that is

(x + 3)² = 5 ( take the square root of both sides )

x + 3 = ± \sqrt{5} ( subtract 3 from both sides )

x = - 3 ± \sqrt{5} , thus

x = - 3 - \sqrt{5} → A

x = - 3 + \sqrt{5}
