Answer:

x = 20
y = 114°

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the remote interior angles.

(3x +6)° = 31° +35°

3x +6 = 66 . . . . . . . . . . divide by °, collect terms

3x = 60 . . . . . . . . subtract 6

x = 20 . . . . . . . divide by 3

The value of y is the supplement of (3x+6)°, and of the sum (31 +35)°.

y = 180° -66° = 114°

The values of x and y are 20 and 114°, respectively.

The volume of a cube, in cubic centimeters, is given by the function V(x) = x3, where x is the side length of the cube in centim

Sav [38]

I think we can all agree that 1 centimeter=10millimeters.

And if x is the side in centimeters then 10x will be the side in millimeters.

We just need to rewrite x^3 into (10x)^3.

Because you need to do the exponent to all part of the ( )...

(10x)^3=1000x^3

V(x)=1000x^3 cubic millimeters is the answer

Please help problems below!!!

Delvig [45]

Answer:

#16 has the greatest y - intercept,

Step-by-step explanation:

the y - intercept is the number that comes after x in y = ?x + ?

The equation is y = mx + b, where m is the slope and b is the y - intercept.

#13 has a y - intercept of 5, #14 has 0, #15 is 2, and #16 is 6

The y - intercept is the value of y when x is 0, or where the line is on the y -axis

Quadratic Formula: $\displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Algebra II

Imaginary Numbers: √-1 = i

Step-by-step explanation:

Step 1: Define

x² + 2x = -2

Step 2: Identify Variables

Rewrite Quadratic in Standard Form [Addition Property of Equality]: x² + 2x + 2 = 0
Break up Quadratic: a = 1, b = 2, c = 2

Step 3: Solve for x

Substitute in variables [Quadratic Formula]: $\displaystyle x=\frac{-2 \pm \sqrt{2^2-4(1)(2)}}{2(1)}$
[√Radical] Evaluate exponents: $\displaystyle x=\frac{-2 \pm \sqrt{4-4(1)(2)}}{2(1)}$
Multiply: $\displaystyle x=\frac{-2 \pm \sqrt{4-8}}{2}$
[√Radical] Subtract: $\displaystyle x=\frac{-2 \pm \sqrt{-4}}{2}$
[√Radical] Factor: $\displaystyle x=\frac{-2 \pm \sqrt{-1}\sqrt{4}}{2}$
[√Radicals] Simplify: $\displaystyle x=\frac{-2 \pm 2i}{2}$
Factor: $\displaystyle x=\frac{2(-1 \pm i)}{2}$
Divide: $\displaystyle x = -1 \pm i$
