PREGUNTA 6 given the polynomials fix) = 3x2+6x-1 y gix) - 1

Answers

Answer 1
Answer:

Answer:

f(x)-g(x)=x^2+9x+2

Step-by-step explanation:

f(x)-g(x)=(3x^2+6x-1)-(2x^2-3x-3)

           =3x^2+6x-1-2x^2+3x+3

           =(3x^2-2x^2)+(6x+3x)+(-1+3)

           =x^2+9x+2

30 points! Find the angles formed by two intersecting lines, if the sum of three of the four angles is equal to 270°.

Answers

One pair of vertical angles measures 90 degrees each, and the other pair of vertical angles measures 90 degrees each as well.

How to solve for the angles

When two lines intersect, they form four angles. The angles that are opposite each other, called vertical angles, are equal. The sum of the measures of the vertical angles and the adjacent angles is 180° because they form a straight line.

Solving for x we get:

2x + 180 - x = 270

x = 90

Therefore, one pair of vertical angles measures 90 degrees each, and the other pair of vertical angles measures 90 degrees each as well.

each angle is 90 degrees because 90 times 3 is 270.

why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller

Answers

Because in fractions you are taking away. For example: if you multiply 1/2 times 1/2, you are taking 1/2 away from that original half, but with whole nombers you are increasing the value. For exapmle: if you multiply 2 times 2, it will give you more.

What is the value of x?​

Answers

Answer:

120

Step-by-step explanation:

Because we know that the line opposite of the right angle is flat, we know that 60 plus x must equal 180. Rewriting this gives us 180 - 60 = x.

Now, we can just solve for x.

x = 120.
