Which of the following statements is equivalent to 10x – 30? 10(x – 30) 10(x – 3) 10 + (x – 20) 10(x – 20)
givi [52]

Answer:

10(x-3) is equivalent to 10x – 30

Step-by-step explanation:

<u>First you have to take everything of out the parentheses and then simplify if needed.  </u>

  • 10(x – 30) is not equivalent to 10x – 30 because, 10 times x is 10x, but 10 times 30 is 300. So, 10(x – 30) is not equivalent to 10x – 30.

  • 10(x – 3) is equivalent to 10x – 30 because, 10 times x is 10x, and 10 times 3 is 30. So, 10(x – 3) is equivalent to 10x – 30.

  • 10 + (x – 20) is not equivalent to 10x – 30 because, 10 minis 20 plus x are -10 + x. So, 10+(x – 20) is not equivalent to 10x – 30.

  • 10(x – 20) is not equivalent to 10x – 30 because, 10 times x is 10x, but 10 times 20 is 200. So, 10(x – 20) is not equivalent to 10x – 30.

Answer: 10(x-3) is equivalent to 10x – 30

The function ƒ is defined by ƒ(x) = (x + 3)(x + 1). The graph of ƒ in the xy-plane is a parabola. Which interval contains the x-
Inga [223]

Answer:

All the intervals that contain the number -2 are solution of the problem

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

f(x)=a(x-h)^{2}+k

where

(h,k) is the vertex of the parabola

In this problem we have

f(x)=(x+3)(x+1)

Convert to vertex form

f(x)=x^{2}+x+3x+3

f(x)=x^{2}+4x+3

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)-3=x^{2}+4x

Complete the square. Remember to balance the equation by adding the same constants to each side.

f(x)-3+4=x^{2}+4x+4

f(x)+1=x^{2}+4x+4

Rewrite as perfect squares

f(x)+1=(x+2)^2

f(x)=(x+2)^2-1 -------> equation in vertex form

The vertex is the point (-2,-1)

The x-coordinate of the vertex is -2
