What is the equation of x

Mathematics
2 answers:
Bas_tet [7]2 years ago

Answer: -9.6

Step-by-step explanation: First, you combine like terms, making the equation 5x +7 = -41. Then you need to isolate the variable by subtracting 7 from both sides which makes your equation 5x = -48. Then you divide both sides by 5, which isolates x, and gives you a final answer of x = -9.6

LenKa [72]

Answer:

27%

Step-by-step explanation:

If the function h is defined by h(x)=<img src="https://tex.z-dn.net/?f=x%5E%7B2%7D" id="TexFormula1" title="x^{2}" alt="x^{2}" a
harkovskaia [24]

Given:

The function is:

h(x)=x^2-3x+5

To find:

The value of h(2x+1).

Solution:

We have,

h(x)=x^2-3x+5

Putting x=2x+1, we get

h(2x+1)=(2x+1)^2-3(2x+1)+5

h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5

h(2x+1)=4x^2+4x+1-6x-3+5

On combining like terms, we get

h(2x+1)=4x^2+(4x-6x)+(1-3+5)

h(2x+1)=4x^2-2x+3

Therefore, the required function is h(2x+1)=4x^2-2x+3.
