How many solutions for x does the following equation have? 2(x + 4) − 1 = 2x + 7

Mathematics
1 answer:
4vir4ik [10]3 years ago
8 0

Answer:

The equation has infinity solutions

Step-by-step explanation:

we have

2(x+4)-1=2x+7

Applying distributive property left side

2x+8-1=2x+7

Combine like terms

2x+7=2x+7

The linear equation of the left side is equal to the linear equation of the right side

Both lines are identical

therefore

Is a consistent dependent system

The equation has infinity solutions

7. Find DE.<br> 11-25<br> E<br> А<br> 4x + 1<br> D<br> С
Arlecino [84]

Answer:

  • DE = 37

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

  • 4x + 1 = 1/2(11x - 25)
  • 2(4x + 1) = 11x - 25
  • 8x + 2 = 11x - 25
  • 11x - 8x = 2 + 25
  • 3x = 27
  • x = 27/3
  • x = 9

DE = 4*9 + 1 = 36 + 1 = 37

What is the domain of the function represented by the graph? A graph shows an upward parabola on a coordinate plane vertex at (m
vlabodo [156]

Using it's concept, the domain of the function represented by the graph is all real numbers.

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function.

In this problem, a parabola is used, which has no restriction such as an even root or a fraction, hence the domain is all real values.

Do I agree or disagree
9966 [12]
You disagree because you cannot write that number as a fraction since there is no number in the ones place when it is solved and turned into a decimal.
