Which of the following equations has infinitely many solutions? A. 2x + 5(2x + 6) = 12x + 30 B. 2x + 5 = 2 C. 2(x + 5) + 2 = 6x

Nat2105 [25]

Answer:

A. 2x + 5(2x + 6) = 12x + 30

Step-by-step explanation:

Infinitely many solutions means the two sides of the equation will be equal to each other, so B and D can be eliminated. Distribute for A and C to check

A. 2x + 5(2x + 6) = 12x + 30

2x + 10x + 30 = 12x + 30

12x + 30 = 12x + 30

C. 2(x + 5) + 2 = 6x + 2(x + 2)

2x + 10 + 2 = 6x +2x + 4

2x + 12 = 8x + 4

You only get the same equation for A, therefore A is the correct answer

A realator makes a commison of 3500 on a 50000 house what is commison rate

vredina [299]

Do find the commission rate, we'll use 'p' to represent the commission percent.

50000p = 3500

p = 3500/50000

We can simplify:

p = 700/10000

= 7/100

7/100 is 7%, so:

The commission rate is 7%

(1 point) Suppose that f(x) and g(x) are given by the power series f(x)=6+7x+3x2+5x3+⋯ and g(x)=7+8x+3x2+4x3+⋯. By multiplying p

dusya [7]

Answer:

f(x).g(x) = c0+c1x+c2x2+c3x3+⋯.

$f(x).g(x) = 42 +97x +95x^{2} + 104x^{3} +77x^{4} +27x^{5} + 20x^{6}+....$

c₀ = 42 , c₁ =97 , c₂ = 95, c₃ =104, ...…...

Step-by-step explanation:

Suppose that f(x) and g(x) are given by the power series

f(x)=6+7x+3x2+5x3+⋯ and

g(x)=7+8x+3x2+4x3+⋯

By multiplying power series ,

f(x).g(x) = (6+7x+3x2+5x3+⋯).(7+8x+3x2+4x3+⋯)

= 6(7+8x+3x2+4x3+⋯)+7x(7+8x+3x2+4x3+⋯)+3x2(7+8x+3x2+4x3+⋯) + 5x3(7+8x+3x2+4x3+⋯)+......

$f(x).g(x) = 42 +97x +95x^{2} + 104x^{3} +77x^{4} +27x^{5} + 20x^{6}+....$

f(x).g(x) = c0+c1x+c2x2+c3x3+⋯.is the form

$f(x).g(x) = 42 +97x +95x^{2} + 104x^{3} +77x^{4} +27x^{5} + 20x^{6}+....$

c₀ = 42 , c₁ =97 , c₂ = 95, c₃ =104, ...……
