In two or more complete sentences, explain how to use ordered pairs of points in x) = 2x + 5 and g(x)=

Naddika [18.5K]

Answer:

see the explanation

Step-by-step explanation:

we have

$A(x)=2x+5$

Find the inverse of A(x)

Let

y=A(x)

$y=2x+5$

Exchange the variables x for y and y for x

$x=2y+5$

Isolate the variable y

$2y=x-5$

$y=\frac{x-5}{2}$

Let

$g(x)=y$

$g(x)=\frac{x-5}{2}$ ------> function inverse of A(x)

Explanation

For x=1

Find the value of A(x)

$A(1)=2(1)+5=7$

The point (1,7) is a solution for A(x)

That means-----> The point (7,1) is a solution for the function inverse g(x)

Verify

For x=7

$g(7)=\frac{7-5}{2}=1$

The point (7,1) is a solution for g(x)

therefore

A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)

Question 2 Answer Solve

Lelu [443]

Answer:

Option B is correct.

Step-by-step explanation:

To subtract fractions, we must check if the denominators of both fractions are the same.

2/5 - 1/7
=> 2 x 7/5 x 7 - 1 x 5/7 x 5
=> 14/35 - 5/35

Now, let's subtract for the result.

=> 9/35

Hence, Option B is correct.

Hoped this helped.

Please need help on geometry

Doss [256]

These involve the rules for the power of a point. For questions 6-8, we use the theorem that the square of the length of the tangent is equal to the length of the secant multiplied by the length of its external segment.
6. 6^2 = (3)(x + 3)12 = x + 3x = 9 units
7. 4^2 = (2)(x + 2)8 = x + 2x = 6 units
8. 24^2 = (12)(x + 12)48 = x + 12x = 36 units
9. The included angle is half the difference of the larger and smaller arcs. Since the larger arc is 85 degrees, the smaller is 25 degrees, and the difference is 60. Half this difference is x = 30 degrees.
10. The angles at the intersection are vertical angles, so both equal to 65 degrees. Then the sum of the intercepted arcs must be equal to double of the vertical angle: 2 x 65 = 130 degrees. Since one is 95 degrees, the other is x = 130 - 95 = 35 degrees.

Anastasy [175]

Answer:

( 15m + 31 ) / ( m + 10 )

Step-by-step explanation:

add like terms

m + 14m = 15m

( 15m + 31 ) / ( m + 10 )
