Solve the following system using ANY method.

Mathematics
1 answer:
creativ13 [48]3 years ago
4 0

Answer:

a=-2 and b=-9

Step-by-step explanation:

To solve the system, substitute one equation into another.

8a -4b = 20 becomes -4b = 20 - 8a. Dividing by -4 on both sides, b = 2a-5.

Now substitute the equation b=2a-5 into 5a - 8b = 62.

5a - 8(2a-5) = 62

5a - 16a + 40 = 62

-11a + 40 = 62

-11a = 22

a=-2

To find b, substitute a=-2 into b=2a-5.

b = 2(-2) - 5

b = -4 - 5

b = -9

Verify if f(x)= 5-3x/2 and g(x)= 5-2x/3 are inverses. Please show step by step.
mestny [16]

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.

<h3>Inverse of functions</h3>

In order to determine if the function f(x) and g(x) are inverses of each other, the composite function f(g(x)) = g(f(x))

Given the function

f(x)= 5-3x/2 and

g(x)= 5-2x/3

f(g(x)) = f(5-2x/3)

Substitute

f(g(x)) = 5-3(5-2x)/3)/2

f(g(x)) = (5-5+2x)/2

f(g(x)) = 2x/2

f(g(x)) = x

Similarly

g(f(x)) = 5-2(5-3x/2)/3

g(f(x)) = 5-5+3x/3

g(f(x)) = 3x/3

g(f(x)) =x

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.
