Answer:

g(x)=-4x+9

Step-by-step explanation:

So we know that:

f(x)=4x+9

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

g(x)=f(-x)=4(-x)+9

Simplify:

g(x)=-4x+9

And that's our answer :)

The equation(function):10.00+.75x
valentinak56 [21]

Answer:

Answer:

b. -75x+57=-75x+57

Step-by-step explanation:

If an equation after solving does not give the solution but give a true statement then the equation has infinitely many solution,

In option a.

57x+57=-75x-75

57x + 75x = -75 - 57

132x = -132

⇒ x = -1

i.e. it has only one solution,

In option b.

-75x+57=-75x+57

-75x + 75x = 57 - 57

0 = 0  ( True )

i.e. it has infinitely many solution.

In option c.

75x+57=-75x+57

75x + 75x = 57 - 57

150x = 0

⇒ x = 0

i.e. it has only one solution,

In option d.

-57x+57=-75x+75

-57x + 75x = 75 - 57

18x = 18

⇒ x = 1

i.e. it has only one solution.
