Let ​ f(x)=x+2 ​ and ​ g(x)=2x+1 ​ .
gogolik [260]
<h2>x= 0 and x= 1</h2>

Step-by-step explanation:

Given  g(x) = x+2  and   f(x) = 2^x+1

If f(x) = g(x)

⇔2^x+1 = x+2

⇔2^x= x +1

Only x= 1 and x=0 will be satisfy  the above equation.

If x= 1, it gives             and x=0 gives

2^1= 1+1                       2^0=0+1

⇔2=2                          ⇔1=1

What is the image point of (4, 6) after the<br> transformation T5,2 O ry=-x?
nirvana33 [79]

Answer:

The image point is (-1,-2)

Step-by-step explanation:

Firstly, we have to reflect the given point over the line y = -x after which we perform the translation using the coordinate (5,2)

Mathematically;

If we reflect a point (x,y) over the line y = -x

we have the coordinate change to (-y,-x)

so, (4,6) becomes (-6,-4)

Then for the translation, we add 5 to the new x-axis coordinate, then add 2 to the new y-axis coordinate

we have this as;

(-6 + 5, 2-4) = (-1,-2)
