Answer:
1. x=3 x=1
2. x=0
Step-by-step explanation:
We want f(x) to equal g(x)
f(x)=g(x)
1/(x-2) = (x-2)
Using cross products
1 = (x-2) * (x-2)
1 = x^2 -2x-2x+4
Subtract 1 from each side
1-1 = ^2 -2x-2x+4-1
0 = x^2 -4x+3
Factoring
What number multiplies to 3 and adds to -4
-3*-1 = 3
-3+-1 = -4
0= (x-3) (x-1)
Using the zero product property
x-3 =0 x-1=0
x=3 x=1
2. f(x)=x^2+4x+2
g(x)=(1/2)^ x+1
From the graph,we can see they intersect at x=0
-1/8 is your answer
hope this helps
Answer:
second one
Step-by-step explanation:
Answer:
Let the width of the Rectangle be x inches
Then, length is (3x-5) inches
Perimeter of the Rectangle= 46 inches (given)
According to the above problem,
Equation :---- Perimeter=2(length+breadth)
<u>2{(3x-5)+x}=46</u>
2(4x-5)=46
(4x-5)=46/2=23
4x=(23+5)=28
x=28/4
<u>x=7</u>
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
