Answer:
Step-by-step explanation:
Multiply the denominators so you will have common denominators.
Then 5x + 11 = A(x+3) + B(x+1)
So 5x + 11 = x(A+B) + 3A + B
The only thing that has x in right is (A+B)
So A+B = 5
And 3A + B = 11
So 2A=6
And A=3
B = 5 - 3 = 2
Answer:
Scale factor = ½
Step-by-step explanation:
The original image is the preimage = ∆ACB
The new image is the image = ∆DFE
The scale of factor of dilation = image/preimage = DF/AC
DF = 6 cm (given)
AC = 12 cm (given)
Plug in the values into the equation to find the scale factor of dilation:
Scale factor = 6/12
Scale factor = ½
Hello, this image may help. Does this look familiar to you?
I’d say A & C -
THERE !!✨,
3 and 12 are what they have in common
