Answer:
Hence correct chcie is C.
Step-by-step explanation:
Given function is
Now it says that function is shifted 4 units to the left and 4 units up.
We need to find about which of the given choice is correct for the given transformation.
When f(x) is shifted "h" units left then we write f(x+h)
So will change to
When f(x) is shifted "h" units up then we write f(x)+h
So will change to
Answer:
x=-1 and y=-5
Step-by-step explanation:
ሰላም!
Given expressions let them given as two equations
Thus, substitute y=2+7x into equation (2)
simplify it
subtract 12 from both sides
divide both sides by 40
Therefore, as we get the value of x=-1 substitute it to equation (1) and solve for variable y
To be more sure make a cross check on both of the two expressions
Thus,
1) y=2+7x .... substitute y=-5 and x=-1 and check if it is equal
-5=2+7(-1)
-5=2-5
-5=-5
2)-2x+6y=-28... substitute and check
-2(-1)+6(-5)=-28
2-30=-28... (-a)(-b)=ab
-28=-28
Hope it helps!
