Answer:
the correct answer is f(x)=(x-2)^2 + 1
Step-by-step explanation:
lets loof for f(2) :
f(2)=(2-2)^2 + 1
f(2)=(0)^2 + 1
f(2)= 1 ---> (2,1)
Step-by-step explanation:
This equations are quadratic equations, which is on standard form,
where a is the leading coefficient, b is the second coefficient, and c is the constant.
Both a and b are in quadratic equation so we need to find the constant separately.
Both sides are equal to zero so we can just subtract the terms not containing a or b in them to the opposite side.
For b,
Answer:
Step-by-step explanation:
It should be 10 months because if the tree grows 7 centimeters each month then in 10 months it'll be 70 and if she removes 6 inches off that'd be equivalent to 64 centimeters high
Answer:
30 miles in 90 minutes
Step-by-step explanation:
Just divide 90 and 3
The equation for the direct variation is y = 1.2x
In order to find this, we start with the base for any direct variation equation.
y = kx.
Now we use the ordered pairs to find the value of k to model the equation.
y = kx
24 = k(20)
1.2 = k
Now that we know this, we can model the equation as y = 1.2x and test for the other values --- each of which work in the newly written equation.
