Which equation can be used to verify that 534 – 68 = 466?
IgorC [24]

Answer:

466 + 68

Step-by-step explanation:

We can easily check a subtraction problem with an addition problem.

Calculate the sum of the subtracted and the difference. If the sum is equal to the minuend in the original subtraction problem, the answer is correct.

Minuend - Subtrahend = Difference

466 + 68 = 534

The statement '534 – 68 = 466' is correct.

Hope this helps.

State the vertex and axis of symmetry of the graph of y=ax2+c.
Neporo4naja [7]

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is y=ax^2 + bx +c

There is no bx in our given equation, so we put 0x

Given equation can be written as y=ax^2 + 0x +c

a=a , b=0

Now we use formula to find vertex

x=\frac{-b}{2a}

x=\frac{-0}{2a}=0

Now we plug in 0 for 'a' and find out y

y=a(0)^2 + 0x +c= c

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry
