2² - y - 5 = 0 

Evaluate the power.

4 - y - 5 = 0

Calculate the sum or difference.

-1 - y = 0

Move constant to the right side and change its sign. 

-y = 1

Change the signs on both sides of the equation.

y = -1

Is y=3x+4 a function?
Oxana [17]

Answer:

Yes, it is a function

Step-by-step explanation:

Every possible input x value is paired with a unique output y value.

Another approach is to graph the function then conduct the VLT (vertical line test) at which point you will realize that any vertical line will intersect the graph at one point only meaning it is a function.

Hope this helps.

Points P and Q belong to segment AB . If AB = a, AP = 2PQ = 2QB, find the distance: between the midpoints of segments AP and QB
amid [387]

Answer:

\frac{a}{8}

Step-by-step explanation:

AB = a

AP = 2PQ = 2QB

AB = AP + PQ + QB

     = AP + \frac{AP}{2} + \frac{AP}{2}

AB = 2AP

AP = \frac{a}{2} -----(1)

And we know QB = \frac{AP}{2}

QB= AP/2 = \frac{a}{4} ---------(2)

Now midpoint of AP = \frac{a}{2} × \frac{1}{2} = \frac{a}{4}

and midpoint of QB = \frac{a}{4} × \frac{1}{2} = \frac{a}{8}

distance between these midpoints = \frac{a}{4} - \frac{a}{8}

= \frac{a}{8}
