Answer:

Second graph only.

Step-by-step explanation:

The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.

If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)

If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.

Draw the graph of the equation<br><br> x+y=5
Advocard [28]

well first you have to get x and y on separate sides so subtract x by both sides to put x on the right side.

now you have y = 5 - x

to graph that let's throw in some numbers for x and y and make a function table

x, y

1, 4

2, 3

3, 2

4, 1

5, 0

6, -1

and so forth

as you can see as x increases in value, y decreases in value

all you have to do now is plot those points on a graph

A square has an area of 64 ft? What is the length of each side?
exis [7]

Answer:

8 ft.

Step-by-step explanation:

The formula for area of a square is:

A=s^2

We are given the area of 64 square feet.

64=s^2\\\\\sqrt{64}=\sqrt{s^2}\\\\  \boxed{8=s}

Each side should be 8 ft.
