Answer:

b (-3/5)

Step-by-step explanation:

First, distribute the -2 on the left side

-2x-2=3x+1

now, add 2 to both sides

-2x=3x+3

subtract 3x from both sides

-5x=3

divide both sides by -5

x=-3/5

F(x) = −(x2 + x − 72) what is the axis of symmetry and write it in standard form
Strike441 [17]
F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry

A rectangle as the width of 9 units and length of 40 units. What is the length of the diagonal?
Kitty [74]

Answer:

the Diagonal is 41 units

Step-by-step explanation:

Since the sides of a rectangle, to be a rectangle, meet at 90° we use Pythagorean Theorem a² + b² = c²  

Width and Length are the legs and the diagonal is the hypotenuse

9² + 40² = c²

81  + 1600 =  c²

1681 = c²

√1681 = √c²

41 = c
