.75 because .75 is .25 from 1.0 and .25 from .5
It's C.
multiply by 3
x = 4, y = 4x3 = 12
x = 5, y = 5x3 =15
x = 6, y = 6x3 =18

Answer:
x = 6
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² + (x + 2)² = 10² ← expand parenthesis on left side and simplify
x² + x² + 4x + 4 = 100 ( subtract 100 from both sides )
2x² + 4x - 96 = 0 ( divide through by 2 )
x² + 2x - 48 = 0
(x + 8)(x - 6) = 0 ← in factored form
equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 6 = 0 ⇒ x = 6
however, x > 0 , then x = 6
Answer:
Step-by-step explanation:
since the line crosses the y axis at -4 we know that b in the slope intercept form is -4 . now we just need the slope.. and slope is rise over run or y/x... soooo .....
looking at the graph I see that the point (-1,4) and (0,-4) look like they are points on the graph..
soooo....
the rise is -8 when the run is 1 or -8/1 or just -8
use the slope intercept form y = mx + b
y= -8x + (-4)
y = -8x -4 :)
