-7, -2, 0, 5, 6 is the correct answer
Jonah should shade 6 parts of 10 equal parts to show 3/5.
Hope this helps! :)
Answer:
x=18
Step-by-step explanation:
y=3x-4
3x-4=y
3x-4=50
3x=50+4
3x=54
x=54÷3
x=18
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
Step-by-step explanation:
60° + 60° + x + x = 180°. (Sum of angles in a triangle = 180°)
Therefore 2x = 60° and x = 30°.
