Step-by-step explanation:
Given
f(x) = 8x - 9
Then
For a.
f(3y - 1 ) = 8(3y - 1 ) - 9
= 24y - 8 - 9
= 24y - 17
Now for b.
f(x) = - 23
or, 8x - 9 = - 23
8x = - 23 + 9
8x = - 14
x = - 14 / 8
x = - 7 / 4
Hope it will help :)
Answer:
answer 1 = true
answer 2 . Area of shaded part is 87m^2
<em><u>explanation in the pic above</u></em>
Y and the angle marked 60 degrees are internal alternate angles and are equal
so y = 60
Because AC is a diameter we can find the 180/3 = x
giving us the x= 60
Then that arc AB = 120
Answer:
a'b' and ab are the same length
