Step-by-step explanation:It says:
There are 3 strawberry yoghurts, 2 peach yoghurts and 4 cherry yoghurts in a fridge.
Kate takes a yoghurt at random from the fridge.
She eats the yoghurt.
She then takes a second yoghurt at random from the fridge.
Work out the probability that both yoghurts were the same flavour.
First you plug in for x,
2(y-3)+y=12
Then you solve for y
2y-5+y=12
-10y+y=12
-9y=12
-9y/9=12/-9
y=-1.333333333333333333333333333333333333333333333333333333333
It is close to 200 because 150 or above would be rounded to 200. Below 150 would be 100
For the pair of functions, find the indicated sum, difference, product, or quotient.
f(x) = 6 - 7x, g(x) = -3x + 7
Find (f + g)(x).
