Is the same as seven less than a number(x) : x-7
now in your case what would be the answer ?
The purifier filters 1/3 water
Since the intersection is - by definition - common to both sets, we can work out the number of people that use only the fitness suite or the swimming pool.
We know that 57 people use the fitness suite, but 36 of those are already counted in the intersection. So, 57-36=21 people use only the fitness suite.
The same goes for the swimming pool: 49-36=13 people use only the swimming pool.
So, we have:
- 21 people using fitness suite only
- 13 people using swimmng pool only
- 36 people using both
This sums to 21+13+36=70 people. We deduce that 30 people don't use any of the features.
Answer:
The answer is A) y =3x + 3
Step-by-step explanation:
You substitute the gradient and y intercept into the equation of y = mx +b
Answer:
Step-by-step explanation
subtract 8 from both sides
8-2x-8=-4x+4-8
simplify
-2x=-4x-4
add 4x to both sides
-2x+4x=-4x-4+4x
Simplify
2x=-4
divide both sides by 2
2x/2=4/2
simplify
x=-2
