Square roots and squares cancel eachother. therefore the problem is simply:
2.35 + -4.27= -1.92
Answer:
Betty = $600
Step-by-step explanation:
3/4 of Alice's salary is the same as 1/2 of Betty's salary
(3/4)a = (1/2)b
multiply both sides by 2
(3/2)a = b
Alice earns $200 less than Betty
b - a = 200
Substitute for b
(3/2)a - a = 200
(1/2)a = 200
multiply both sides by 2
a = 400
b = (3/2)400
b = 600
Answer:

Step-by-step explanation:
Since we are finding a parallel line, the slopes will be the same, so the second equation will also have a slope of -5.
Then, to find the y-intercept, we can use the point given and plug in.




So the equation comes out to be 
We can check by plugging in the given point again.



Answer:
2√2
Step-by-step explanation:
Given
g(x) = ✓(x - 4)
h(x) = 2x - 8
Now
g(h(10))
= g ( 2 * 10 - 8)
= g(20-8)
= g(12)
=✓(12 - 4)
= ✓8
=2√2
Hope it will help ✓
