Answer: 10:7
Step-by-step explanation:
40:28=10*7
Answer:
30 is the wrong one because it is not a factor of 100
30 60 90 120
20 40 60 80 100
Step-by-step explanation:
In order to solve the given expression follow these steps:
1. Take the square roots on both sides in order to get rid of the power on the left side:
√(x-5)² = ±√3
x - 5 = ±√3
2. add 5 on both sides:
x-5 + 5 = 5 ±√3
x = 5 ±√3
Then, the solution is x = 5 ±√3
Answer:
b) y = f(x - 7) - 3
Step-by-step explanation:
it adds if its goes to the right and subtracts if it goes to the left
And when it goes down then it will also decrease in number.
that is why b) y = f(x - 7) - 3 is the correct answer to put
