Answer:
(A.) x = y - 4
Step-by-step explanation:
All you need to do is subtract the 4 from both sides, giving you the final equation as x = y - 4.
Answer:
The answer to your question is the last option
Step-by-step explanation:
Process
1.- To calculate the rate of change, calculate slope
Formula
m = (y2 - y1) / (x2 - x1)
x1 = 1 y1 = 1200
x2 = 2 y2 = 2400
2.- Substitution
m = (2400 - 1200) / (2 - 1)
3.- Simplification
m = 1200 / 1
4.- Result
m = 1200 meters / minute
The period of the y=1/2 sin (2x)-3 is 2.
We have given that,
y=1/2 sin (2x)-3
We have to determine the period
<h3>
What is the period?</h3>
A period is the part of the menstrual cycle when a woman bleeds from her vagina for a few days.
Normally the period of sin(2x) is 2x, but the pi inside the sin(2x) is a horizontal compression by a factor of 1/pi.
So 2pi·1/pi = 2
The 1/2 and -3 do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.

Answer:
The best estimate for the value of the given expression is -2 1/2. Correct: Second alternative
Explanation:
<u>Estimate and Number Rounding</u>
There are situations where numbers must be estimated according to certain rules. If we have a number and we need a good approximate to it, we can use rounding to the required number of decimals.
The question requires to find the best estimate for the operation:
We calculate the decimal value of the expression:
The first alternative is incorrect. It's a good approximation because it's close to the number, but the next alternative is the closest of all choices.
The second alternative Is correct. The value of -2 1/2 is -2.5. The number -2.64 is closer to -2.5 than to -3 which is the alternative A.
The third alternative Is incorrect. 7 is a positive number and it's not even close to -2.64
The last alternative Is incorrect. 7 1/2 = 7.5 is a positive number and it's not even close to -2.64
Answer:
21
Step-by-step explanation:
To get the common denominator of two numbers that are not multiples of each other, you multiply the two denominator
So, 7×3=21
