Answer:
12
Step-by-step explanation:
If you use the pathagrem therom a^2+b^2=c^2 and fill it in it would be 9^2+b=15^2.
Then just do basic math to simplify the equation
9*9=81
15*15=225
81+b= 225
b= 225-81
b= 144
finally square root 144 and thats how you get 12

Answer:
y = 4 is the correct solution.
Step-by-step explanation:
If x = 8, then we can plug this into the equation 5y – 2x = 4 to solve for y:
5y – 2(8) = 4
5y – 16 = 4
5y = 20
y = 4
Therefore, the solution to the system of equations 5y – 2x = 4 and x = 8 is y = 4.
We can check our answer by substituting y = 4 into the original equation:
5(4) – 2x = 4
20 – 2x = 4
-2x = -16
x = 8
Since x = 8 is a solution to the original equation, we can confirm that y = 4 is the correct solution.
b. 80 minutes
c. 200 minutes
d. 240 minutes HELP?!
Answer:
If they work together, they take 48 minutes to line the football field.
Step-by-step explanation:
Given: Reggie can line a football field in 120 minutes. Rosalinda can line a football field in 80 minutes.
To find : If they work together, how many minutes does it take them to line a football field?
Solution :
If they work together,
Let the number of minutes(x) they take to line the foot ball field.
According to question,
Cross multiply,
Therefore, If they work together, they take 48 minutes to line the football field.
Answer: If they work together, they can line a football field in 48 minutes.
Step-by-step explanation: Given that Reggie can line a football field in 120 minutes and Rosalinda can line a football field in 80 minutes.
We are to find the number of minutes does it take them to line a football field if they work together.
We have
Time taken by Reggie to line a football field = 120 minutes.
So, in 1 minute, Reggie can line part of the field.
Time taken by Rosalinda to line a football field = 80 minutes.
So, in 1 minute, Rosalinda can line part of the field.
Therefore, if they work together, the portion of the football field that they can lie in 1 minute is given by
Thus, if they work together, they can line a football field in 48 minutes.
f(x) = 4x − 3
f(x) = 4x + 3
f(x) = 4(x + 3)
Answer:
f(x) = 4^x -3
Step-by-step explanation:
All of the listed functions are linear functions with a constant slope of 4. None of them goes through the point (0, -2).
__
So, we assume that there is a missing exponentiation operator, and that these are supposed to be exponential functions. If the horizontal asymptote is -3, then there is only one answer choice that makes any sense:
f(x) = 4^x -3
_____
The minimum value of 4^z for any z will be near zero. In order to make it be near -3, 3 must be subtracted from the exponential term.
