B. and D. represent functions
Answer:
Part A:
x+y= 95
x = y+25
Part B: 35 minutes
Part C: No
Step-by-step explanation:
Eric spends a total of 95 minutes daily playing basketball and volleyball combined.
x+y= 95
Where:
x =minutes Eric plays basketball
y = minutes he allocates to volleyball
He dedicates 25 minutes more to basketball compared to volleyball.
x = y+25
Equations are:
x+y= 95
x = y+25
Substituting x=y+25 into the first equation yields:
(y+25) + y =95
Solving for y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C: No
If x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Inserting y=60 into the other equation:
x = y+25
35 = 60+25
35 ≠85
Response:
A. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}
Detailed explanation:
Having just taken the quiz, it's worth noting that you can interchange the coordinates to observe those of the inverse function. Instances of identical x values indicate that it fails the line test, thus disqualifying it as a function with an inverse.
Answer: La probabilidad que necesitamos es 0.16.
Step-by-step explanation:
Se nos proporciona que
La probabilidad de que el estudiante sea un senior = 0.22
La probabilidad de que el estudiante tenga una licencia de conducir = 0.30
La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36
Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.
Según la pregunta,

Por lo tanto, la probabilidad que necesitamos es 0.16.
Answer: 
Step-by-step solution:
Leon’s older brother’s height is
feet
feet
Because Leon is 1/3 foot shorter than his brother,
Leon’s height = 
Convert to like fractions by multiplying numerator and denominator: multiply 3 for the first fraction and 4 for the second.
So, Leon’s height = 
feet
Therefore, Leon’s height is
feet.
