This is a function where:
x - time in minutes;
y = f ( x ) - altitude of a plane in feet.
Max altitude = 35,000 feet
0.5 h + 2 h + 15 min = 30 min + 120 min + 15 min = 165 min
Domain:
x ∈ [ 0; 165 ]
Range:
y ∈ [ 0; 35,000 ]
Answer:
12
Step-by-step explanation:
aaaaaaaaaaaaaaaaaaaaa
Y= 3x - 10
<span>3x + 2y = 16
3x+2(3x-10)=16
3x+6x-20=16
9x-20=16
9x=36
x=4
y=3x-10
y=3(4)-10
y=12-10
y=2</span>
its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2
it will now look like this: 6y - 2 + 7y = 12
then your going to want to add 2 to both sides of the equation.
it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14
simplify: 6y + 7y = 14
add the like terms: 13y = 14
