Answer:
Range of Function : { - 9, - 5, - 1, 4 }
Step-by-step explanation:
We know that y = 2x - 5 provided the domain ( x - values ) { - 2, 0, 2, 4 }. Let us substitute each element in this set of domain as x in the equation "y = 2x - 5" as to solve for the y - values, otherwise known as the range of the function.
{ - 2, 0, 2, 4 }
y = 2( - 2 ) - 5 = - 9,
y = 2( 0 ) - 5 = - 5,
y = 2( 2 ) - 5 = - 1,
y = 2( 4 ) - 5 = 4
We have the set of y - values as { - 9, - 5, - 1, 4 }. This is the range of our function.
The planes will pass each other in 1.14 hours.
Why?
To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.
The speed will be:
Now, calculating the time, we have:
Hence, the planes will pass each other in 1.14 hours.
Have a nice day!
The value of x for both angles to be vertically opposite is 27
<h3>Vertical angles</h3>
The measure of vertical angles are equal and they are angles that meet at the point of intersection of two lines.
In order to determine the value of x, we will equate both angles to have;
2x = 54
Divide both sides by 2
2x/2 = 54/2
x = 27
Hence the value of x for both angles to be vertically opposite is 27
