Answer:
Hello! answer: 40
We know 1 angle is 50 degrees so that means the angle across will also be 50 degrees so that means 2 will be 40 degrees cause that is a complimentary angle and complimentary angles add up to 90 Hope this explains well!
Neither. Because an integer & a whole number are the same things & 5 1/2 is a fraction.
Answer:

Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
First rewrite the equation of the given line in the form of y=mx +c.
4x+5y=25
5y= -4x +25

The gradient of the given line is 
The product of the gradient of perpendicular lines is -1.

Thus, m= 

Substitute a coordinate to find c.
When x= -4, y= -6,

Hence, the equation of the line is

Answer:Yes.
Step-by-step explanation: Substitute either of the those values and you should get the other.
For instance, substituting x = 1 got you y = 5. If you had substituted x = 1 and got a different y-value, then the coordinates would have been incorrect.
Keep in mind that means is the same as asking for the average. all you need to do is add all the values and divide them by the number of values, which is 5
