Step-by-step explanation:
im working on the 2nd one rn ill get the answrr to u as fast as i can
ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y-intercept
You have to get y by itself:
5x + 8y = 16
-5x -5x
<u>8y = -5x + 15</u>
8 8
y = -5/8x + 15/8
OR
I you wants to simplify 15/8, it's this:
y = -5/8x +1.875
HI!!! Really really sorry if I'm incorrect...
<u>Answer: </u>
sec squared 55 – tan squared 55 = 1
<u>Explanation:</u>
Given, sec square 55 – tan squared 55
We know that,

And,

where Ө is the angle
Substituting the values

Solving,

According to Pythagoras theorem,

Putting this in the equation;
squared 55 - tan squared 55 =

Therefore, sec squared 55 – tan squared 55 = 1
