Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table
m =
=
=
= 5
The line crosses the y- intercept at (0, - 2 ) , then
y = 5x - 2 → C
The relationship that sin x° and cos y° share is that; cos x = sin y and sin x = cos y = 12/13
<h3>How to work with Pythagoras Theorem?</h3>
From the definitions of trigonometric ratios, we know that;
sin x = opposite leg/hypotenuse
cos y = adjacent leg/hypotenuse
From the Pythagorean theorem, we can find the hypotenuse as;
6² + 8² = hypotenuse²
The cosine is the sine of the complementary angle. Since x and y are complementary angles as they sum up to 90°, we have cos x = sin y and sin x = cos y = 12/13

A * b = 21 and b * c = 39. then b is the common factor of the two numbers.
We need to factor these two numbers to know their equivalent values.
21 factors are 1, 3, 7, 21
39 factors are 1, 3, 13, 39
if b = 3, then a = 7 and c = 13.
To check:
a * b = 21 where 7 * 3 = 21 and b * c = 39 where 3 * 13 = 39
We can then conclude the following:
3 is lesser than 7 which is lesser than 13. where b < a < c
OR 13 is greater than 7 which is greater than 3. where c > a > b
not sure if these answers are included in your choices but i hope this helps.
Step 1 : calculate the difference between the 2 numbers: 25 -20 = 5
step 2: divide the difference by the original amount: 5 /20 = 0.25
step 3: multiply the decimal by 100 to get the percentage: 0.25 * 100 = 25% increase
