Answer: y = 4x - 3
Explanation: 5 = 4x2 - 3
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
-6.4 – 4(-2.8)
-6.4 – - 11.2 = 4.8
Your answer is B: 4.8
Answer:
= 5
Step-by-step explanation:
Substitute the given values into the formula
16 = 
× 4(3 + )
16 = 2(3 + ) ( divide both sides by 2 )
8 = 3 + ( subtract 3 from both sides )
5 =
