Answer:
y = x - 5
y = 2x + 5
Step-by-step explanation:
In linear equations, both variables x and y must have the exponent of 1 (i.e. they cannot have a small number at the top-right). And they cannot be in the exponents (i.e. cannot be the small number at the top-right).
A. 40°
∠Z=∠Y (base ∠ of isosΔ)
= 60°
∠X=180-60-60(∠ sum of Δ)
=40°
5.6
( 9 + 6 + 3 + 9 + 7 + 2 + 1 + 5 + 6 + 8 ) / 10
= 56 / 10
= 5.6
