The linear equation is y = 4 + 0.5x
<h3>How to determine the equation?</h3>The points are given as: (-2,3) and (4,6)
The equation is then calculated using:
Substitute the known values
Evaluate
y = 0.5 *(x+2) + 3
Expand
y = 0.5x + 1 + 3
Evaluate the sum
y = 0.5x + 4
Rewrite as:
y = 4 + 0.5x
Hence, the equation is y = 4 + 0.5x

Answer:
The correct option is (C).
Step-by-step explanation:
The exponential function representing decay is as follows:
Here,
<em>y</em> = final value
<em>y</em>₀ = initial value
<em>k</em> = growth rate
<em>t</em> = time passed
The graph represents exponential decay is:
"On a coordinate plane, a graph approaches y = 0 in quadrant 1 and curves up into quadrant 2."
Thus, the correct option is (C).
Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
=
, substitute values
=
( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b = ≈ 9.5 ( to the nearest tenth )
Also
=
=
( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c = ≈ 14.7 ( to the nearest tenth )
