Answer:
The slope <em>m</em> is 1.9 and the y-intercept <em>b</em> is 2.5.
Step-by-step explanation:
This is in slope-intercept form, y=<em>m</em>x+<em>b</em>, where <em>m</em> is slope and <em>b</em> is the y-intercept.
y = 1.9x + 2.5 means that <em>m </em>is 1.9 and <em>b</em> is 2.5.
<h3>Given:</h3>
<h3>To find:</h3>
How much is $100 in ZA rands.
<h3>Solution:</h3>
Let the unknown be "x"

We'll have to do cross multiplication.
So we'll have to multiply 100 and 17.

Answer: A = 4 P = π PS = -π/2
<u>Step-by-step explanation:</u>
y = A sin(Bx - C) + D where
- A is the amplitude
- Period = 2π/B
- Phase Shift = C/B
- D is the vertical shift
Given: y = -4 sin(2x + π) - 3
- A (amplitude) = 4 <em>the negative sign is a reflection, not amplitude</em>
- B = 2
- C = -π
- D = -3
Amplitude = 4
