Hey there!
-5x + 4
= -5(-3) + 4
= 15 + 4
= 19
Therefore, your answer is: 19
Good luck on your assignment and enjoy your day!

Answer:
15
Step-by-step explanation:
The product of distances from P to the two intersection points along the same secant (tangent) is the same for each. For this purpose, the tangent can be considered to intersect the circle twice at the same point. That is ...
PN·PM = PQ²
x(2x +7) = (x +6)²
2x² +7x = x² +12x +36
x² -5x -36 = 0
(x -9)(x +4) = 0 . . . . . . . true for x=9, x=-4
The relevant value of x is 9.
PQ = x +6 = 9 +6
PQ = 15
You already have all you need. Just put in it the slope-intercept form: y=mx+b where m is the slope and b is the y-intercept so
y=7x-4
<u>Answer</u>
1
<u>Explanation</u>
The general equation of a wave is ;
y = a sin(kX+Ф)
Where a represent the amplitude, 360/k represent the period of the wave and Ф represent the phase angle.
∴ In the equation y = 1 sin 2x,
Amplitude = 1
