For slope m and point (x₁, y₁), the point-slope equation of the line can be written as
  y -y₁ = m(x -x₁)

You have m = -4 and (x₁, y₁) = (4, -9), so the equation of your line is
  D. y+9 = -4(x-4)

Multiply the equation 2x+7y=-1 by -2

add to othe equaiton
4x-3y=-19
<u>-4x-14y=2 +</u>
0x-17y=-17

-17y=-17
divide both sides by -17
y=1

sub back
2x+7y=-1
2x+7(1)=-1
2x+7=-1
minus 7 from both sides
2x=-8
divide both sides by 2
x=-4

x=-4
y=1

Sergeu [11.5K]

Answer:

Notice on the graph y = sin x, the graph passes through the origin (0,0). Then the graph crosses the x-axis at (p,0). When we make c positive, we move the graph to the left c units

What are the points of inflection of k(x)=sinx-(1/4)sin2x
zalisa [80]

Answer:

Option d is correct.

Step-by-step explanation:

The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.

Now, the given function is

k(x) = \sin x - \frac{1}{4}\sin 2x

Differentiating with respect to x on both sides we get,

k'(x) = \cos x - \frac{1}{2} \cos 2x

Again, differentiating with respect to x on both sides we get,

k''(x) = - \sin x + \sin 2x = - \sin x + 2 \sin x \cos x

So, the condition for point of inflection at point c is

k''(c) = 0 = - sin c + 2 sin c cos c

⇒ sin c(2cos c - 1) = 0

⇒ sin c =  0 or \cos c = \frac{1}{2}

⇒ c = 0 or c = \pm \frac{\pi}{3}

Therefore, option d is correct. (Answer)

Scilla [17]
#10) The original graph has x intercept 0 and y intercept 0.  The new graph has x intercept 3 and y intercept -3

So x went up 3 and y went down 3.  The answer is H.

#11) Plug in x = 0 and solve.  The answer is 48, C.

#12)  Use a graphing calculator or online calculator.  I got r = 0.778

#13)  The only one that is shaded correctly is H.
