Answer: The winning ticket is 2(x-6)=-35 is equivalent to 2x=-23.



Step-by-step explanation:

Let's check all the options

4(x-5)=35 is not equivalent to 4x=40

\text{since }4(x-5)=35\\\Rightarrow4x-20=35\\\Rightarrow4x=35+20\\\Rightarrow4x=55

8(x-7)=35 is not equivalent to 8x=28


\text{since }8(x-7)=35\\\Rightarrow8x-56=35\\\Rightarrow8x=35+56\\\Rightarrow8x=91

2(x-6)=-35 is equivalent to 2x=-23


\text{since }2(x-6)=-35\\\Rightarrow2x-12=-35\\\Rightarrow2x=-35+12\\\Rightarrow2x=-23

9(x-6)=-35 is not equivalent to 9x=-29

\text{since }9(x-5)=-35\\\Rightarrow9x--40=-35\\\Rightarrow9x=-35+40\\\Rightarrow9x=5

Thus, the winning ticket is 2(x-6)=-35 is equivalent to 2x=-23.

The functions f(x) = (x + 1)2 − 2 and g(x) = −(x − 2)2 + 1 have been rewritten using the completing-the-square method. Apply you
galina1969 [7]

Answer:

f(x)=(x+1)^2-2 is the minimum and g(x)=-(x-2)^2+1 is the maximum

Step-by-step explanation:

Looking at the graph, (you should be able to graph this) the parabola for f(x)=(x+1)^2-2 is pointing downwards and stops at the vertex. This vertex is negative which is the lowest point possible which makes it the minimum. The parabola for -(x-2)^2+1 is pointing upwards and stops at the vertex which is the highest point possible which makes it the maximum.

Help me please<br>help ​
AlekseyPX

Answer:

153 cubic feet

Step-by-step explanation:

V = kha .........where h is height and a area and V is volume

92 = k * 12 * 23

k = 92/(12*23) =1/3

if k, constant is 1/3

volume =1/3 * 17 * 27

=153 cubic feet

If the measure of arc CB is 8/3 units, what is the measure of CAB?
Oksanka [162]

Question:

If the measure of arc CB is \frac{8}{3} \pi units, what is the measure of ∠CAB?

Answer:

120°

Step-by-step explanation:

The figure has been attached to this response.

The figure shows a circle centered at A and has a radius of 4 units.

Also, the length of the arc CB (as given in the question) is  \frac{8}{3} \pi units.

The length <em>L </em>of an arc is given by;

L = \frac{\beta }{360} * 2\pi  * r         -----------------(i)

Where;

β = angle subtended by the arc at the center of the circle and measured in degrees

r = radius of the circle

From the question;

β = ∠CAB

r = 4 units

L =  \frac{8}{3} \pi

<em>Substitute these values into equation (i) as follows;</em>

\frac{8}{3} \pi = \frac{\beta }{360} * 2\pi  * 4

=>  \frac{8}{3} \pi = \frac{\beta }{360} * 8\pi

<em>Cancel 8</em>\pi<em> on both sides</em>    

\frac{1}{3} = \frac{\beta }{360}

<em>Cross multiply</em>

3 x β = 360 x 1

3β = 360

<em>Divide both sides by 3</em>

<em />\frac{3\beta }{3} = \frac{360}{3}<em />

β = 120°

Therefore, the measure of ∠CAB is 120°
