Which pair of expressions is equivalent?​

Answer: 50

Step-by-step explanation:

Answer:

[tex]y=-\frac{1}{4} x-6[/tex]

Step-by-step explanation:

The slope-intercept form is [tex]y=mx+c[/tex], where m is the slope of the line and c is where the line crosses the [tex]y[/tex]-axis.

To calculate [tex]m[/tex] we can use the formula [tex]m = \frac{dy}{dx}[/tex] where [tex]dy[/tex] is the difference in [tex]y[/tex] between two points and [tex]dx[/tex] is the difference between [tex]x[/tex].

Information we can get from the graph given: [tex]c=-6[/tex]. Since [tex]c[/tex] is the point at which the line crosses the [tex]y[/tex]-axis.

To find [tex]m[/tex] let's get two points from the graph.

Point 1: [tex](4,-7)[/tex]

Point 2: [tex](8,-8)[/tex]

Now use the equation [tex]m = \frac{dy}{dx}[/tex].

[tex]m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}[/tex].

Now we have [tex]m[/tex] and [tex]c[/tex], let's put them back into the general equation.

[tex]y=-\frac{1}{4} x-6[/tex]

Answer: C. Pyramid

Step-by-step explanation:

A cylinder is kind of like a paper towel roll.

A Rectangular prism is more like a cube.

A cone has a round part on the bottom.

And a Pyramid is this ...

Answer:

∠ ABD = 42°

Step-by-step explanation:

∠ ODC = 90° ( angle between tangent and radius )

∠ ADC = 90° - 48° = 42°

The angle between a tangent and a chord is equal to the angle in the alternate segment, that is

∠ ABD = ∠ ADC = 42°

Answer:

I don't know what prism. once you see this put it in the description of this

Step-by-step explanation:

Answer:

We add up all the numbers:

84 + 72 + 96 + 97 + 75 + 83 + 81 = 588

Since there are 7 numbers we divide by 7

588 divided by 7 = 84 is your mean

Step-by-step explanation:

How to find mean:

Add up the numbers, divide by the many numbers there are and thats how you find your mean.

Answer:

x=-2

Step-by-step explanation:

4+8x=-12

-4       -4

8x = -16

/8      /8

x   =   -2

Answer:

X=(-2)

Step-by-step explanation:

8(-2)=(-16)

so -16+4=(-12)

Answer:

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

⇒ Measurement of the arc VU= 80°.

Answer:

80 is the correct answer

Awnser :

Ten

Explanation :

In a relaxed practice setting with no pressure, the average player should be able to make at least ten in a row. But free throws typically come in pressure situations, so managing the pressure is as important as practicing form.

Answer:

4.87805%

Step-by-step explanation:

yuh yw

Answer:

= 4.87805% difference

Solution:

Calculate percentage difference

between V1 = 239900 and V2 = 251895

|V1−V2|[(V1+V2)2]×100=?

=|239900−251895|[(239900+251895)2]×100

=|−11995|[4917952]×100

=11995245897.5×100

=0.0487805×100

=4.87805%difference

Answer:

Answer:

  90

Step-by-step explanation:

The number that goes in the blank is x, where ...

  0.30x = 27

Dividing by 0.30, we find ...

  x = 27/0.30 = 90

Then ...

  30% of 90 = 27

Answer:

A, E

Step-by-step explanation:

The mean of the pizza truck:

(400 + 800 + 1000 + 1000)/4 = 800

The mean of the burger truck:

(800 + 700 + 900 + 800)/4 = 800

A is correct, which voids answer C

The median of the pizza truck:

400, 800, 1000, 1000

              \     /

               900

The median of the burger truck

700, 800, 800, 900

            800

900>800 so E is correct, voiding all other answers

Answer:

first answer is correct answer

Answer:

B; 1

Step-by-step explanation:

Firstly, we need to find the inverse of the given function

Let us have f(x) as y

To find the inverse, we set out to make x the formula subject

Thus;

y = √(3x + 6)

square both sides

y^2 = 3x + 6

3x = y^2 - 6

x = (y^2 - 6)/3

To write the inverse, replace y by x

So we have the inverse of the function as ;

(x^2 - 6)/3

So what we have to do here is to substitute 3 for x in the inverse

We have this as;

(3^2 -6)/3

(9-6)/3

= 3/3 = 1

Answer:

1 ( option B )

Step-by-step explanation:

The given equation is ,

[tex]\implies f(x) =\sqrt{ 3x + 6 }[/tex]

Now substituting y = f(x) , we have ,

[tex]\implies y=\sqrt{ 3x + 6 }[/tex]

For finding the inverse , Interchange x and y , we have ,

[tex]\implies x =\sqrt{ 3y + 6 }[/tex]

Now solve for y , we have ,

[tex]\implies x ^2=3y + 6 \\\\\implies 3y = x^2-6 \\\\\implies y =\dfrac{x^2-6}{3} [/tex]

Now replace y with f-¹(x) , we have ,

[tex]\implies f^{-1}(x) =\dfrac{x^2-6}{3} [/tex]

Now put x = 3 , we have ,

[tex]\implies f^{-1}(3) =\dfrac{3^2-6}{3}\\\\\implies f^{-1}(3) = \dfrac{9-6}{3}\\\\\implies \underline{\underline{ f^{-1}(3) = 1 }} [/tex]
