Hey there!

Let's solve your equation step-by-step.

[tex]\fbox{5y−6=2y(9)−32}[/tex]

Step 1: Simplify both sides of the equation.

[tex]\fbox{5y−6=2y(9)−32}[/tex]

[tex]\fbox{5y+−6=18y+−32}[/tex]

[tex]\fbox{5y−6=18y−32}[/tex]

Step 2: Subtract 18y from both sides.

[tex]\fbox{5y−6−18y=18y−32−18y}[/tex]

[tex]\fbox{−13y−6=−32}[/tex]

Step 3: Add 6 to both sides.

[tex]\fbox{−13y−6+6=−32+6}[/tex]

[tex]\fbox{−13y=−26}[/tex]

Step 4: Divide both sides by -13.

[tex]\fbox{−13y/−13 = −26/−13}[/tex]

[tex]\fbox{y=2}[/tex]

Answer:

The answer would be C im positive

Step-by-step explanation:

Using the definition of the absolute value function, it is found that:

It measures the distance of a point x to the origin, and is defined by:

[tex]|x| = -x, x < 0[/tex]

[tex]|x| = x, x \geq 0[/tex]

As for the expression used in this problem:

[tex]\frac{|x|}{x} = -\frac{x}{x} = -1, x < 0[/tex]

[tex]\frac{|x|}{x} = \frac{x}{x} = 1, x > 0[/tex]

Step-by-step explanation:

If x=1, then |x|/x= 1

If x=7, then |x|/x=1

If x=128, then |x|/x=1

If x>0, then |x|/x=1

If x=-8, then |x|/x=-1

Answer:

C

Step-by-step explanation:

f(x) = -2x-4

When, f(x) = 10,

-2x-4 = 10

-2x = 14

x = -7

Answer is C

Check the picture below.

[tex]\stackrel{\textit{\Large Areas}}{\stackrel{semi-circle}{\cfrac{1}{2}\pi (2)^2}~~ + ~~\stackrel{rectangle}{(4)(9)}~~ + ~~\stackrel{triangle}{\cfrac{1}{2}(5)(4)}}\implies 2\pi +36 + 10~~ \approx ~~ 52.28[/tex]

Step-by-step explanation:

that is a strange question. you will see in a moment why.

I suspect your teacher just wants to do the exercise to have a large volume and then see how often a small volume fits into that large volume.

we can do that quickly:

large volume = 10×2×312 = 6240 in³

small (cube) volume = 12×12×12 = 1728 in³

so, we could put 6240/1728 = 3.611111111... cubes into a volume as the prism has.

now why did I phrase this so strangely ?

because the prism not only has volume but also a shape.

it is a narrow but high container with the small dimensions being 10 in and 2 in.

the cubes have a side (or edge) length of 12 in. that is not compatible with the 10 in and 2 in cubes of the prism.

not a single one cube would fit into the prism.

so, the realistic answer is : 0 cubes.

if it does not matter that the cubes would stand out of the prism, we could simply stack a single file of cubes along the height of the prism :

312/12 = 26 cubes.

so, we could stack 26 cubes inside the height of the prism.

so, I conclude, this is either a trick question (and 0 is the true answer), or there is a mistake in the question.

possibly in the dimensions of either the prism or the cubes.

for example, let's assume the cubes have an actual side length of 2 in (and not 12 in).

then the small (cube) volume is : 2×2×2 = 8 in³

and they will fit into the prism also shape wise.

6240/8 = 780 cubes

so, we would need 780 cubes of that size to fill the prism.

or, as another example, the cubes have a side length of 1/2 in.

then the small (cube) volume = 1/2³ = 1/8 in³

6240/(1/8) = 6240 × 8 = 49,920 cubes

in that case we would need 49,920 cubes to fill the prism.

Answer:

The second option: The amount a customer pays increases $0.60 per  mile driven.

Step-by-step explanation:

As seen on the graph, we are given the points (20,12) and (35,21).

This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.

To find the rate of change we divide the distance driven by the cost to find the cost per mile:

20/12 = 0.6

35/21 = 0.6

The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per  mile driven.

Hope this helped!

Answer:

The amount a customer pays increases $0.60 per mile driven.

Step-by-step explanation:

$0.6/mi is the rate of change, y = mx + b, so m.is also called rate of change & b is the initial value of x, in the graph b = 0. making m the subject of the equation, then m(roc) = 0.6.

Answer:

90degrees

Step-by-step explanation:

I'm pretty sure, terribly sorry if I'm wrong

~Animaljamissofab ♥

nice green square lol

90°  is the measure of angle x°.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

Here, given that,

the figure is a square,

so, all its angle = 90 degrees

Now, the x = (180-90)=90

Hence, 90°  is the measure of angle x°.

f(x) = x^2 -5

Find f(3)

This means find x when it is 3 so just substitute 3 for x

f(3) = 3^2 -5

= 9 - 5

f(3) = 4

Answer:

f(3)=4

Step-by-step explanation:

f(x)=x^2-5

f(3)=3^2-5

f(3)=3*3-5

f(3)=9-5

f(3)=4

Answer:

x = - 1/2

Step-by-step explanation:

(3/2 - 6x) + 1 = 3 - 5x

-6x + 5/2 = 3 - 5x

5/2 = 3 - 5x + 6x

5/2 = 3 + x

5/2 - 3 = x

-1/2 = x

x = -1/2

Please mark me the brainliest!?!

[tex] \frac{3}{2} - 6x +1 = 3 - 5x \\ [/tex]

Plus sides 6x

[tex] \frac{3}{2} - 6x + 6x + 1 = 3 - 5x + 6x \\ [/tex]

[tex] \frac{3}{2} + 1 = 3 + x \\ [/tex]

Subtract sides -3

[tex] \frac{3}{2} + 1 - 3 = 3 - 3 + x \\ [/tex]

[tex] \frac{3}{2} - 2 = x \\ [/tex]

[tex] \frac{3}{2} - \frac{4}{2} = x \\ [/tex]

[tex]x = - \frac{1}{2} \\ [/tex]
