Answer:

-5/4

Step-by-step explanation:

Slope is rise over run which means that the -5 will apply to your y values and the 4 will apply to your x values. This slope would have a point move down 5 units and to the right 4 units to get the location of the next point when going left to right. Because the slope contains a negative, the slope will be angled downward left to right. The negative only applies to the 5.

Hello, I hope you are having a splendid day. :)

The slope of this line is -5/4.

This equation is written in slope-intercept form, which looks like this:

y=mx+b

Where

m is the slope and b is the y-intercept.

So the slope is the number before x (in y=mx+b form).

The number before x is -5/4.

Therefore, -5/4 is the slope. Hope it helps. Ask me if you have any queries.

First, we will use the distributive property (order of operations) to simplify the equation:

(4)(5) + (4)(−8(4c−3)) = (12)(1) + (12)(−13c)+ (−8) =

20 + (−128c) + 96 = 12 + (−156c)+ (−8)

Now, we will combine like terms to simplify the equation:

(−128c) + (20 + 96) = (−156c) + (12+ (−8) =

−128c + 116 = −156c + 4

Now we will add 156 to both sides, using inverse operations.

−128c + 116 + 156c = −156c + 4 + 156c =

28c + 116 = 4

Now we will subtract 116 from both sides:

28c + 116 − 116 = 4 − 116 =

28c = −112

Lastly, we will divide both sides by 28:

28c/28 = c

-112/28 = -4

The equation now looks like:

c = -4

Therefore, your answer is -4.

Hi there! Hopefully this helps!

The tile in a bathroom or kitchen is one example of tessellation. It's where you place geometric shapes together to fill a space. In this case, we have squares placed together to fill the space of the wall or floor. There cannot be any gaps or overlaps.

Another example would be bricks as this is composed of rectangles placed together without any gaps or overlaps. There are many other examples as well usually done as floor or wall patterns of some kind. Some tessellations involve using more than one shape (eg: one pattern uses squares and equilateral triangles placed together).

Answer:

y = 4

Step-by-step explanation:

Move all terms containing y to the left, all other terms to the right. Add '-2y' to each side of the equation.

-5 + 3y + -2y = -1 + 2y + -2y

Combine like terms: 3y + -2y = 1y

-5 + 1y = -1 + 2y + -2y

Combine like terms: 2y + -2y = 0

-5 + 1y = -1 + 0

-5 + 1y = -1

Add '5' to each side of the equation.

-5 + 5 + 1y = -1 + 5

Combine like terms: -5 + 5 = 0

0 + 1y = -1 + 5

1y = -1 + 5

Combine like terms: -1 + 5 = 4

1y = 4

Divide each side by '1'.

y = 4

Simplifying

y = 4

Answer:

1 + 5x

Step-by-step explanation:

Like terms are terms with the same variable parts.

Let's look at each term:

3    it has no variable

5x    it has the variable x

-2    it has no variable

The terms 3 and -2 have no variables, so their variable parts are the same. They are like terms and can be combined. The term 5x has the variable part x. There is no other term with the same variable part as 5x, so 5x cannot be combined with anything.

3 + 5x - 2 =

= 3 - 2 + 5x

= 1 + 5x

Complete question :

At an ice carving competition, each carver starts with a block of ice with the dimensions shown. The block is wrapped in a special reflective material to keep it from melting before the competition starts. The side lengths of the block are 1.1, 0.8, 1.3. How much reflective material is needed to cover the block completely, without any overlaps?

Answer:

6.7 unit^2

Step-by-step explanation:

Taking the dimension of the ice block as :

1.1 by 0.8 by 1.3

The total reflective material which will used to cover the ice block must have the same surface area as the ice block.

Shape of ice block = rectangular prism.

Taking the surface area if a rectangular prism :

Using the relation :

2(lw * lh * wh)

Where l = Length = 1.1

Width w = 0.8

Height h = 1.3

Therefore,

2[(1.1*0.8) + (1.1*1.3) + (0.8*1.3)]

2[(0.88) + (1.43) + (1.04)]

2(3.35)

= 6.7 unit^2

Reflective material should be 6.7 unit^2

The total reflective material required is 6.7 square units

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.

Given that:-

The total reflective material which will be used to cover the ice block must have the same surface area as the ice block.

The shape of the ice block = is a rectangular prism.

Taking the surface area of a rectangular prism by using the relation :

SA = 2(  lw x   lh  x  wh  )

Where l = Length = 1.1

Width w = 0.8

Height h = 1.3

Therefore,

SA = 2 [(1.1 x 0.8) + (1.1  x 1.3) + (0.8  x  1.3)]

SA =  2  [  (0.88) + ( 1.43 ) + ( 1.04 )  ]

SA  =  2 ( 3.35 )

SA  = 6.7 square units

Therefore the Reflective material should be 6.7 square units

The mean is the average. To find it, add all numbers together and divide by how many numbers there are.

Median: 19

The median is the center number in the ordered line of numbers. I added a bolded variable (x), so you can see where it is. Because it's between two numbers, add those numbers and divide by 2.

Answer:

The area is 10 cm².

Step-by-step explanation:

The area of a triangle is 1/2 * bh where b = base and h = height. We know that b = 4 and h = 5 so the area is 1/2 * (4 * 5) = 1/2 * 20 = 10 cm².

I think your teacher meant to say Reflexive property instead of reflection. The reflexive property is the idea that any segment is the same length as itself. It seems like a trivial idea, but it's useful to be able to pull triangles apart like in this problem here.

Note: when naming a segment, the order of the endpoints listed doesn't matter. So that's why EU is the same as UE.

Answer:

8

Step-by-step explanation:

   (-11x/2 + 3) -2(-11x/4 -5/2)

=  -11x/2 + 3 -(2*-11x/4) -(2*-5/2)

=  -11x/2 + 3 -(-22x/4) -(-5)

=  -11x/2 + 3 +22x/4 + 5

=  -22x/4 + 22x/4 + 3 + 5

= 0 + 8

= 8

The value of the simplified expression is 8.

We have,

(-11/2 x + 3) - 2 (-11/4 x - 5/2)

To simplify the expression ((-11/2)x + 3) - 2((-11/4)x - 5/2), distribute the -2 to each term within the second set of parentheses and then combine like terms.

((-11/2)x + 3) - 2((-11/4)x - 5/2)

= (-11/2)x + 3 - 2 x (-11/4)x - 2 x (-5/2)

= (-11/2)x + 3 + (11/2)x + 5

= (-11/2)x + (11/2)x + 3 + 5

Combine like terms.

= 3 + 5

= 8

Answer:

1/2x +2

Step-by-step explanation:

Let's say there are 2 teams : A & B

A leads with x points, while B score 2 points less than half of B's score (x)

B = 1/2 of B score - 2

The difference of A - B = x - (1/2x - 2) = x - 1/2x + 2 = 1/2x + 2

The required difference in score is 1/2x + 2.

Given that,

In a basketball game, one team's score is two points less than half the other team's score, which is x. What is the difference in the score is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Let the score of the second team be x,
One team's score is two points less than half the other team's score
= 1/2x - 2
Difference of the score = x - (1/2x - 2)
                                       = x -1/2x +2

Answer:

(Choice C) C Replace one equation with a multiple of itself

Step-by-step explanation:

Since system A has the equations

-3x + 12y = 15 and 7x - 10y = -2 and,

system B has the equations

-x + 4y = 5 and 7x - 10 y = -2.

To get system B from system A, we notice that equation -x + 4y = 5 is a multiple of -3x + 12y = 15 ⇒ 3(-x + 4y = 5) = (-3x + 12y = 15).

So, (-x + 4y = 5) = (1/3) × (-3x + 12y = 15)

So, we replace the first equation in system B by 1/3 the first equation in system A to obtain the first equation in system B.

So, choice C is the answer.

We replace one equation with a multiple of itself.

Domain: [0, 12.75]

Range: [0, 590.9]

Step-by-step explanation:

Your function is missing variables.

I think you mean

h(t) = -4.922t^2 + 17.69t + 575

as the function.

We can find the time the object hits the ground. At that time, h(t) = 0, so we set the equation equal to zero and solve for t.

-4.922t^2 + 17.69t + 575 = 0

[tex] t = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] t = \dfrac{-17.69 \pm \sqrt{(-17.69)^2 - 4(-4.922)(575)}}{2(-4.922)} [/tex]

[tex] t = \dfrac{-17.69 \pm \sqrt{11633.54}}{-9.844} [/tex]

t = -9.16 s or t = 12.75 s

According to the parabola that is the path of the falling object, the object is at zero height at t = -9.16 s and t = 12.75 s. Since the object starts moving at time t = 0, the domain has to be limited to t = 0 till t = 12.75 s.

Domain: [0, 12.75]

The range is the height of the object. Maximum height occurs at the time that is the midpoint of the two times the parabola shows h(t) = 0.

tmax = (-9.16 + 12.75)/2 = 1.797

Now we use the time of maximum height to find the maximum height.

h(t) = -4.922t^2 + 17.69t + 575

h(tmax) = -4.922(1.797)^2 + 17.69(1.797) + 575

h(tmax) = 590.9

The maximum height is 590.9 m.

Range: [0, 590.9]
