-Graphing Linear equalities with slope and y-intercept-

Answer:

This means that line l and line m are perpendicular.

Step-by-step explanation:

Answer:

GCF is Greatest common factor and LCF Is least common factor

Answer:

slope = 1

y-intercept = -3

equation:  y = x - 3

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

choose any 2 consecutive x. y pairs and plug the numbers into the equation.  I pick (0, -3) and (1, -2)

slope = (-2 - -3 / (1 - 0) = 1/1 = 1

y-intercept = -3     this is where the line crosses the y axis at point (0, -3)

Equation:  y = mx + b = (1)x + (-3) = x - 3

y = x - 3

To draw the graph, it's easy (sorry, Brainly doesn't provide drawing tools):

put the first point at (0, -3) then go up 1, over 1, up 1, over 1, etc. because the line has a slope of 1/1.

the line should slant up because it has a positive slope

Answer:

the correct answer is D

Step-by-step explanation:

Answer:

Radius = 2.5559cm

To the nearest tenth = 3cm

Step-by-step explanation:

Volume of bottle = 160cm³

Height of bottle = 7.8cm

π = 3.14

Radius of bottle = r

Using the formula,

160 = (3.14)(r)²(7.8)

160= 24.492r²

Dividing both sides by 24.492,

160/24.492 = r²

r² = 6.5327, which is approximately 6.533

Making r the subject,

r = √6.533

r = 2.5559, which is approximately 2.556

Round to the nearest tenth = 3

Therefore, the radius of the cylindrical bottle is 3cm.

Answer:  E)1/4y=2x

Step-by-step explanation:

The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. If the constant of proportionality is 1/4, it means that the dependent variable is one-fourth the value of the independent variable.

So, we need to determine which equations have a constant of proportionality of 1/4:

A) y = 4x

The constant of proportionality in this equation is 4, not 1/4.

B) y = 0.25x

The constant of proportionality in this equation is 1/4.

C) 4y = x

The constant of proportionality in this equation is 1/4, since we can rewrite it as y = 1/4x.

D) 32y = 8x

We can simplify this equation by dividing both sides by 8:

4y = x

The constant of proportionality in this equation is 1/4.

E) 1/4y = 2x

We can rewrite this equation as:

y = 8x

The constant of proportionality in this equation is 8, not 1/4.

Therefore, the equations for which the constant of proportionality is 1/4 are B), C), and D).

Answer:

  B, C, D

Step-by-step explanation:

You want to identify the equations that have a constant of proportionality of 1/4.

A proportional relationship can be written in the form ...

  y = kx

where k is the constant of proportionality.

You want to identify those relations that are equivalent to this with k=1/4.

A) y = 4x . . . . . k = 4 ≠ 1/4

B) y = 0.25x . . . . . k = 0.25 = 1/4

C) 4y = x   ⇒   y = 1/4x . . . . . k = 1/4

D) 32y = 8x   ⇒   y = 8/32x = 1/4x . . . . . k = 1/4

E) 1/4y = 2x   ⇒   y = 2/(1/4)x = 8x . . . . . k ≠ 1/4

The relations with a constant of proportionality of 1/4 are B, C , D.

Answer:

54 m²

Step-by-step explanation:

a cube's sides are all the same, and it has 6 sides, so simply find the area of one side and multiply that by 6.

3×3 = 9

9×6 = 54

Answer :

a - binominal = an algebraic expression of the sum or the difference of two terms. So I put it in the perimter 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60. just put that ig ??

Question : Is this RSM? Because if I knew the grade ,  advanced/normal/honors I would be able to help u more

Solve step by step : x=12 because it said the height is 12.

Inside, x-6, so therefor it would really be, 12-6. Which we know would be 6.

Perimeter : 60

now we know the inside is 6. The outside height is 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60.

Answer: 126 in ^2

Step-by-step explanation:

The surface area of a rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we get:

Surface Area = 2(3)(5) + 2(3)(6) + 2(5)(6)

Surface Area = 30 + 36 + 60

Surface Area = 126 square inches

Therefore, the surface area of the rectangular prism is 126 in^2.

Answer:

1064

Step-by-step explanation:

To calculate the number of students the high school is anticipating next year, we need to find 12% of the current enrollment and add it to the current enrollment:

12% of 950 = 0.12 * 950 = 114

So the high school is anticipating an additional 114 students next year.

To find the total anticipated enrollment, we add the additional 114 students to the current enrollment of 950:

Total anticipated enrollment = 950 + 114 = 1064

Therefore, the high school is anticipating 1064 students next year.

Answer:

graph 1 is correct.

Step-by-step explanation:

According to the information, the distribution of the data is multimodal distribution.

To find the type of distribution of the graph we must analyze the graph and identify the values and the frequency of each of the values. Based on this information, we can establish that the type of distribution of this graph is multimodal distribution.

According to the data in the graph, we can infer that it is a multimodal distribution because it has low and high points in different variables and does not have an established pattern.

6. 300 grams of carbohydrates are recommended per day

Answer:

See below.

Step-by-step explanation:

For this problem, we are asked to find equivalent expressions.

We should use the Distributive Property.

The Distributive Property is a property that allows us to multiply the number outside of the parentheses into the numbers inside the parentheses. Think of the Distributive Property in the form of x (y + z); We multiply x with y and z.

Since we know what the Distributive Property is, we can begin finding equivalent expressions.

Let's start by distribution:

[tex]3x+3(x+y)\\3x + 3x + 3y\\6x + 3y[/tex]

A is a correct option.

Let's check B and C.

Distribute:

[tex]3(x+x+y)\\3x+3x+3y\\6x+3y[/tex]

B is a correct option.

Distributing isn't needed for expression C.

[tex]3xy\neq 6x + 3y[/tex]

C is an incorrect option.

A and B are the correct options.
