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:  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.

Perimeter of rectangle:

length×2 + wide×

=Total perimeter



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.

Answer:   7C+84Step-by-step explanation:Distributive property : a(b+c) = ab+ac , where a,b,c, are any expressions.Given : A restaurant uses C cups of flour for baking rolls and 12 cups of flour for baking pies.i.e. Number of cups of flour used for baking rolls per day = CNumber of cups of flour used for baking pies per day = 12Total flour used each day= C+12Now , total flour used in 7 days = 7 x (Total flour used each day)= 7 (C+12)= 7C +7 (12)   [By distributive property]= 7C+84Hence, the expression for how much flour the restaurant uses in seven days : 7C+84

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:

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.

Hope it helps. Happy New Month. Have a nice week.

Answer:

The correct options are C and D

Important information:

Meg laid 15 tiles in 50 minutes.

Jessica worked for 85 minutes at a faster rate per tile than Meg.

Step-by-step explanation:

The rate per tile of Meg is:

Rate = time/no. of tiles

Rate = 50/15

Rate = 3.333333...etc

Calculate the rates per tile for each option.

85/20 = 4.25

85/24 = 3.54167...

85/28 = 3.0357

3/1 = 3

4/1 = 4

From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.

Therefore, the correct options are C and D.

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:

Step-by-step explanation:

1. 14/33

2. 5/7

3. 1/4

Answer:

14/33, 5/7, and 1/4

Step-by-step explanation:

When multiplying fractions, there are three steps to follow.

1. Multiply the numerators together

2. Multiply the denominators together

3. Put the numerator product as the numerator and the denominator product as the denominator

4. Find the GCF and equalize the fraction

let’s do this with number 1. We have 2/3 and 7/11. First, we multiply the numerators.
2 x 7 = 14

Next, we multiply the denominators:

3 x 11 = 33

Now let’s see if there are any common factors of 14 and 33:

14: 1, 2, 7, 14

33: 1, 3, 11, 33

Since there are no common factors, 14/33 is our final answer.

next problem: 6/7 and 5/6.

Multiply 6 and 5 = 30 (as numerators)

Multiply 7 x 6 = 42 (as denominators)

List the factors:

30: 1, 2, 3, 5, 6, 10, 15, 30

42: 1, 2, 6, 7, 21, 42

Since the biggest factor of both is 6, we can factor that out:

6(5)/6(7)

5/7 is our final answer

last problem: 2/5 and 5/8

Multiply 2 and 5 = 10

Multiply 5 and 8 = 40

List the factors:

10: 1, 2, 5, 10

40: 1, 2, 4, 5, 8, 10, 20, 40

Since the biggest factor of both is 10, we factor that out:

10(1)/10(4)

1/4 is our final answer.
