Answer:

y = -1x - 4

Step-by-step explanation:

ROC = -1 (same thing as you're slope)

b = y - intercept = -4

y = -1x - 4

Answer:

[tex]y=-x-4[/tex]

Step-by-step explanation:

The rate of change is the same as the slope (m variable), and in this sense you don't have to write out -1x, you can just keep it at -x. The point you are given is the point where the line crosses the y axis, which is called the y-intercept and is the variable b in your equation. This is because the x coordinate is zero, so it has to be where the line crosses the y axis. Just put that -4 in as your b variable, and there's your answer!

Answer:

b

Step-by-step explanation:

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

3 (60) = will

180 = WILL

The solution is

The weight of Brenda = 60 pounds

The weight of Will = 180 pounds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the weight of Brenda be = x

Let the weight of Will be = y

Now , Will weighs three times as much as Brenda

Substituting the values in the equation , we get

y = 3x   be equation (1)

And , the weight of Will + weight of Brenda = 240 pounds

So , x + y = 240   be equation (2)

Substituting the value of y from equation (1) in equation (2) , we get

x + 3x = 240

On simplifying the equation , we get

4x = 240

Divide by 4 on both sides of the equation , we get

x = 60 pounds

So , the weight of Brenda is 60 pounds

Substitute the value of x in equation (1) , we get

y = 3x

y = 3 x 60

y = 180 pounds

So , the weight of Will is 180 pounds

Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Step-by-step explanation:

Answer:

18 flowers for each area

Step-by-step explanation:

Do the amount of flowers divided by the amount of areas there are.

ie: 54/3

The third fraction or one-third of 54 will be 18 thus, 18 flowers have for each planting location.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variables called division.

For example 4/8

As per the given,

Total number of flowers = 54

54 flowers need to divide into three parts,

54/3 = 18 flowers.

Hence "The third fraction or one-third of 54 will be 18 thus, 18 flowers have for each planting location".

Answer: [tex]\sqrt{7}[/tex] divided by 2

Step-by-step explanation:

[tex]\sqrt{4}[/tex] becomes 2 .2 [tex]\sqrt{28}[/tex] becomes 2 x 2[tex]\sqrt{7}[/tex], which would equal 4 [tex]\sqrt{7}[/tex]. Then I think you simplify the 2 and four ( 2/4 ), making the equation 1/2 x [tex]\sqrt{7}[/tex]. 1 x [tex]\sqrt{7}[/tex] would equal [tex]\sqrt{7}[/tex]. So I think the answer would be [tex]\sqrt{7}[/tex] divided by 2.

Answer:

[tex]T = 100[/tex]

Step-by-step explanation:

See attachment for parallelogram TRIK

Given

[tex]T = 5x[/tex]

[tex]I = 2(x + 30)[/tex]

Required

Determine T

Because T and I are opposite angles of the parallelogram, then they are congruent.

i.e.

[tex]T = I[/tex]

Substitute values for T and I

[tex]5x = 2(x + 30)[/tex]

Open bracket

[tex]5x = 2x + 60[/tex]

Collect Like Terms

[tex]5x - 2x = 60[/tex]

[tex]3x = 60[/tex]

Solve for x

[tex]x = \frac{60}{3}[/tex]

[tex]x =20[/tex]

Recall that:

[tex]T = 5x[/tex]

[tex]T = 5 * 20[/tex]

[tex]T = 100[/tex]

Answer:

Length = 18

Step-by-step explanation:

Length= 2w - 4

Perimeter= 58

Perimeter= 2L + 2w

58 = 2(2w-4) + 2w

58 = 4w -8 + 2w

58 = 6w - 8

66 = 6w

11 = w

Plug in width to find the variable L

58 = 2L + 2(11)

58 = 2L + 22

36 = 2L

18 = L
