Answer:

The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

Step-by-step explanation:

Given the rule

''y is 3 times the value of x".

It means

y = 3x

comparing with the slope-intercept form of the line equation

y = mx+b

where y is the slope and b is the intercept

so,

The slope of y = 3x will be: m = 3

The y-intercept of  y = 3x will be: b = 0

CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)

Taking two points

(0, 0)

(2, 6)

Finding the slope between (0, 0) and (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [6 - 0] / [2 - 0]

                = 6 / 2

               = 3

Thus, the slope of the line = m = 3

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function

y = mx+b

y = 3x+0

y = 3x

Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

Answer:

It's the bottom right graph.

Answer:

y = - 1.25x + 9

Step-by-step explanation:

A(0,9)  B(4,9)   C(4,4)

AB² = (4-0)² + (9-9)² = 16

AC² = (4-0)² + (4-9)² = 41

BC² = (4-4)² + (4-9)² = 25

AC is hypotenuse with y interception of 9

slope = 5/4 = -1.25

equation: y = - 1.25x + 9

Answer: $36.9043

Step-by-step explanation:

Given that :

Cost of handbag = $20

Cost of umbrella = $5.99

Cost of scarf = $8.50

Sales tax = 7% = 0.07

Sales tax = 0.07 * (20 + 5.99 + 8.50)

Sales tax = 0.07 * 34.49

Sales tax = $2.4143

Total cost of purchase :

Sales tax + cost of items

$2.4143 + $34.49

= $36.9043

Answer:

(a) and (d) will be done by regrouping

Step-by-step explanation:

Solution will be done by regrouping if unit term of term which is subtracted is greater then the term which subtracts.

(a) 65 -56, since the unit term of 65 is 5 and of 56 is 6

as the unit terms of 56 is greater than unit term of 65

Thus solution will be done by regrouping

⇒ 65 -56 = 9

(b) 28 -15, since the unit term of 28 is 8 and of 15 is 5

as the unit terms of 28 is greater than unit term of 15

Thus solution will not be done by regrouping

⇒ 28 -15 = 13

(c) 16 -6, since the unit term of 16 is 6 and of 6 is 6

as the unit terms of 16 is equal to unit term of 6

Thus solution will not be done by regrouping

⇒ 16 -6 = 10

(d) 74-38 , since the unit term of 74 is 4 and of 38 is 8

as the unit terms of 38 is greater than unit term of 74

Thus solution will be done by regrouping

⇒ 74-38 = 36

Answer:

So area of square is: a^2

5^2=25cm^2

4/9 x 25 = 100/9

Area of picture is: 11.11 cm^2

Step-by-step explanation:

The area of the square will be equal to 11.11 square centimetres.

The space covered by the two-dimensional object on a plane is called as an area. The space covered by the square in a two-dimensional plane is called the area of the square.

The square is a quadrilateral having four sides and all the sides of the square are equal to each other.

The the area of the square is calculated as,

a² = 5²=25 cm²

The picture area is 4/9 of the total

area.

4/9 x 25 = 100/9

Answer:28 dollar

Step-by-step explanation: 140 x (20/100)= 28 dollar

140-28= 112 the price after the sale

Answer: you will save $28.

Step-by-step explanation:

To find a percent of a number you have to turn the percent into a decimal. For example you would turn 20% into 0.20 then multiply this by 140. After doing this you will find out that 20% of 140 is 28.

Answer:

d = 1

t = 16

Step-by-step explanation:

Television = t

DVD = d

4t + 6d = 70

2t + 5d = 37

2t + 5d = 37

2t = 37 - 5d

2t/2 = 37/2 - 5d/2

t = 18.5 - 5/2d

4t + 6d = 70

4(18.5 - 5/2d) + 6d = 70

74 - 10d + 6d = 70

-4d = -74 + 70

-4d = -4

-4d/-4 = -4/-4

d = 1

2t + 5d = 37

2t + 5(1) = 37

2t + 5 = 37

2t = 37 - 5

2t = 32

2t/2 = 32/2

t = 16

Check: d = 1; t = 16

4t + 6d = 70

4(16) + 6(1) = 70

64 + 6 = 70

70 = 70

2t + 5d = 37

2(16) + 5(1) = 37

32 + 5 = 37

37 = 37

Answer:

A quadratic equation is some thing like

(x+2)^2

or

(x+2)(x+5)

In order to solve them, the most basic method is the FOIL method

F-First

O-Outside

I-Inner

L-Last

So for example

(x+2)^2

Which is basically

(x+2)(x+2)

So the first is the 2 Xs

(x+2)(x+2)

x*x=x^2

The outer is the x and the 2,

(x+2)(x+2)

2*x=2x

Now the Inner which is the 2 and the x

(x+2)(x+2)

2*x=2x

And finally the last  which is the 2 and the second 2

(x+2)(x+2)

2*2=4

Now add them all up

X^2+2x+2x+4

Combine like terms

x^2+4x+4

There you have it

Do the same with every other quadratic equation
