Step-by-step explanation:

The 3 pounds of tomato cost will cost £4.5.

Pound and lbs. are practically synonyms for one another. The popular shorthand used to denote pounds is "lbs," which stands for libra. The pound is the real unit of measurement.

The cost of 7 lbs of tomatoes is £10.50.

then, the cost of 1 lbs of tomatoes is,

10.50/7 = 1.5

The cost of 1 lbs of tomatoes is 1.5 lbs.

Since, 1 lbs = 1 pound

Thus, the total cost of 3 pounds of tomatoes is,

3×1.5 = 4.5

Therefore, the  3 pounds of tomatoes will cost £4.5.

Graphs such as line and tape diagrams can be used to represent equations.

Diagram (a)

In this diagram, all the x boxes (5 boxes) are shaded, while all the y boxes (3) are shaded.

So, the equation is:

[tex]y = \frac{3}{5}x[/tex]

Express as decimal

[tex]y = 0.6x[/tex]

The ratio (0.6) is less than 1.

So, it represents a decrement.

And the decrement (d) is:

[tex]d = 1 - 0.6[/tex]

[tex]d =0.4[/tex]

Diagram (b)

In this diagram, all the x boxes (6 boxes) are shaded, while part of  the y boxes (6 of the 11) are shaded.

So, the equation is:

[tex]y = \frac{11}{6}x[/tex]

Express as decimal

[tex]y = 1.83x[/tex]

The ratio (1.83) is greater than 1.

So, it represents an increment.

And the increment (d) is:

[tex]d = 1.83 - 1[/tex]

[tex]d = 0.83[/tex]

Answer:

The two numbers are 14 and 4

Step-by-step explanation:

Let x and y be the two numbers

x+y = 18

x-y = 10

Add the two equations

x+y = 18

x-y = 10

------------------

2x    = 28

Divide by 2

2x/2 = 28/2

x = 14

Now find the other number

x+y =18

14+y = 18

y = 18-14

y=4

The two numbers are 14 and 4

The rate of change of [x] with respect to [y] will be 4.5.

Rate is the measure of rate of change of variable [y] with respect to variable [x]. Mathematically -

Rate [r] = dy/dx

Given is a table that shows a linear relationship between x and y.

In order to find the rate of change of [y] with respect to [x], we have to select any two coordinates from the given ones. Suppose that we take

(- 20, 96) and (- 12, 60).

The rate of change of [y] with respect to [x] can be calculated as follows -

r = (y₂ - y₁)/(x₂ - x₁)

r = (60 - 96)/(-12 + 20)

r = - 36/8

r = 4.5

The rate of change will be 4.5.

Therefore, the rate of change of [x] with respect to [y] will be 4.5.

Answer:

A. Rectangle

Step-by-step explanation:

Shown in the attachment are the four points graphed on a coordinate plane.

We can see that the opposite sides are parallel to each other and have the same length.

The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.

The answer cannot be C. Rhombus because of the same reason as above.

The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.

Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

Answer:

90

Step-by-step explanation:

because m3+m4 = 90 and m2 and m4 are corresponding angles. therefore m4 = m2 so m3 +m2 = 90

Answer:

Option (1)

Step-by-step explanation:

Coordinates of the vertices of ΔPQR,

P → (2, 5)

Q → (6, 2)

R → (2, 2)

Now vertices of the transformed triangle,

P' → (2, -5)

Q' → (6, -2)

R' → (2, -2)

If we compare P and P' relation between their coordinates is,

P(2, 5) → P'(2, -5)

(x, y) → (x, -y)

Which reveals that triangle PQR has been reflected across x-axis to form the image triangle P'Q'R'.

Option (1) is the answer.
