The slope of the line is that passing through the points  (-1,-3) and (1,3) is m = 2

From the graph, we have to find the two points to find the slope of the line

The two points are (-1,-3) and (1,1)

The slope of the line m = [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]
Where m is the slope of the line

[tex](x_{1} ,y_{1})[/tex] are the coordinates of first point

[tex](x_{2} ,y_{2})[/tex] are the coordinates of second point

substitute the values in the equation of slope of the line

The slope of the line m =[tex]\frac{1-(-3)}{1-(-1)}[/tex]

= 4/2

= 2

Hence, the slope of the line is that passing through the points  (-1,-3) and (1,3) is m = 2

It is to be noted that the information for the completed table is given accordingly to show the perimeters in millimeters and in centimeters.

Perimeter simply refers to the total or sum of all the sides of a geometric shape. Note that the perimeter in units is obtained by counting the number of rectangles.

In the case of A:

Perimeter in Units = 10 Units.

Length is 60mm and width is 40mm
Perimeter = 30 + 20 + 30 + 20 = 100mm; and 10 cm

Recall that I cm = 10mm.

Hence, 100 /10 = 10 cm.

In the case of shape B:
Perimeter in Units = 41 Units.

Length is 400mm (that is 200 + 200)

Breath is 40mm (20 + 20)

Perimeter therefore is:

400 + 40 = 440mm
Perimeter in cm = 44

Recall, 10mm = 1cm

In the case of shape C:

Perimeter in Units = 36 Units.

Length is 10cm (that is 5 + 5)

Breath is 14mm (7 + 7)

Perimeter therefore is:

10+ 14 = 24cm
Perimeter in mm= 240

Recall, 10mm = 1cm

In the case of Shape D:

Perimeter in Units = 51 Units.

Length is 200mm (that is 100 + 100)

Breath is 100mm (50 + 50)

Perimeter therefore is:

200 + 100 = 300mm
Perimeter in cm= 230

Recall, 10mm = 1cm

In the case of Shape D:

Perimeter in Units = 53 Units.

Length is 260mm (that is 130 + 130)

Breath is 80mm (40 + 40)

Perimeter therefore is:

260 + 80 = 340mm
Perimeter in cm= 34

Answer:

j = 1

Step-by-step explanation:

calculate the slope m between the 2 points and equate to - [tex]\frac{7}{10}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, j ) and (x₂, y₂ ) = (5, - 6 )

m = [tex]\frac{-6-j}{5-(-5)}[/tex] = [tex]\frac{-6-j}{5+5}[/tex] = [tex]\frac{-6-j}{10}[/tex]

then equating gives

[tex]\frac{-6-j}{10}[/tex] = - [tex]\frac{7}{10}[/tex] ( cross- multiply )

10(- 6 - j) = - 70 ( divide both sides by 10 )

- 6 - j = - 7 ( add 6 to both sides )

A mathematical expression known as an algebraic expression includes variables, constants, and algebraic operations (addition, subtraction, etc.). Expressions include terms. Here, y=3x.

The idea behind algebraic expressions is to represent numbers using letters or alphabets rather than giving their exact values. In algebraic basics, we learned how to express an unknown number using letters like x, y, and z. We will refer to these letters as variables from now on. An algebraic expression may have both constants and variables. Any amount that is added to a variable before it is multiplied by another is known as a coefficient.

"Write an equation that represents the pattern in the table

x 4,5,6,7,8

y 12,15,18,21,24 y = __ x"

Answer: See attached and/or view below.

Step-by-step explanation:

      Since we are given the equation, we can plug the values into it and solve for the unknown. We will solve by isolating the variable and using reverse operations.

      x = 1, y = 34

2x + y = 36

2(1) + y = 36

2 + y = 36

y = 34

      x = -2, y = 40

2x + y = 36

2(-2) + y = 36

-4 + y = 36

y = 40

      y = 18, x = 9

2x + y = 36

2x + (18) = 36

2x = 18

Answer:

m<1 = 159° m<2 = 21° m<4 = 21°

Step-by-step explanation:

Since angle measure 3 was found, seeing that 3 and 1 are vertical angles (congruent) they equal the same, meaning angle measure 1 is also 159°. Also seeing that angle measure 3 and 2 are supplementary angles (2 or more angles that add up to 180°) subtracting 159° will give you 21°. Once again there are another set of verital angles, 2 and 4 making 4 also 21°

Answer:

35

Step-by-step explanation:

The consecutive interior angles are supplementary, so:

The unit rate of ounces of water per cup of flour for this situation is; 3 ounces per cups

From the given graph, we are expected to find the unit rate of ounces of water per cup of flour for the situation.

Now, to find the unit rate , all we need to do is to pick two coordinates on the line graph and find the slope. Thus;

Slope = (y2 - y1)/(x2 - x1)

Slope of graph = (12 - 9)/(4 - 3)

Slope = 3/1

Slope = 3

Let us pick another two points to verify;

Slope = (6 - 3)/(2 - 1)

Given picture is not a graph of inequality y < 6x + 1

In this question, we have been given a graph.

We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.

We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.

This graph represents a shaded region below dotted line. This means, this is the graph of inequality.

From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)

If we find the x and y-intercept of y = 6x + 1 then it would be,

x - intercept = (-1/6 , 0)

y - intercept = (0, 1)

This means, given picture is not a graph of inequality y < 6x + 1

If the radius to the inside of the shell is 4 millimeters and the radius to the outside of the shell is 4.3 millimeters. the volume of the shell is 19π mm³.

v = 4 / 3πr³

dv =4 / 3π (3r²) dr

Where:

r= radius = 4 cm

dr = 4.3 -4 = 0.3

Hence,

dv = 4 / 3π (16) 3/10

dv =4 / 3π(16) 0.3

Answer: x = 80°, y = 50°

Step-by-step explanation:

We have an isosceles triangle.

As you can see, 130° lies on a straight line. A straight line = 180°.

The base angles of an isosceles triangle are equal. This means 180° - 130° = y.

So, y = 50°.

The total measures of any triangle is 180 degrees.

The total measure for the base angles here 100 degrees. That is, 50° + 50° =

By using a rotation rule, the image of point P = (- 4, 1) after rotating 180° counterclockwise using center (- 3, 0) is equal to point P'(x, y) = (- 2, 1).

In this problem we find the case of a point that must be rotated 180° counterclockwise (+ 180°) about the point (- 3, 0). Rotation is a kind of rigid transformation, that is, a kind of transformation applied on a point such that Euclidean distance is conserved. The rotation formula for a point P(x, y) = (x, y) around the center O(x, y) = (Ox, Oy) is introduced below:

P'(x, y) = (Ox + (x - Ox) · cos θ - (y - Oy) · sin θ, Oy + (x - Ox) · sin θ + (y - Oy) · cos θ)

Where θ is the angle of rotation.

If we know that O(x, y) = (- 3, 0), P(x, y) = (- 4, 1) and θ = 180°, then the coordinates of the image are:

P'(x, y) = (- 3 + [- 4 - (- 3)] · cos 180° - (1 - 0) · sin 180°, 0 + [- 4 - (- 3)] · sin 180° + (1 - 0) · cos 180°)

P'(x, y) = (- 3 - [- 4 - (- 3)], - 1)

P'(x, y) = (- 3 - (- 1), - 1)

P'(x, y) = (- 2, - 1)

The coordinates of the image are P'(x, y) = (- 2, 1).
