Find the linear equation that represents the scenario.
y= 235x + 15
y= 4x + 955
y= 15x + 235
y= 3x + 705

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26

Answer:

The graph of ordered pairs that shows a proportional relationship is: Graph 1

A proportional relationship is defined as a relationship between two variables where the ratio of the variables is always the same. In other words, one variable is always a constant multiple of the other variable.

Graph 1: The rate of change of y with x for the two points are:

m = -2/1 = -2

m = -4/2 = -2

Graph 2: The rate of change of y with x for the two points are:

m = 3/1 = 3

m = -2/-2 = 1

Graph 3: The rate of change of y with x for the two points are:

m = -2/1 = -2

m = 1/-3 = --1/3

Graph 4:  The rate of change of y with x for the two points are:

m = 1/2

m = 3/5

Thus, the only one that represents a proportional relationship is Graph 1

Answer:

9

Step-by-step explanation:

a triangle is bacicly half of a rectangle so 3 x 6 is 18 but since it's just half, you divide by 2 and you get 9!

Step-by-step explanation:

Phytagoras Theorem :

c² = a² + b²

c² = 3² + 6²

c² = 9 + 36

c² = 45

c = √45

So, the exact length og the third side is √45

Answer:

7

Step-by-step explanation:

Three more than twice b, where b equals 2, is calculated by doubling b to get 4 and then adding 3 to reach a total of 7.

Given that a = 10 and b = 2, we need to calculate what 'three more than twice b' is.

First, let's find twice b:

Now, we add three to get 'three more than twice b':

Therefore, 'three more than twice b' is 7.

Answer:

49x^2 - 9 = 0

As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:

49 = 7^2

9 = 3^2

x^2 = (x)^2

so...

(7x - 3)(7x + 3) = 0

7x - 3 = 0 7x + 3 = 0

Answer: The area of the shaded sectors is 35.3 square kilometres

Step-by-step explanation: What we have here is a circle with center Z. Two sectors have been formed which are ZVW and ZYX. A careful observation reveals that both sectors are similar. If WY passes through the center Z then WY is a diameter. The same applies to VX, since it also passes through the center, therefore it is a diameter. Both lines intersect at the center, that makes both sectors to have the same radii which is  5.3 km and same applies to the angle subtended at the center of the sector, both angles are opposite angles formed by intersecting lines (opposite angles formed by intersecting lines are equal). On a straight line WY, the sum of angles ∠WZX and ∠YZX equals 180 degrees (Sum of angles on a straight line equals 180). Therefore;

WZX + YZX = 180

108 + YZX = 180

Subtract 180 from both sides of the equation

YZX = 72°

Therefore the area of shaded sector YZX is given as;

Area of a sector = (∅/360) x πr²

Where ∅ is 72, and r is 5.3

Area of sector = (72/360) x 3.14 x 5.3²

Area of sector = 0.2 x 3.14 x 28.09

Area of sector = 17.64

Having in mind that both sectors are similar (the same radii and the same central angle), the area of the shaded sectors shall be equal to 17.64 times 2 and that equals 35.28. (That is approximately 35.3 to the nearest tenth)

The area of the shaded sectors therefore is 35.3 square kilometres (35.3 km²)

Answer:

Area of the shaded region ≈ 35.3 km²

Step-by-step explanation:

Area of a sector = ∅/360 × πr²

angle on a straight line  = 180°

Therefore,

∠vzw = 180 - 108 = 72°

∠yzx = 180 - 108 = 72°

Area = 72 /360 × 22/7 × 5.3²

Area = 72 /360 × 22/7 × 28.09

Area = 44494.56/2520

Area = 17.656571429

Area = 17.66 km²

The area is one portion of the shaded part , the area of the 2 shaded sector will be

Area of zvw  + Area of zyx

Both area are same . They have same radius and the same angle.

Area of the shaded region = 17.66 + 17.66

Area of the shaded region ≈ 35.3 km²

Answer:

-1215.

Step-by-step explanation:

For a geometric sequence:

nth term = a1 r^(n-1)

The first term a1 = 5 and the common ratio r  = -15/5 = -3.

So 6th term = 5 * (-3)^(6-1)

=  5 * (-3)^5

= -1215.

The 6th term in this geometric sequence should be considered as the -1215.

The following formula should be used for the same.

nth term = [tex]a_1\ r^{(n-1)[/tex]

Here,

The first term a1 = 5

and the common ratio r  = [tex]-15/5[/tex]= -3.

So 6th term should be

[tex]= 5 \times (-3)^{(6-1)}[/tex]

[tex]= 5 \times (-3)^5[/tex]

= -1215

Hence, The 6th term in this geometric sequence should be considered as the -1215.

There is an isosceles triangle.

The triangle is like two right triangles put together.

To find out the height of the triangle, we remove the other right triangle and we use the other triangle to find the height using the Pythagorean theorem.

Phytagoras Theorem :

b² = c² - a²

The slope between the points (0, –5) and (–9,1) is -2/3, which is found using the slope formula. Positive slopes rise, negative slopes fall, and zero slopes are horizontal lines.

To find the slope of a line passing through two points (0, –5) and (–9,1), we use the formula for the slope (m), which is m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

Substituting the given points into the formula, we get m = (1 - (-5)) / (-9 - 0), which simplifies to m = (1 + 5) / (-9), and further simplifies to m = 6 / (-9), resulting in a slope of m = -2/3.

Regarding slope and its characteristics on a graph, a positive slope means the line rises as it moves from left to right, a negative slope means the line falls as it moves from left to right, and a zero slope indicates a horizontal line.

(If you are using MathsWatch) For this question the triangle gets smaller so i'm not sure why it says Enlarge the triangle.

To enlarge the triangle by a scale factor of 0.5 with a center of enlargement at (3,1), multiply the coordinates of each vertex by 0.5 and add 3 to the x-coordinate and 1 to the y-coordinate.

To enlarge the triangle by a scale factor of 0.5 with a center of enlargement at (3,1), you will need to multiply the x-coordinate and y-coordinate of each vertex of the triangle by 0.5 and then add 3 to the x-coordinate and 1 to the y-coordinate. This will give you the new coordinates for the enlarged triangle. For example, if the original triangle has vertices A(1,2), B(3,4), and C(5,6), the new coordinates for the enlarged triangle will be A'(3.5,2.5), B'(4.5,3.5), and C'(5.5,4.5).
