The cost of glass is:  £4

The cost of mug =  £2

Step-by-step explanation:

Let g be the number of glasses and

m be the number of mugs

[tex]3g+3m = 18\ \ \ \ \ Eqn\ 1\\6g+4m=32\ \ \ \ \ Eqn\ 2[/tex]

Multiplying equation 1 by 2

[tex]6g+6m=36\ \ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3

[tex]6g+6m - (6g+4m) = 36-32\\6g+6m-6g-4m=4\\2m=4[/tex]

Dividing both sides by 2

[tex]\frac{2m}{2} = \frac{4}{2}\\m = 2[/tex]

Putting m=2 in eqn 1

[tex]3g+3(2) = 18\\3g+6 = 18\\3g = 18-6\\3g = 12[/tex]

Dividing both sides by 3

[tex]\frac{3g}{3} = \frac{12}{3}\\g = 4[/tex]

Hence,

The cost of glass is:  £4

The cost of mug =  £2

x = - 3

y = -2

Step-by-step explanation:

3x - 8y = 7

x +2y = -7

We standardize the coefficient of one variable such that it addition will result to zero;

3x - 8y = 7

(x +2y = -7)4

Then multiply the one equation with a constant (this case 4) to get;

3x – 8y = 7

4x + 8y = - 28

We add the two equations;

3x – 8y = 7

+

4x + 8y = - 28

=

7x = - 21

x = -21 / 7

x = - 3

Now we evaluate y by replacing the value of x with -4 in one of the equation;

x +2y = -7

-3 +2y = -7

2y = -7 + 3

2y = - 4

y = -2

Remember that the speed is equal to divide the distance by the time

Let

s ---> the speed in miles per day

d ---> the distance in miles

t ---> the time in days

[tex]s=\frac{d}{t}[/tex]

The recursive formula for given sequence is:

[tex]a_n = -\frac{1}{4}a_{n-1}[/tex]

Step-by-step explanation:

Given sequence is:

-16, 4, -1, ...

First of all, we have to find the common ratio. common ratio is the ratio between two consecutive terms of a geometric sequence

Here

[tex]a_1 = -16\\a_2 = 4\\a_3 = -1\\Now\\r = \frac{a_2}{a_1} = \frac{4}{-16} = -\frac{1}{4}\\r = \frac{a_3}{a_2} = \frac{-1}{4} = -\frac{1}{4}[/tex]

The recursive of geometric sequence is:

[tex]a_n = r * a_{n-1}[/tex]

Putting the value of r

[tex]a_n = -\frac{1}{4}a_{n-1}[/tex]

Hence,

The recursive formula for given sequence is:

[tex]a_n = -\frac{1}{4}a_{n-1}[/tex]

The correct sequence is a. 17, 26, 37.

To determine the next three terms in the sequence, we must first identify the pattern governing the sequence. Let's examine the differences between consecutive terms:

- The difference between the second term (2) and the first term (1) is 1.

- The difference between the third term (5) and the second term (2) is 3.

- The difference between the fourth term (10) and the third term (5) is 5.

- The difference between the fifth term (17) and the fourth term (10) is 7.

We can see that the differences between consecutive terms are increasing by 2 each time. This suggests that the sequence is generated by adding consecutive odd numbers to the previous term. To find the next terms, we continue this pattern:

- The sixth term will be the fifth term (17) plus the next odd number (9), which is 17 + 9 = 26.

- The seventh term will be the sixth term (26) plus the next odd number (11), which is 26 + 11 = 37.

- The eighth term will be the seventh term (37) plus the next odd number (13), which is 37 + 13 = 50.

Therefore, the next three terms of the sequence are 26, 37, and 50, confirming option a as the correct answer.

Because the equation contains an absolute value, the shape of the graph would be a V,.

The Y intercept is -1, so this would be the lowest point on the graph.

Replace X with 1 and solve:

y = 2(1) -1 = 2-1 = 1, so another point would be (1,1) and another point would be (-1,1)  ( Absolute value would use both -1 and 1 as the same).

Make 3 points on the graph:

(-1,1) (1,1) ans (0,-1) and draw lines through them.

Final answer:

To find the angle of elevation, we can use the concept of tangent. The angle of elevation is approximately 67.7 degrees.

Explanation:

To find the angle of elevation, we can use the concept of tangent.

Tan(Angel of Elevation) = Opposite/Adjacent

Here, the opposite side is the height of the fair, which is 1800 meters, and the adjacent side is the height of the station, which is 700 meters.

Tan(Angel of Elevation) = 1800/700

Angel of Elevation = tan-1(1800/700)

Using a calculator, the angle of elevation is approximately 67.7 degrees.

Answer:

4 meters longer.

Step-by-step explanation:

Amit built a sandcastle that measured 600 cm by 600 cm i.e. 6 meters by 6 meters.

Therefore, its perimeter is 2(6 + 6) = 24 meters

Now, afterward, he decided to change the castle size, making it 8 meters by 6 meters.

Therefore, its perimeter is 2(6 + 8) = 28 meters

Therefore, the perimeter of the new castle is increased by (28 - 24) = 4 meters.

If Amit dug a moat around his castle then the new moat will be 4 meters longer than the old one. (Answer)

As the moat is dug around the castle, its length will be the same as the perimeter of the castle.

Answer:

The next two terms for the geometric sequence are - 108 and - 324.

Step-by-step explanation:

1. Let's find the next two terms for the geometric sequence which first three terms are as follows:

- 4, 12, - 36.....

Aₓ = Aₓ₋₁ * 3 ; A₁ = - 4

A₁ = - 4

A₂ = A₁ * 3 = - 4 * 3 = - 12

A₃ = A₂ * 3 = - 12 * 3 = - 36

A₄ = A₃ * 3 = - 36 * 3 = - 108

A₅ = A₄ * 3 = - 108  * 3 = - 324

The next two terms for the geometric sequence are - 108 and - 324.

12. -|1.5|= -1.5

Answer:

A.) 41

B.) -1.5

Step-by-step explanation:

Absolute value means to make whatever that is inside positive

10.) The absolute value of negative 41 would simply be positive 41

11.) Since the negative sign is on the outside of the absolute value, you do the absolute value of everything inside then apply a negative sign. Absolute value of 1.5 is just 1.5 because it's already positive. Then apply the negative sign, which would make it -1.5

y=3x/2

Step-by-step explanation:

first you want to get the -2y alone so you move the 3x. since it's adding now the opposite of addition is subtraction. now your left with -2y= -3x. since your trying to solve for y now you divide -2 on both sides and your gonna be left with y= -3x/-2. since their both negatives it turns to postive. that's why the answer would be y= 3x/2.

Answer:

C

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x) by c units

• If c > 0 then shift c units up

• If c < 0 then shift c units down

The red graph is a vertical translation f(x) of 3 units down

Thus

y = f(x) - 3 ( add 3 to both sides )

y + 3 = f(x) ← equation of red graph

We will see that there are 120 different orders.

There are 5 sentences, let's define them as:

We know that we can order these in any order, so we can think of the situation as 5 empty slots, in each slot, we can put one of the previous statements.

Let's count the number of options for each one of these slots.

On the first one, we have 5 options (5 sentences)

On the second one we have 4, because we already used one on the first slot.

On the third, we have 3 options.

On the fourth, we have 2 options.

On the fifth, we have 1 option.

The total number of combinations is given by the product of these numbers of options.

Step-by-step explanation:

we know that

The equation of the parent function f(x) (red graph) is

[tex]f(x)=x^{2}[/tex]

This is a vertical parabola open upward

The vertex is the point (0,0) (the origin)

The function g(x) (blue graph) is a vertical parabola open upward

The vertex is the point (-5,0)

The transformation of f(x) to g(x) has the following rule

f(x) -----> g(x)

18.55, lines m and n are parallel and t is the transversal. If ∠1 = 130o, find the measures of the other angles and give reasons.

Step-by-step explanation:

The measure of angle 8 will be 130° since it corresponds to angle 1, and their measures are equal because lines m and n are parallel.

To find the measure of angle 8 when lines m and n are parallel, and the measure of angle 1 is 130°, it's important to understand the concept of corresponding angles in the context of parallel lines. Corresponding angles are equal when two lines are parallel. Given that angle 1 is 130°, and assuming that angle 1 and angle 8 are corresponding angles (since the question does not specify their positions), the measure of angle 8 is also 130°.
