can you tell me if they are proportional or nonproportional

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

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.

Answer:

The answer is y = 6.

Step-by-step explanation:

Given:

RS = [tex]3y+41[/tex], ST = [tex]18y-76[/tex] and RT = 91.

Now, to find the [tex]y[/tex].

According to question add the equations:

RS + ST = RT

[tex]3y+41+18y-76=91[/tex]

Adding the numbers and variables in L.H.S.

[tex]3y+18y-76+41=91[/tex]

[tex]21y-35=91[/tex]

Adding 35 on both sides:

[tex]21y-35+35=91+35[/tex]

[tex]21y=126[/tex]

Dividing both sides by 21:

[tex]21y\div 21=126\div 21[/tex]

[tex]y=6[/tex]

Therefore, the answer is y = 6.

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]

Answer:

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.

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.

The homing pigeon will minimize its flying time by flying straight across the river, then directly to its nest. The time to fly this route would be 142.5 seconds.

The homing pigeon's path that will minimize its flying time would-be one where it flies straight across the river and then flies directly to its nest. The total time can be calculated by adding the time it flies over water and the time it flies over land. Initially, calculating the flying time over water, if the river is 500 meters wide, the time will be the distance divided by speed which equals 500m/8m/s = 62.5s . Now the land distance is the total distance minus the width of the river, so it would be 1300m – 500m = 800m. The time to cross this distance will be 800m/10m/s = 80s. Hence, adding both times, total flying time will be 62.5s + 80s = 142.5s. Therefore, the shortest path is firstly, flying straight across the river, and then straight towards its nest.

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.

4. -g + 2(3 + g) = -4(g + 1)

First we will open the bracket by distributive property A( B +C) = AB + AC

[tex]-g+2\times 3 + 2\times g = -4\times g + -4\times 1\\-g+6+ 2g=-4g-4\\\textrm{we will take all the g term the left side and the constant to the right side}\\4g-g+2g=-6-4\\5g=-10\\g=\frac{-10}{5}\\\therefore g=-2[/tex]

6.-3(t +5 ) + (4t + 2) = 8

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.

Natural numbers include 1, 2, 3, 4...; they are numbers you normally count and will go onto infinity and beyond. ZERO IS NOT A NATURAL NUMBER BECAUSE IT IS NEUTRAL.

Answer:

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°.

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.
