I need some help idk why but I just can’t remember how to do this one
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.
Step-by-step explanation:
this line will cross the origin
to help I'm just going to explain something real quick.
make it into y intercept form (y=mx+b)
-2y=0-3x
y=3/2x +0
the m (3/2) is the slope
and b (0) is the y intercept
if you want to check it then imput a point on the line into the x and y variables
Formulate the recursive formula for the following geometric sequence.
{-16, 4, -1, ...} Show all your work please:)
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]

what is integers?
what is natural number?
1 An integer is a number that has no fractional part, and no digists after the decimal point. An integer can be positive, negative or zero. example 12, 34,-4,0 etc.
2. A natural number is a number that occurs commonly and obviously in nature. As such it is a whole, non -negative number. The set of natural numbers, denoted N, can be defined in either of two ways : N = (0,1,2,3,.......)
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.
Integers are all negative and positive counterparted whole numbers; e.g.... −4, −3, −2, −1, 0, 1, 2, 3, 4,...

. In an encyclopedia of language, the author presents five sentences that make a reasonable paragraph regardless of their order. The sentences are listed below. Mark had told him about the foxes. John looked out of the window. Could it be a fox? However, nobody had seen one for months. He thought he saw a shape in the bushes. In how many different orders can the five sentences be arranged?
Answer:
the 1st & last paras are fixed.
that leaves 3 to be put in any order
there are 3 choices for the 1st,
2 choices left for the 2nd
and just 1 choice for the last
multiply to get
3*2*1
= 6 ways
We want to find the total number of orders in which we can order the given sentences.
We will see that there are 120 different orders.
There are 5 sentences, let's define them as:
s₁ = Mark had told him about the foxes.s₂ = John looked out of the window.s₃ = Could it be a fox? s₄ = However, nobody had seen one for months.s₅ = He thought he saw a shape in the bushes.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.

This year, a small business had a total revenue of 33,500. If this is 34% more than their total revenue the previous year, what was their total revenue the previous year?
Final answer:
To find the previous year's total revenue, divide the current year's revenue by 1.34 since the current revenue is 34% higher than the previous year. The calculation shows that the previous year's revenue was $25,000.
Explanation:
The question asks us to find the total revenue of a small business for the previous year, given that the current year's revenue is 34% higher. To do this, we let x represent the revenue from the previous year. Since this year's revenue is 34% more than last year's, we have the equation:
1.34x = 33,500
To find the value of x, we divide both sides of the equation by 1.34:
x = 33,500 / 1.34
x = 25,000
Therefore, the total revenue for the previous year was $25,000.
Determine the next three terms in the following sequence:
1, 2, 5, 10,
a 17, 26, 37
b. 19, 30, 43
c50, 500, 25,000
d. 15, 25, 40
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.

Replace X with 1 and solve:

A park ranger at the top of a 700-meter station sees a fair that is 1800 meters from the base of the tower.
What is the angle of elevation in degrees?
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.
It is known that homing pigeons fly faster over land than over water. Assume that they fly 10 meters per second over land but only 8 meters per second over water. if a pigeon is located at the edge of a straight river 500 meters wide and must fly to its nest located 1300 meters away on the opposite side of the river, what path would minimize its flying time?
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.
Explanation: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.

A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $100 each day to operate the bank and $50 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most: 50x + 100 ≤ 600
Answer:
The restaurant Manager can afford 6 employees for the day.
Step-by-step explanation:
Manager can spend at most of $400.

Step-by-step explanation:
10. |-41|= 41
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

Please help!!!
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 )

Just failed hah stream fancy
Answer:
Answer is a^8/b^10
Option C
Step-by-step explanation:
((a²b-³)/(a-²b²))² where b and a are not equal zero
To solve this equation we start solving the equation from inside the bracket. And for simplicity we solve the numerator and solve the denominator before dividing them with each other. Now let get started
((a²b-³)/(a-²b²))²
Recall from indices that
a ^ -b = 1/a^b
I.e b-³ = 1/b³... We will apply this here.
((a²b-³)/(a-²b²))²
=((a²* 1/b³)/(b²*1/a²))²
=((a²/b³)/(b²/a²))²
Also recall that
(a/b) / (c/d) = (a/b) * (d/c)
Therefore
=((a²/b³)/(b²/a²))²
=(a²/b³ * a²/b²)²
Recall that: a^b * a^c = a^(b+c)
= (a ^ (2+2) / b ^ (2+3))²
= (a^4/b^5)²
Recall that: (a^b)^c = a^(b+c)
Therefore:
=™(a^4/b^5)²
=(a^(4*2)/b^(5*2))
= a^8/b^10

Dividing both the side by negative 3 we get
[tex]-21=1-2n\\2n=1+21\\2n=22\\n=\frac{22}{2} \\\therefore n=11[/tex]
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
Using distributive property A( B +C) = AB + AC we get
[tex]-3\times t + -3\times 5 + 4t + 2=8\\-3t-15+ 4t + 2=8\\t=8+15-2\\t=21\\\therefore t=21\\[/tex]
8. -8 - n = -3(2n -4)
Using distributive property A( B +C) = AB + AC we get
[tex]-8 - n = -3\times 2n - -3\times4\\-8-n=-6n+12\\\textrm{all the n terms to the left inside and the constant of the right-hand side}\\6n-n=8+12\\5n=20\\n=\frac{20}{5}\\ \therefore n= 4[/tex]
10. -4( 2 - y) + 3y = 3(y - 4)
Using distributive property A( B +C) = AB + AC we get
[tex]-4\times 2 --4\times y + 3y = 3\times y -3\times 4\\-8+4y+3y =3y-12\\\textrm{all the y terms to the left side and the constant to the right side}\\4y+3y-3y=-12+8\\4y=-4\\y=\frac{-4}{4}\\ \therefore y=-1[/tex]
