Answer:

Step-by-step explanation:
Both sequences have a common difference between consecutive terms, that is
2 - 1 = 3 - 2 = 4 - 3 = 1
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 1 , thus
[tex]a_{n}[/tex] = 1 + n - 1 = n
--------------------------------------------------------------------
Similarly
d = 9 - 5 = 13 - 9 = 17 - 13 = 4 and a₁ = 5 , then
[tex]a_{n}[/tex] = 5 + 4(n - 1) = 5 + 4n - 4 = 4n + 1

Suppose that the function f(x)=5.32+0.80x represents the cost of mailing an
object that weighs x pounds. How much would it cost to mail an object that
weighs 35 pounds?
Answer:
$33.32
Step-by-step explanation:
f(x)=5.32+0.80(35)
=5.32+28
=$33.32
The required cost of mail of the object of 35 pounds is $33.32.
Given that,
f(x)=5.32+0.80x represents the cost of mailing an object that weighs x pounds.
To determine how much would it cost to mail an object that weighs 35 pounds.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
function f(x) represents the cost of mail of x weigh object,
Now for the x = 35
f(x) = 5.32 + 0.80 * 35
f(x) = 5.32 + 28
f(x) = 33.32
Thus, the required cost of mail of the object of 35 pounds is $33.32.

2. What is the slope of the line through the points (-6, 3) and (-7,-4)?
a. 3/1
b. 1/7
c. 1/3
d. 7/1
The required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.
Given that,
To determine the slope of the line through the points (-6, 3) and (-7,-4).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the line is given by,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute the point in the above equation,
m = 3 + 4/ -6 + 7
m =7 / 1
m = 7
Thus, the required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.

Step-by-step explanation:
16x = 22+5x
1) 16x-5x = 22 + 5x - 5x =
11x = 22

Answer:
x=2
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
16*x-(22+5*x)=0
Pull out like factors :
11x - 22 = 11 • (x - 2)

Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
Given:
Two equations are
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
To find:
The reason for same solutions to the proportions.
Solution:
First equation is
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
On cross multiplication, we get
[tex]50\times 20=10\times x[/tex]
[tex]1000=10x[/tex]
Divide both sides by 10.
[tex]\dfrac{1000}{10}=x[/tex]
[tex]100=x[/tex]
The second equation is
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
On cross multiplication, we get
[tex]10\times x=50\times 20[/tex]
[tex]10x=1000[/tex]
Divide both sides by 10.
[tex]x=\dfrac{1000}{10}[/tex]
[tex]x=100[/tex]
Solutions to the proportions are same because both result in the equation 10 x = 1,000, which simplifies to x = 100.

Sonya is a waitress. She earns $200 per week plus a 15% tip on the cost of each meal she serves. What must be the total cost of the meals she serves in order for her to earn at least $425 each week?
help me please
Answer:
Sonya would need to serve 1500 meals
Step-by-step explanation:
425=15%(x)+200 or 425=.15(x)+200
solve for x
425=.15x+200 distribute
subtract 200 from both sides
225=.15x
divide both sides by .15 to isolate x
1500=x or x=1500

It cost $75 to rent a limo, plus $20 per hr. Write an equation to represent the total cost,c, of renting the limo for T hours.
We must create the equation from the information. Well, we know that there is a 75 dollar fee right off the top, and there is the word "plus" in the information meaning there will be adding.
1. Add the given cost plus the addition sign.
75 + ___ = ?
Now, we must find out what fills in "__." It says that it costs $20 per hour to rent the limo. However, it doesnt tell you how many hours it is being rented for, however it does say that the amount of hours is represented by T. So, fill in that information.
2. Fill in the second number.
75 + 20T = ?
Since there isn't a number to finish the second number to the equation, we know that there isn't going to be a completed answer. So, fill in the final cost with "c" as explained in the equation.
3. Write the answer.
75 + 20T = c
So, the equation to this problem is:
75 + 20T = c
Which is how to find out how much the limo costs to rent it.

Answer: 127 degrees
Step-by-step explanation:
I hope this helps
E F
H G
I had to write it out the parallelogram so I could have a better visual.
F and G are consecutive angles in a parallelogram (not on opposite sides).
This means they add to be 180 degrees.
F+G=180
(3x-10)+(5x+22)=180
(3x+5x)+(-10+22)=180
8x +12=180
Subtract 12 on both sides:
8x =180-12
Simplify:
8x =168
Divide both sides by 8:
x =168/8
x =21
If x=21 and want the measurement of angle G, then
(5x+22)=(5*21+22)=127.
So angle G has measurement 127 degrees.
The the measure of angle G will be 127°. Then the correct option is D.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
In parallelogram, the sum of the two adjacent angle is 180 degrees.
In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°.
The angle F and angle G are the adjacent angle.
The sum of angle F and angle G is 180°.
∠F + ∠G = 180°
3x - 10 + 5x + 22 = 180
8x = 168
x = 21
Then the the measure of angle G will be
∠G = (5x + 22)°
∠G = (5 × 21 + 22)°
∠G = (105 + 22)°
∠G = 127°
The the measure of angle G will be 127°.
Then the correct option is D.
