**Answer:**

The first term will be 38.375

**Step-by-step explanation:**

aₙ = a₁ + (n - 1) * d

a₂₀ = -40

a₂₈ = -73

**-40 = a₁ + 19d**

**-73 = a₁ + 27d**

*When we have two similar equations with two unknowns, we can subtract them to get an answer.*

** -40 = a₁ + 19d --> -40 = a₁ + 19d**

**-(-73 = a₁ + 27d) --> 73 = -a₁ - 27d**

**-------------------------------------------------**

**33 = -8d**

*Solve for ***d*** by dividing by ***-8**

**d = -4.125**

*Now plug ***d*** into one of the original equations to solve for ***a₁**

**-40 = a₁ + 19(-4.125)**

**-40 = a₁ - 78.375**

**a₁ = 38.375**

HELP PLS Write the equation of the line in fully simplified slope-intercept form.

The **equation **of the **line **that passes through the x-intercept ( -2,0 ) and y-intercept ( 0,1 ) is y = (1/2)x + 1.

The formula for **equation **of **line **is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

From the graph, the x and y-intercept are; ( -2,0) and (0,1 )

Point 1 ( -2,0 )

x₁ = -2y₁ = 0Point 2( 0,1 )

x₂ = 0y₂ = 1First, we determine the slope of the line.

Slope m = y₂ - y₁ / x₂ - x₁

Slope m = 1 - 0 / 0 - (-2)

Slope m = 1 / 0 +2

Slope m = 1/2

Next, determine the y-intercept b by substituting the slope and a point into the equation of line formula.

y = mx + b

0 = (1/2)(-2) + b

0 = -2/2 + b

0 = -1 + b

b = 1

Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the **equation **of the **line**.

y = mx + b

y = (1/2)x + 1

Therefore, the **equation **of the **line **is y = (1/2)x + 1.

(10x - 3) ÷ 5 - (1 ÷ 4) = 55 ÷ 4

(7x ÷ 5) - (1 ÷ 4) = 55 ÷ 4

Add (1 ÷ 4) on both sides,

A piggy bank contains $2.65 in nickles and dimes. if the number of nickles is 7 less than three times the number of dimes. how many of each are there

In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes. Then There are 29 **nickels **and 12 dimes in the piggy bank.

We need to find the number of **nickels **and dimes if the number of nickels is 7 less than three times the number of dimes.

Let x be the number of **nickels **and y be the number of dimes.

We know that, 1 dollar = 20 nickels

and 1 dollar = 10 dimes

So, we get an equation

0.05x + 0.1y = 2.65 ...........(1)

Also the number of nickels is 7 less than three times the number of dimes.

x = 3y - 7 .................(2)

Substitute above value of x in **equation **(1)

0.05(3y - 7) + (0.1)y = 2.65

0.15y - 0.35 + 0.1y = 2.65

0.25y = 2.65 + 0.35

0.25 y = 3

y = 12

Substitute above value of y in **equation **(2)

x = 3(12) - 7

x = 29

Therefore, there are 29 **nickels **and 12 dimes in the piggy bank.

day that he's on vacation plus $650 for miscellaneous activities. He

has $2750 dollars in his savings account. How many days can he go

on vacation?

The **number** of **days** Henry can go on vacation is 7 days.

Given that, Henry knows it will cost $300 per day that he's on vacation plus $650 for miscellaneous activities.

What is an equation?In mathematics, an **equation** is a formula that expresses the **equality** of **two expressions**, by connecting them with the equals sign =.

Let the number of days be x.

Henry has $2750 dollars in his savings account.

So equation is 300x+650=2750

The obtained **equation** can be solved as follow

300x=2750-650

⇒ 300x = 2100

⇒ x = 2100/300

⇒ x = 7

The function f(x) = 210-60x represents a second trip, where f(x) is the number of miles

the car is from its destination after x hours. Which trip takes less time? Explain.

**Answer:**

the trip represented by f(x) takes less time

**Step-by-step explanation:**

Given a **table of time and distance to go**, and a function **f(x) = 210-60x** representing the same for a different trip, you want to know **which trip takes less time**.

The table has values ...

(time in hours, remaining distance in miles) = (1, 150), (2, 100), (3, 50)

This shows you the remaining distance decreases by 50 miles for every hour added to the travel time. That means the remaining 50 miles will be reduced to zero after 4 hours.

The trip represented by the table takes **4 hours**.

The function f(x) = 210-60x will have a value of zero when ...

0 = 210 -60x

0 = 3.5 -x . . . . . . divide by 60

x = 3.5 . . . . . . . . add x

The trip represented by the function f(x) takes **3.5 hours**.

**The second trip takes less time**.

The length of the rectangle is 5 more than twice the width. If the perimeter is 10 times that of the width, what is the width, length, and perimeter of the rectangle?

**Width** of the rectangle is 2.5,** Length** is 10 and **perimeter** is 25

Given

Length of rectangle is **5 greater than double of width**

let us say width = w

According to the question length L = 5 + 2w

Perimeter is **10 times the width**

P= 10w

we know that **perimeter **of a rectangle is** 2(L+W)**

Substituting the values in the **formula** we get

10w = 2(5+2w + w)

10w = 10 + 6w

w= 2.5

From this length L = 5+2(2.5)

L = 10

Perimeter P = 10W

P= 10(2.5)

P= 25

Hence the **length** is 10, **width **is 2.5 and **perimeter** is 25
