Mathematics
1 answer:
Nimfa-mama [501]3 years ago
7 0

Answer:

Step-by-step explanation:

total price was reduced by $ 7

let x = the total price........ x - 7

he bought 10.....and it cost him $ 130

10(x - 7) = 130

10x - 70 = 130

10x = 130 + 70

10x = 200

x = 200/10

x = 20 <====== original price

Write the first three terms in the following sequences. Identify them as arithmetic or geometric
vaieri [72.5K]

Answer:

A(1)=9

A(2)=4

A(3)=-1

Arithmetic sequence

Step-by-step explanation:

We are given that

A(n+1)=A(n)-5 \;for\;n\geq 1 A(1)=9

We have to find first three terms and identify the sequence is geometric or arithmetic.

Substitute n=1

Then, we get

A(2)=A(1)-5=9-5=4

For n=2

A(3)=A(2)-5=4-5=-1

For n=3

A(4)=-1-5=-6

d_1=A_2-A_1=4-9=-5

d_2=A_3-A_2=-1-4=-5

d_3=A_4-A_3=-6+1=-5

d_1=d_2=d_3=-5

When the difference of consecutive terms are constant then the sequence is arithmetic sequence.

Therefore, given sequence is arithmetic sequence.

Which is an equation of the line that passes through<br> the points (5, 2) and (10, -3)?
sashaice [31]

Answer:

y = -x + 7

Step-by-step explanation:

Hi there!

We are given the following points:
(5,2) and (10,-3)

We want to find the equation of the line that passes through these 2 points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).

First, let's find the slope of the line.

The slope can be calculated from 2 points using the equation \frac{y_2-y_1}{x_2-x_1}, where (x_1, y_1) and (x_2, y_2) are points

We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.

x_1=5\\y_1=2\\x_2=10\\y_2=-3

Now substitute these values into the formula to find the slope

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-3-2}{10-5}

Simplify

m=\frac{-5}{5}

Divide

m=-1

The slope of the line is -1

We can substitute this value as m in y=mx+b.

Here's the equation of our line so far:

y=-x+b

Now we need to find b

As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b

Taking (5,2) for example:

Substitute 5 as x and 2 as y

2=-5+b

Add 5 to both sides

7=b

Substitute 7 as b in the equation

y = -x + 7

Hope this helps!
