Mathematics
1 answer:
Vaselesa [24]3 years ago

The solution is x = -61/8 and y = -1/2.

<u>Step-by-step explanation</u>:

The given equations are -4x + 3y = 29 and 2y + 5 = 4

   <u>Step 1</u> : There is no x term in the second equation.

   <u>Step 2</u> : Solve for y, 2y = 4 -5

                                      y = -1/2

   <u>Step 3</u> : Substitute y = -1/2 in first equation and solve for x.

   <u>Step 4</u> : -4x + 3(-1/2) = 29

                 -4x -(3/2) = 29

                 -8x -3 = 29\times2

                 -8x = 58 + 3

                  x = -61/8

Find the sum of the following infinite sequence: 8, 2, .5, …
lubasha [3.4K]
Answer:
10.67

Explanation:
The given series is a geometric series:
8 , 2 , 0.5 , ...... etc

The general formula of the geometric sequence is:
a1 , a1*r , a1*r² , ......

Comparing the general form with the given, we would find that:
a1 = 8
a1 * r = 2
Therefore:
8*r = 2
r = 2/8 = 0.25

We can double check using another term as follows:
a1 = 8
a1*r² = 0.5
8r² = 0.5
r² = 0.5/8 = 0.0625
r = √0.0625 = 0.25

Now, we will get the sum of the sequence as follows:
S = \frac{a1}{1 - r} = \frac{8}{1 - 0.25} = 32/3 = 10.67

Hope this helps :)

Rose bought a new hat when she was in vacation. If the hat cost $975 and the sales tax was 6%, how much did rose pay for the hat
Rufina [12.5K]

Hi!


To solve this, set up a proportion and cross multiply.


\frac{x}{975} \frac{6}{100}


975 x 6 = 5850

5850/100 = 58.5


58.5 + 975 = 1033.5


The answer is $1033.5


Hope this helps! :)
