Answers

Answer 1

Answer:

1. x=−2y+3

2. [tex]\frac{5}{2} y - 5[/tex]

Step-by-step explanation:

Answer 2

Step-by-step explanation:

2x+4y = 6

-2x +5y = 10

9y = 16

y = 16/9

2x+ 4(16/9) = 6

2x +64/9 = 54/9

2x = -10/9

Jackson deposits $4,200 in a savings account that pays 3.5% annual interest.What is the total value of the account after 10 years

Answers

Answer:

5924, 51

Step-by-step explanation:

X = 4200(1.035)^10

And put it in a calculator

The total value of the account after 10 years is $5,924.52.

Given that,

The deposited amount is $4,200.The rate of interest is 3.5%.And, the time period is 10 years.

Based on the above information, the calculation is as follows:

[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]

= $5,924.52

Therefore we can conclude that the total value of the account after 10 years is $5,924.52.

hello everyone ,
i am having some problems solving this question in maths
Arrange 13.25 kg, 14560 g, 13.6 kg, 12000 g in descending order ,
Write the following decimals as fractions. Reduce the fractions to lowest
form.
a) 3.6 b) 12.5
i hope u also consider explaining
thank you all .

Answers

Answer:

Descending order:

14560g

13.6kg

13.25kg

12000g

a.) [tex]\frac{18}{5}[/tex]

b.) [tex]\frac{25}{2}[/tex]

Step-by-step explanation:

To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.

If we were to put everything into g:

14560g

13600g

13250g

12000g

See how they are still in the correct order?

If we were to put everything into kg:

14.56kg

13.6kg

13.25kg

12kg

Still in descending order!

___________________

Now to find out how to put the decimals into fractions:

Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)

Following this we get:

36

125

Now divide by the same factor (10), we can't change the value of the number, just the way they look!

[tex]\frac{36}{100}[/tex]

[tex]\frac{125}{10}[/tex]

All that's left is it reduce!

[tex]\frac{18}{5}[/tex]

[tex]\frac{25}{2}[/tex]

And as you can see, we are back to the number I had put in the solution!

A bank offers 2% simple interest per year. A woman opens an account with deposit of 900 pounds. She closes the account 2 years later. How much will she withdraw.

Answers

simple interest formulae = PRT/100

where

p stands for percentage (2%)

r stands for rate ( 900)

t stands for time (2 years )

2×900×2/100

=3600/100

=36

Deposit interest

Level : SHS Keyword : deposit interest, simple interest

Deposit Interest in 2 years

= D × i × T/365 days

= 900 pounds × 2% × (365 × 2 years)/365 days

= 900 pounds × 0.02 × 730 days/465 days

= 900 pounds × 0.02 × 2

= 36 pounds

Her Deposit in 2 years

= 900 pounds + 36 pounds

= 936 pounds

So, her deposit if she will withdraw is 936 pounds

Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, -1). Use the box provided to submit all of your calculations and final answers.

Answers

Answer:

y + 1 = [tex]\frac{1}{2}[/tex] (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 1 ) and (x₂, y₂ ) = (2, 1 )

m = [tex]\frac{1-(-1)}{2-(-2)}[/tex] = [tex]\frac{1+1}{2+2}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex] and (x₁, y₁ ) = (- 2, - 1 ) , then

y - (- 1) = [tex]\frac{1}{2}[/tex](x - (- 2) ) , that is

y + 1 = [tex]\frac{1}{2}[/tex] (x + 2)
