Answer:

The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct

Step-by-step explanation:

Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.

He decides to make a poster advertising a simple interest rate of 4.8%.

We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month

We know that, banks offer simple interest

In our problem, simple interest = $10, rate = 4.8%, time = 1 month

Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?

So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =

So, the statement is correct.

Hence, amount to be invested is $2500 and poster says correctly.

Answer:

1. $x=3$

2. $1$

3. $x=11$

Step-by-step explanation:

$1.\\\frac{x}{5}=\frac{12}{20}\\\\x=3\\\\\\2.\\-1\frac{3}{5}*(-\frac{5}{8})=\\\\-\frac{8}{5}*(-\frac{5}{8})=\\\\-(-\frac{40}{40})=\\\\-(-1)=\\\\1\\\\\\3.\\\frac{x}{14}=\frac{55}{70}\\\\x=11$

3x - 12 = 3x + 1<br> help please

Answer:

There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.

Write a linear equation in Slope-Intercept Form for a line that goes through the

Kitty [74]

Answer:

y = -2x -9

Step-by-step explanation:

<h2><u>in order to solve this question you have to do the following : </u></h2>

1. find the midpoint of the coordinates given

2. find the gradient of the line

3. make the equation

<h3><em><u>STEP : The midpoint </u></em></h3>

formula of the midpoint is

$\frac{x2 + x1}{2} , \frac{y2 + y1}{2}$

now place the values in the equation :

$\frac{-4 +-2}{2} , \frac{-5 + -1 }{2}$

midpoint = ( -3 , -3)

<h3><em><u>STEP 2 : The gradient </u></em></h3>

formula of finding the gradient

$\frac{y2-y1}{x2-x1}$

insert the values in the equation:

$\frac{-5-(-1)}{-2-(-4)}$

= $\frac{-4}{2} = -2$

gradient = -2

<h3><em><u>STEP 3: Form the equation </u></em></h3>

use the formula of the equation :

$(Y - y1) = m( X - x1)$

now make use of the gradient(m) and the midpoints and insert into the equation

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

hence

y+3 = -2 (x +3)

y= -2x -6 -3

<h3><u /></h3><h3><u>y = -2x -9 </u></h3>
