6 would be $240.

Take 6,000 and multiply it by 4% which means you need to convert 4% to a decimal.
4% as a decimal is 0.04. 6,000 x 0.04 equals 240.

hope this is correct and sorry but I do not understand how to do 7.

What is 5^-3?

1/15

You take out the negative and do the regular equation but turn it into the fraction with one as the numerator and the solution of the exponent as the denominator.

Changing the equation into slope form: $y = mx + c$ , where $m$ is the slope [gradient] and $c$ is the y-intercept.

$2x+3y=1470$
$3y = -2x+1470$
$y= - \frac{2}{3}x+ \frac{1470}{3}$
$y=- \frac{2}{3}x+490$

The gradient is $- \frac{2}{3}$ and y-intercept is at $y=490$

Graphing $y=- \frac{2}{3}x+490$ using slope-intercept method:
a) The slope is a negative slope. The line will go 'down hill'
b) The line must pass the point (0, 490)
c) The line will intercept the x-axis at y = 0
   $0 = - \frac{2}{3}x+490$
   $\frac{2}{3}x = 490$
   $2x = 1470$
   $x = \frac{1470}{2}$
   $x = 735$
So, x-intercept is at (735, 0)

The graph of this function is shown below. The intercepts are labelled at:
y = 490
x = 735

Next month's profit equation

$2x+3y=1593$

Rewriting this into slope-equation form

$3y = -2x+1593$
$y=- \frac{2}{3}+ \frac{1593}{3}$
$y= - \frac{2}{3}+531$

The gradient, $m$ , equals to $- \frac{2}{3}$
The y-intercept, $c$ , equals to 531

The equation still has the same gradient with last month's profit equation but different y-intercept.

A linear graph show points of (0, 300) and (450, 0)

We work out the slope:
$\frac{300-0}{0-450} = \frac{300}{-450}=- \frac{20}{30} =- \frac{2}{3}$

Y-intercept at x = 0, so it's at y = 300

Equation $y = - \frac{2}{3}+300$

Solve 3x+10> or equal 4

insens350 [35]

If you try to solve for x it is not able to be solved because the variable must be located in between the inequality signs, but if i simplified your problem then it would be: x is greater than or equal to -2.

I really hoped this helped. Good luck.

A room is 8.5 m long,6.5 m broad and 3.4 m high. it has two doors, each measuring (2 m 1m).find the cost of painting its four wa

levacccp [35]

Find the surface area of the 4 walls by doing
2(8.5x3.4) + 2(6.5x3.4)
Then subtract the area of the 2 doors , which is 4
So the total painted surface will come out to be 98m
Multiply 98 by the cost, £160 to get a total cost of £15680 to paint the room
