If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula. $m= \frac{4-(-3)}{4-(-1)}= \frac{7}{5}$ . So our slope is 7/5. The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is $y= \frac{7}{5}x- \frac{3}{2}$ , choice D from above.

The functions f and g are defined as follows f(x)=5x+3/6x+7 and g(x)= square root sign x^2-4x

telo118 [61]

<span>f(x)=5x+3/6x+7

This means that f(6/x) = [</span>5(6/x)+3] / [6(6/x)+7] = [ 30/x +3 ] / [36/x +7]

If we assume x≠0 , f(6/x) = [30 +3x]/ [36 + 7x]

g(x)=√<span> [ x^2-4x ]

g(x-4) = √ [ (x-4)^2-4(x-4) ] = √ [ x² -8x +16 -4x +16 ] = √ [ x^2-12x +32]

Your monthly living expenses are $1500 on an income of $1,650 per month. Your goal is to have an emergency fund of 4 times your

Aneli [31]

For the answer to the question above, your end goal is to have $6,000 total in 12 months. since you have $2400 already you can subtract that from 6,000 leaving you with $3600 over the course of 12 months. since you already put $150 in a month over the course of 12 months you would have $1800 which is only half of the goal of $3600. in order for you to put in $3600, you would have to put an additional 150 in your savings along with your regular 150 making Letter B the answer.

Answer:

-31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

$c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}$

Your graphing calculator can probably help with this.

How do u do percentage

lbvjy [14]

Answer:

Step-by-step explanation:

Ill try to break this down, simply:

When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.

Lets say we have 2 out of 10 apples and we need to convert this to a percentage

First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:

So if we put the part that we have over the whole thing we get:

$\frac{2}{10}$

So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!

So we have 2 and if we move the decimal back one place we get .2 or 0.2

Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100

So:

0.2 x 100 = 20%

All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:

0.2 --> 2. --> 20.

Which gives us again 20%

Which of the following expressions are equivalent to -5/-7×-11/-6

USPshnik [31]

Answer:

Step-by-step explanation:

-5/-7×-11/-6

= (-5 * -11) / (-7*-6)

= 55 / 42.

A. = - (6/-11) = 6/11

-5/7 * 6/11 = -30/77.

B. - (-11/7) = 11/7

5/6 * 11/7

= 55/42.
