Kx-bf=fy/m solve for y

So you need to isolate y:
First you multiply m on both sides:
m(Kx - bf) = fy
Then, you divide f on both sides:
\frac{(m(Kx-bf))}{f} = y

Multiply both sides by (m) and you get (mkx-mbf=fy)

Then divide both sides by (f) and you get ((mkx-mbf)/(f)) = y

If f(x)=5x-2 and g(x)=2x+1, find (f+g)(x)<br> A.7x-3 <br> B.3x-1 <br> C.7x-1 <br> D.4x-3
Gwar [14]

Answer:

(f+g)(x) = 7x -1  (Answer C)

Step-by-step explanation:

Rewrite these two functions, one above the other, for ease in adding:

f(x) = 5x - 2

+g(x) =2x + 1

------------------

(f+g)(x) = 7x -1

The student council set a goal of raising at least $500 in flower sales. So far it has raised $415. Write an inequality to show
sergij07 [2.7K]
$500 < or = $415 + d

(subtract the 415 from both sides)

A) Rate (R)<br>24/5<br>Time = 1 month<br>Interest = Rs. 39.96​
yKpoI14uk [10]

Answer:  P = $ 1,998.01

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 24%/100 = 0.24 per year,

putting time into years for simplicity,

1 months ÷ 12 months/year = 0.083333 years,

then, solving our equation

P = 39.96 / ( 0.24 × 0.083333 ) = 1998.007992032

P = $ 1,998.01

The principal required to

accumulate interest of $ 39.96

on a rate of 24% per year for 0.083333 years (1 months) is $ 1,998.01.

Answer each question using ratios.
Gnom [1K]

Answer:

B) 42:28

Step-by-step explanation:

First, let's get 12:18 simplified to make it easier to compare:

12:18 -> 4:6 - > <u>2:3</u>

Now let's check it against all the options:

A) 20:30 -> 2:3 and 2:3 = 2:3

Not our answer as it is congruent (equal too, the same as, etc)

B) We can see that the first number is larger than the second number, so without doing too much math we can see this is our answer!

42:28

(it simplifes to 6:4 -> 3:2)

(we do not have to do the following as we already have an answer, but here is the math)

C) 4:6

4:6 ->

2:3 = 2:3

D) 2:3

2:3 = 2:3
