Convert the equation to slope- intercept and standard form. y-4=5 + 1/2x

Vitek1552 [10]

Answer:

note :

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

Step-by-step explanation:

in this exercice : y - 4 = 5 +(1/2)x

y - 4 = 0.5 ( x - 5/0.5)

y - 4 = 0.5( x - 10).....

note : the standard forme is : y = ax +b

in this exercice : y = (1/2)x+9

galben [10]

Answer:

See below

Bold parts are important parts. They are the equations.

Marina had RM24,500 to invest.

If the amount of money in the 4% account was four times the amount of money in the 5.5% account.

" At the end of the year, she had made RM1,300 in interest. The annual yield on each of the three accounts was 4%, 5.5%, and 6%."

"If the amount of money in the 4% account was four times the amount of money in the 5.5% account,"

a = 4b

Down is the equations.

let a = amt in the 4% acct

let b = amt in the 5.5% acct

let c = amt in the 6%

"Marina had RM 24,500 to invest."

a + b + c = 24500

Replace a with 4b in both equations, simplify

b = $2000 in the 5.5% investment

a = $8000 in the 4% acct

Hope this helps.

A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if ther

prisoha [69]

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

$y=a\cdot (1+r)^x$ , where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

$75\%=\frac{75}{100}=0.75$

Upon substituting initial value $a=4$ and $x=12$ in above formula, we will get:

$y=4\cdot (1+0.75)^{12}$

$y=4\cdot (1.75)^{12}$

$y=4\cdot 825.0050068497657776$

$y=3300.020027$

$y\approx 3300$

Therefore, there will be approximately 3300 cells at the end of 12 hours.

An mp3 player is on sale for 25% off. The original price is $52.60. What is the sale price?

Paha777 [63]

First, you need to find 25% of 52.60

Convert 25% to decimal:
25% = .25

Find 25% by multiplying its decimal equivalent by the sales price.

.25 x 52.60 = 13.15

Next, subtract that amount from 52.60 to find the new sale price.

52.60 - 13.15 = 39.45

The final price is $39.45
