What is the slope of the line? (Slope from equation)
7x+2y=5
thanks.

Answers

This is the standard form of the equation. You have to make it into slope-intercept form to find the slope, hence the name.

7x+2y=5

7x+2y=5.
-7x. -7x. (You need to have y=)

2y=-7x+5.
/2. /2. (Divide by 2 to get only 1 y)


y=-7/2x+2.5. (Final Answer)



The slope is -7/2.

Answer:

The slope is -7/2.

Step-by-step explanation:

Convert to slope-intercept form (y = mx + b  where m = the slope)

7x + 2y = 5

2y = -7x + 5

Divide both sides by 2:-

y = (-7/2)x + 5/2

so slope m = -7/2

Jeremiah currently has an account balance of $1,624.35. His initial deposit on the account was $975 and it earned 3.7% simple interest. How long has Jeremiah held the account?

Answers

Answer:

Jeremiah has had the account for 18 years.

Step-by-step explanation:

Simple interest is the interest that is produced by investing or lending initial capital over a period of time. This interest rate does not accumulate at the initial capital, so the interest generated or paid in all periods is the same, while the interest rate and term do not vary.

The simple interest rate is usually expressed as a percentage, which must be expressed in decimal form in order to use its value in the equation shown below. For that, you must divide the percentage value by 100.

The amount of interest paid or charged depends on three important amounts: Capital, interest rate and time. This is expressed by the equation:

I = C * i * t

Where:

  • I: interest earned.
  • C: initial capital.
  • i: interest rate, which as mentioned, must be a decimal number.
  • t: period of time, expressed in years.

In this case:

  • I = $1624.35-$975 = $649.35 that is, the amount of interest earned during t years.
  • C=$975
  • i = 3.7%, which expressed in decimal form is 0.037 (3.7% / 100%)
  • t: is the time you want to calculate in which Jeremiah obtains a gain of $649.35.

Replacing in the equation, you get:

649.35=975*0.037*t

Isolating the value of t, you get:

t=18

So, Jeremiah has had the account for 18 years

$1624.35 - $975 = $649.35 
$649.35 = $975 * 0.037t
$649.35 = 36.075t
Now divide both sides by 36.075: $649.35/36.075 = 18
Answer: 18 years
