What is a detailed example of simple interest?

Mathematics

Answer:

Car loans, amortized monthly, and retailer installment loans, also calculated monthly, are examples of simple interest; as the loan balance dips with each monthly payment, so does the interest. Certificates of deposit (CDs) pay a specific amount in interest on a set date, representing simple interest

Find the equation of this line. y= [?]x+[?]

DochEvi [55]

Answer:

$y=3x-4$

Step-by-step explanation:

Hi there!

Slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x=0)

1) Determine the slope (m)

$m=\displaystyle\frac{y_2-y_1}{x_2-x_1}$ where two points that fall on the line are $(x_1,y_1)$ and $(x_2,y_2)$

On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:

$m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3$

Therefore, the slope of the line is 3. Plug this into $y=mx+b$ :

$y=3x+b$

2) Determine the y-intercept (b)

$y=3x+b$

Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into $y=3x+b$ :

$y=3x+(-4)\\y=3x-4$

I hope this helps!

Mr.Thompson is on a diet. He currently weighs 250 pounds. He loses 3 pounds per month. Write an equation that models Mr.thompson

jekas [21]

250-3m

m represents months

Not an equation but an expression since I don’t know the number of months he was on the diet.

Y+4=2(x-1) what would it be from point-slope form to slope-intercept form

Lilit [14]

Answer:

y=2x-6

Step-by-step explanation:

y+4=2(x-1)

Subtract 4 to both sides of the equation:

y+4-4=2(x-1)-4

y=2(x-1)-4

Distribute the 2:

y=2x-2-4

y=2x-6

Where 2 is the slope and -6 is the y - intercept.

Twenty-seven minus 1.5 of a number (x) is not more than 36. What is the number?

alexandr1967 [171]

Translate this into symbols: 27 - 1.5x is equal to or less than 36. Find x.

Add 1.5x to both sides, so as to make the coefficient of x positive:

27 = 36 + 1.5x, or -9 = 1.5x, or x = -6 but also
x > -6

Check: let x = -6. Is the given equation then true?

27 = 36 + 1.5(-6) => -9 = -9? Yes.

Check: let x > -6. Is Twenty-seven minus 1.5 of a number (x) not more than 36? 27 - 1.5(0) not more than 36? True.

Thus, x is equal to or greater than -6.
