If you received $175.84 on $314 invested at a rate of 7%, for how long did you invest the principle?

Harrizon [31]

Answer:

8 years

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest

P = principal

r = rate (as decimal)

t = time

In your case,

I = $175.84

P = $314

r = 0.07, then

$175.84=314\cdot 0.07\cdot t\\ \\175.84=21.98t\\ \\t=\dfrac{175.84}{21.98}\\ \\t=8$

What is the slope intercept from for 16x+9y=40

Doss [256]

Answer:

$y = (- \frac{16}{9})x + \frac{40}{9}$ is the slope intercept form for 16x+9y=40

Step-by-step explanation:

Here, the given equation is 16 x + 9 y = 40

Now, the slope intercept form of an equation is y = mx + c,

here m = slope of the equation, b = y - intercept

So, now 16x + 9y = 40 on simplification gives

9y = 40 - 16x

or $y = \frac{40 - 16x}{9} = \frac{40}{9} - \frac{16x}{9}$

or, $y = (- \frac{16}{9})x + \frac{40}{9}$ is the slope intercept form of the given equation.

Here, m = (-16/9) and y- intercept = 40/9

Zanzabum

Answer:

5.9+z=−9

Step 1: Simplify both sides of the equation.

z+5.9=−9

Step 2: Subtract 5.9 from both sides.

z+5.9−5.9=−9−5.9

z=−14.9

Answer:

z=−14.9
