Slope intercept form: y = mx + b

Solve for y:

3x - 9y = 36

~Subtract 3x to both sides

3x - 3x - 9y = 36 - 3x

~Simplify

-9y = 36 - 3x

~Divide -9 to both sides

-9y/-9 = 36/-9 - 3x/-9

~Simplify

y = -4 + 1/3x

Therefore, the answer is y = 1/3x - 4

Best of Luck!

Answer:

y = 1/3x -4

Step-by-step explanation:

Solve for y

3x-9y = 36

Subtract 3x

3x -3x-9y = -3x +36

-9y = -3x +36

Divide by -9

-9y/-9 = -3x/-9 + 36/-9

y = 1/3x -4

This is in slope intercept form ( y = mx+b) where m is the slope and b is the y intercept

Suppose $2000 is invested at 9% interest compounded continuously. How long will it take for the investment to grow to $10,000? U

Lady bird [3.3K]

Answer:

Step-by-step explanation:

sing the equation > A = Pe^rt

20000 = 10000e^0.1t > 10% = 0.1

2 = e^0.1t

log 2 = log e^0.1t > log to the base e

log 2 = 0.1t * 1 log e to the base e =1

0.6931 = 0.1t

t = 6.931

= 7 years

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much doe

babymother [125]

Call the weights of the two dogs $t$ and $r$ .

We know that Tripp weights 35lbs more than Rico, or:
$t=r+35$

We also know that the total weight of both dogs is 49lbs.:
$t+r=49$

Now, by substitution:
$(r+35)+r=49$
$2r+35=49$
$2r+35-35=49-35$
$2r=14$
$r=\frac{14}{2}$
$r=7$
Rico weighs 7lbs.

Then:
$t=r+35$
$t=7+35$
$t=42$
Tripp weighs 42lbs.

To check our work:
$t+r=49$
$42+7=49$
$49=49$ CHECK!

Please help me with the question

ivanzaharov [21]

Answer:

Step-by-step explanation:

Since it's at the same time of the day, the ratio between the height of the person and the shadow they cast will stay the same. So the man's height to shadow ratio is 6:8 = 3:4. The son's height to shadow ratio would be the same so x:4 = 3:4 therefore his height is 3 feet.
