Which is the equation of a line that has a slope of -2/3 and passes through point (-3,-1)?

Fantom [35]

Answer:

Step-by-step explanation:

You have to use Point Slope Form:

y - Y1 = m (x - X1)
m is the slope
Y1 & X1 is a point on the line
The form allows you to identify the slope & the point on the line

About Problem:

Since -2/3 is the slope, it represents m in y - Y1 = m (x - X1) form.

-3 represents X1 in y - Y1 = m (x - X1) form

-1 represents Y1 in y - Y1 = m (x - X1) form

y - Y1 = m (x - X1)

y - -1 = -2/3 (x - -3) ---- This is in Point Slope Form

If you want to solve it, & put it in Slope Intercept form, it would look like this:

y = mx + b

y = -2/3 - 2 --- This is in Slope intercept Form.... I might've solved it wrong... I'm not sure...

Really really sorry if I'm incorrect...

after 45 sec camdens bathtub fills with 3 inches of water how many seconds will it take to fill tub with 20 inches of water?

Marizza181 [45]

3/45 = 20/x...3 in to 45 seconds = 20 in to x seconds
cross multiply
(3)(x) = (45)(20)
3x = 900
x = 900/3
x = 300...300 seconds (or 5 minutes)to fill the tub with 20 inches

D)) The ratio of the monthly income and expenditure of Sunayana is 5 : 3. If she

Gnom [1K]

Answer:

Sunayana's income is ₹25000 and expenditures are ₹15000.

Step-by-step explanation:

Let i denote the monthly income and e denote the expenditures.

We know that the ratio of the monthly income to expenditure is 5:3. So, we can write the following proportion:

$\frac{i}{e}=\frac{5}{3}$

Let's multiply both sides by e. This yields:

$i=\frac{5}{3}e$

We know that when the income is <em>increased</em> by 5000 and the expenditures are <em>decreased </em>by 3000, the new ratio is 5:2. So, we can write the following proportion:

$\frac{i+5000}{e-3000}=\frac{5}{2}$
