-9x = 5 - 2y. 15x = -11 + 2y HELP ​

Mathematics
1 answer:
I am Lyosha [343]3 years ago

Answer:

(-1, -2)

Step-by-step explanation:

-9x= 5 - 2y

15x = -11 + 2y => 2y = -11 - 15x

Plug the value for 2y into the first equation.

-9x = 5 - 15x - 11. Solve for x.

-9x = -6 - 15x.

-9x + 15x = -6.

6x = -6.

x = -1.

Now that we found x, we will solve for y.

2y = -11 - 15(-1)

2y = -11 + 15

2y = -4

y = -2.

Thus, our solution set is (-1, -2).

Hope this helps!

PLEASE Help ....... Will mark brainliest
Andru [333]

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.

p = s + dgh

dgh = p - s

h = (p - s)/dg

Which formula represents h in terms of p, s, d, and g? Formula B is correct.

Answer:

E: L is perpendicular to a line with slope -\frac{3}{2}.

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of \frac{2}{3} is \frac{3}{2} (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of \frac{2}{3} is -\frac{3}{2}. This represents the slope of a line that is perpendicular.
