10% of $60 is $6. $6•3=$18. From there subtract $18 from $60... hope this helps :)

19x+15y=-6 changed into slope intercept form.

attashe74 [19]

Answer:

y = - $\frac{19}{15}$ x - $\frac{2}{5}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

19x + 15y = - 6 ( subtract 19x from both sides )

15y = - 19x - 6 ( divide all terms by 15 )

y = - $\frac{19}{15}$ x - $\frac{6}{15}$ , that is

y = - $\frac{19}{15}$ x - $\frac{2}{5}$ ← in slope- intercept form

A brick of mass 4 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 3 cm. The spring is t

Zielflug [23.3K]

Answer:

Step-by-step explanation:

In this system we have the force of the spring and the gravitational force. The equation that describes that is

$F_{s}+F{g}=ma\\k(y_0+y)-mg=ma$

where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have

$ky_0+ky-mg=ma\\mg+ky-mg=ky=ma\\\\ky=m\frac{d^2y}{dt^2}\\\\my''+ky=0$

the solution for this differential equation is (by using the characterisic polynomial)

$y(x)=Acos(kt)+Bsin(kt)\\k=\omega^2m$

hope this helps!!

15 POINTS !!!!

Natalija [7]

So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out.

So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

I hope this helps you! If it does, please rate as Brainliest :D

and y-intercept is-2

x-intercept is when you have a number comma 0 e.g 3,0. 2,0
