Solution as ordered pair is:

(5, $\frac{41}{2}$ )

Step-by-step explanation:

Solving the system of equations:

$3x+2y=56\,\,\,(1)\\9x-2y=4\,\,\,(2)$

Adding equation(1) and equation(2)

$3x+2y=56\\9x-2y=4\\--------\\12x=60\\x=\frac{60}{12}\\x=5$

Putting value of x i.e x=5 in equation(1)

$3x+2y=56\\3(5)+2y=56\\ 15+2y=56\\2y=56-15\\2y=41\\y=\frac{41}{2}\\y=\frac{41}{2}$

So, value of x=5 and y= $\frac{41}{2}$

Solution as ordered pair is:

(5, $\frac{41}{2}$ )

Which point is in the solution set of the given system of inequalities 3x+y>-3,x+2y<4

Dima020 [189]

Step 1. Solve both inequalities for $y$ :
$3x+y\ \textgreater \ -3$
$y\ \textgreater \ -3x-3$

$x+2y\ \textless \ 4$
$2y\ \textless \ -x+4$
$y\ \textless \ - \frac{1}{2} x+2$

Step 2. To check a point in the solution of the given system of inequalities, look for the intercepts of the lines $-3x-3$ and $- \frac{1}{2} x+2$ :

$y=-3x-3$ (1)
$y=- \frac{1}{2} x+2$ (2)

Replace (1) in (2):
$-3x-3=- \frac{1}{2} x+2$
Solve for $x$ :
$\frac{5}{2} x=-5$
$x=-2$ (3)

Replace (3) in (1):
$y=-3x-3$
$y=-3(-2)-3$
$y=6-3$
$y=3$

We can conclude that the point (-2,3) is in the solution of the system if inequalities; also any point inside the dark shaded area of the graph of the system of inequalities is also a solution of the system.

Jamie opened a savings account with $1000. Each month, she will add $35 to the account. Let y represent the amount of money in t

ra1l [238]

Answer:

The answer is c: y = 35x + 1000

Step-by-step explanation:

Jamie starts off with 1000 which means that no matter how much more money she adds to the account she still has to add the 100 she already has. Then she is adding $35 per month so it would be positive 35 so the correct equation is

35x +1000

An object of mass weighing 5.24 kilograms is raised to a height of 1.63 meters. What is the potential energy of the object at th

Trava [24]

Find force,
9.8 m/s2 x 5.24 kg = 51.352 N 

Find work,
51.352 N x 1.63 m= 83.70 N*m

Example:
To solve this given word problem we can first identify the given and the apt formula to use in this phenomenon: Given: Force = 4, 500 N = 4, 500 kg-m/s^2 Acceleration = 5 m/s^2 
Formula: f=ma 
Derivation: m = f/a 
Solution: 
1. M = f/a 
2. M = 4,500 kg-m/s^2 / 5 m/s^2 
3. M = 900 kg 

Hence, the object’s mass is 900 kg.
