Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3

Answer:
The answer is 61.
Step-by-step explanation:
You have to substitute x = -8 into the function :
![f(x) = {x}^{2} - 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%203)
![let \: x = - 8](https://tex.z-dn.net/?f=let%20%5C%3A%20x%20%3D%20%20-%208)
![f( - 8) = {( - 8)}^{2} - 3](https://tex.z-dn.net/?f=f%28%20-%208%29%20%3D%20%20%7B%28%20-%208%29%7D%5E%7B2%7D%20%20-%203)
![f( - 8) = 64 - 3](https://tex.z-dn.net/?f=f%28%20-%208%29%20%3D%2064%20-%203)
![f( - 8) = 61](https://tex.z-dn.net/?f=f%28%20-%208%29%20%3D%2061)
11 divided by 5 is 2.2 and you multiply that by 2 1/4 which is 2.25 in decimal form. The answer is 4.95
Answer:
108 ounces
Step-by-step explanation:
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
Equation 1: x + y = 180
Equation2: y = 180 - x
.60x+.85y=.75(180)
.60x+.85y=135
Multiply both sides of the equation by 100 to remove the decimal points.
60x+85y=3500
60x+85(180 - x)=13500
60x+15300-85x=13500
-25x=-1800
x=72ounces
y=180-72
y=108 ounces
