Answer:
C. D: -2≤x≤3 ; R: -1≤y≤4
Step-by-step explanation:
The domain is all the values on the x-axis (horizontally) and the range is all the values on the y-axis (vertically).
The x-axis values (domain) go from -2 to +3, which is -2≤x≤3.
The y-axis values (range) go from -1 to +4, which is -1≤y≤4.
Answer:
28
Step-by-step explanation:
Plug in the corresponding numbers to the corresponding variables. Note that:
m = 7
r = 8
t = 2
mr/t = (7 * 8)/2
(7 * (8/2)) = 7 * 4 = 28
28 is your answer.

Answer: 15/8
Step-by-step explanation:
First we can do the subtraction:
2 - 1/8 = 1 7/8
Next we multiply 1 by 8 and add it to the 7,
1 x 8 +7 = 15, so therefore it’s 15/8, please give me a thanks and 5 stars along with brainliest!
3/8 + 1/16= 7/16
so it's c. 7/16
Answer:
x=3, y=-6
Step-by-step explanation:
As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!
Let’s begin with our detailed answer:
As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.
So in our system of equations:
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
To eliminate this question we can divide the top part by -3:
![\left \ {-9x-6y=9}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B-9x-6y%3D9%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
Let‘s sum these system of equation and we get: ![y=-6](https://tex.z-dn.net/?f=y%3D-6)
We can now insert y as -6 and solve for x:
![3x-12=-3](https://tex.z-dn.net/?f=3x-12%3D-3)
![x=3](https://tex.z-dn.net/?f=x%3D3)
So, ![x=3, y = -6](https://tex.z-dn.net/?f=x%3D3%2C%20y%20%3D%20-6)
