Answer:
- 5 ≤ x < 3
Step-by-step explanation:
The lower limit has a solid circle at - 5
This means that x can equal - 5
The upper limit has an open circle at 3
This means that x cannot be equal to 3
The inequality represented by the diagram is then
- 5 ≤ x < 3
Answer:
<h2>B. 224</h2>
Step-by-step explanation:
![\text{Put x = 4 and y = 2 to the expression}\ 7x^2y:\\\\7(4^2)(2)=7(16)(2)=224](https://tex.z-dn.net/?f=%5Ctext%7BPut%20x%20%3D%204%20and%20y%20%3D%202%20to%20the%20expression%7D%5C%207x%5E2y%3A%5C%5C%5C%5C7%284%5E2%29%282%29%3D7%2816%29%282%29%3D224)
3x+2y= -8
multiply by 3 to,x-y= -1
so u will get,
3x+2y= -8
-3x+3y=+3,eliminating both of them you will get,
5y= -5
y = -1
by applying the value of y,
3x+2*-1= -8
3x - 2= -8
3x= -5
x = -5/3
