Answer:
B
Step-by-step explanation:
THis is a single equation with a single variable [y].
We can separate the variable in one side and the numbers to another and solve for y. Shown below:
3y + 4 = -2
3y = -2 - 4
3y = -6
y = -6/3
y = -2
THus, this equation has only 1 solution. B is correct
Answer:
200 in3
Step-by-step explanation:
To find the volume of a rectangular prism you multiply each dimension to each other. 8*2 is 16, and 16*12.5 is 200. This means the volume is 200 in3.
Hope this helps :)
Answer:
The inverse is g(x)=-x+5.
Both f and g have domain and range all real numbers.
In interval notation that is 
Step-by-step explanation:
f(x)=-x+5 is a linear function.
Since isn't f(x)=constant then it is diagonal so this means the range is all real numbers.
For any linear function, the domain will be all real numbers.
So to find the inverse of y=-x+5, you interchange x and y and resolve for y.
y=-x+5
(interchange)
x=-y+5
(solve for y)
Subtract 5 on both sides:
x-5=-y
Multiplying both sides by -1:
-x+5=y
So the inverse is g(x)=-x+5. To find find the domain and range of the inverse function given you already did it for the original function, the sets are swapped. The sets were the same here because they were both all real numbers.
Answer:
Step-by-step explanation:
2 surfaces that are 5x7
2 surfaces that are 4x7
and the top and bottom that are 4x5
2*5*7 = 70
2*4*7 = 56
2*4*5 = 40
total surface is 166
