Answer:
18
Step-by-step explanation:
To find volume you have to use the formula (length x width x height.)
So by looking at it you can see that it's 3 units long, 3 units in wide, and 2 units tall. Knowing that, you then plug in those numbers to the formula. That would be 3x3x2. Any calculator will work.
Answer:
y=-3x+10
Step-by-step explanation:
Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

Answer:
Step-by-step explanation:
There is nothing you could put into the brackets that will give you a negative answer. We should just graph this to see if that is true or not. Graphs are the last word in this kind of question.
See below.
The graph is the first part: y = |5x +7|
It is the red graph.
The second line of interest is y = - 7. It is blue.
Do you see that these two graphs do not intersect?
Because they don't, there is no solution. Any marker will accept this explanation and the graph. You should be fine with just this much.
