Answer:
The answer to your question is: x = 27
Step-by-step explanation:
The are vertical angles, so they measure the same:
4x + 7 = 5(x - 4)
4x + 7 = 5x - 20 Expanding
4x - 5x = -20 - 7 Simplify like terms
-x = -27
x = 27

========================================
Explanation:
If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).
Relations 1 and 3 don't have this issue, so they are functions.
The formula for solving volume of a pyramid is shown below:
Volume = l*h*w / 3
18 = l*h*w/3
Originally, it is given that the volume of a pyramid is 18 inches³. If we are supposed to multiply all measurements by 6, we can attain new volume and solution is shown below:
New volume = 6³l*w*h /3
New volume = 6³ (18)
New volume = 3,888 in³
The answer is 3,888 inches³.
Answer:
Well, I'm unsure of exactly what you're looking for but slope intercept form is y=mx+b
Step-by-step explanation:
y=mx+b
m=slope
b=y intercept (y intercept is where on the graph the line crosses with the y-axis)
This means that the y intercept is (0, -3)
Then you have the slope: Rise/Run
Run=x axis
Rise= y axis
So if you were to graph y=-1/2x-3 you would find the y intercept (0,-3)
then, because it is negative 1/2, you would move two units to the left, and one unit down (-2,-1)
Hopefully this helps you out a bit. Apologies if anything was incorrect I'm not the greatest with this. :)
