Answer:
These 2 points on a graph are 17 units apart.
Step-by-step explanation:
Y Coordinate is the same for both points, all you need to know is the change in X coordinates.
Answer:
v = 25
Step-by-step explanation:
The crucial information you need to know to solve this is to realize that HI and GH are the same length. However, why they are equal is not immediately obvious.
Both sides of the middle line (HF) are symmetrical, since G and I are the same distance away from the line, and they both lie on a line perpendicular to the middle line.
Note: we know they're the same distance away due to the small red marks in the lines, indicating that they're the same length.
The angles at G and I in the triangles are also the same, as the lines from G and I both meet at H. If they were different angles, they would each hit a different point on the middle line.
Thus, we can conclude that GH and HI are the same length.
Since we know the following:
GH = 4v - 75
HI = v
We can set GH and HI equal to each other and solve the equation.
4v - 75 = v
Subtract v from both sides:
3v - 75 = 0
Add 75 to both sides:
3v = 75
Divide both sides by 3:
v = 25
Answer: v = 25
Answer:
Step-by-step explanation:
the polynomial function is; (x - i)(x-2)(x+2)
Answer:
Step-by-step explanation:
Let's solve one of them for x.
Add 4
Divide by 3.
Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.
Multiply by 3 to get rid of the denominator.
add x
Combine like terms;
Divide by 4.
Simplify.
Now that you found the value of x, replace it in any of the equations to find y.
Proof:
Answer:
1
Step-by-step explanation:
Any number divided by itself equals 1. So, 23 divided by 23 is 1.
