Solution:
Vertical angles are a pair of opposite angles formed by intersecting lines. re vertical angles. Vertical angles are always congruent.
These two angles (140° and 40°) are Supplementary Angles because they add up to 180°:
Notice that together they make a straight angle.
Hence,
From the image
The following pairs form vertical angles
Hence,
One pair of the vertical angles is ∠1 and ∠3
Part B:
Two angles are said to be supplementary when they ad together to give 180°
Hence,
From the image,
The following pairs are supplementary angles
Hence,
One pair of supplementary angles is ∠5 and ∠6

Answer:
Step-by-step explanation:
We want to prove algebraically that:
is a parabola.
We use the relations
and
Before we substitute, let us rewrite the equation to get:
Or
Expand :
We now substitute to get:
This means that:
Square:
Expand:
This is a parabola (0,2.5) and turns upside down.
Answer:
400 - 15x < 300
Step-by-step explanation:
We are told that she has 400$ in her bank account.
Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.
Total total withdrawal each week = 10 + 5 = $15
If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.
Thus, amount left after x number of weeks is:
400 - 15x
We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.
Thus;
400 - 15x < 300
