Question:
Consider ΔABC, whose vertices are A (2, 1), B (3, 3), and C (1, 6); let the line segment AC represent the base of the triangle.
(a) Find the equation of the line passing through B and perpendicular to the line AC
(b) Let the point of intersection of line AC with the line you found in part A be point D. Find the coordinates of point D.
Answer:


Step-by-step explanation:
Given




Solving (a): Line that passes through B, perpendicular to AC.
First, calculate the slope of AC

Where:
--- 
--- 
The slope is:



The slope of the line that passes through B is calculated as:
--- because it is perpendicular to AC.
So, we have:


The equation of the line is the calculated using:

Where:

--- 

So, we have:

Cross multiply




Make y the subject

Solving (b): Point of intersection between AC and 
First, calculate the equation of AC using:

Where:
--- 

So:



So, we have:
and 
Equate both to solve for x
i.e.


Collect like terms

Multiply through by 5

Collect like terms

Solve for x


Substitute
in 


Take LCM


Hence, the coordinates of D is:

It takes 5 minutes to read a passage that has 800 words with the same speed.
<u>SOLUTION:
</u>
Given that, during a reading test, Enrique reads a passage with 640 words. It takes him 4 minutes to read the passage.
We have to find time taken by Enrique to read a passage that has 800 words if he reads at the same speed
Now, we know that,

Then, 
So, by cross multiplication method

Cross multiplications steps: (To find Single Variable)
Step 1: Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction.
Step 2: Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
Step 3: Set the two products equal to each other.
Step 4: Solve for the variable.
No es el 3 pero si es el numero 7
Answer:
You cannot solve for x here.
Step-by-step explanation:
Given: y = 6 + 0x.
This is equivalent to y = 6.
y = 6 is the equation of a horizontal line that crosses the y-axis at y = 6. This equation is true for any x value.
So, no, you cannot solve for x here.
