So slope intercept form is y=mx+b.
So the equation of the line is:
y= -4x - 3
Hope this help!
Answer:
The Answer is 33,300$ Hope This Helps!
Step-by-step explanation:
i know this because a trimester is 3 times a year and if she is paying 2,350$ a trimester i know she is paying 7,050$ a year so multiply that by 4 and you get 28,200$ so do the same thing I just explained with the books and you get 33,300$ Have a great day!
Solution: For finding QR we need to apply Pythagoras Theorem
What is Pythagoras Theorem ?
ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°
According to this law let's apply it in the diagram shown here.
- (Hypotenuse)² = (Adjacent)² + (Opposite)²
- (5x - 2)² = (QR)² + (3x - 1)²
- (QR)² = (5x - 2)² - (3x - 1)²
After factorising both of them we get
- (QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)
- (QR)² = 25x² - 20x + 4 - 9x² + 6x - 1
So, QR is √(16x² - 14x + 3)
The answer is 8cm you just have to add all the sides
