Part A: The answer is PR = 15.23 by Pythagorean Theorem.
The pythagorean theorem is a^2 + b^2 = c^2.
Plug in 14 for a and 6 for b to find c.
Part B: The answer is QR = 7.75.
Using the same theorem, plug 16 in for c, 14 in for a, and then you can find b.
Answer:
Rounding x = 5.52
Step-by-step explanation:
2.1x - 3.6 = 8
Add 3.6 to each side
2.1x - 3.6+3.6 = 8+3.6
2.1x = 11.6
Divide each side by 2.1
2.1x/2.1 = 11.6/2.1
x =5.523809524
Rounding x = 5.52
Answer:
C
Step-by-step explanation:
First, you need to rewrite the equation.
-3x+8y=12
8y=12+3x
y=3/2+3/8x
The slope is the coefficient of x, which is 3/8.
