If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.
The formula of a slope:
PQ → (0, 3), (2, 0).
Substitute:
QR → (2, 0), (4, -3).
Substitute:
CORRECT :)
<h3>Answer: m = -1.5.</h3>
Answer:
CE = 36
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
AS = CE , substitute values
2x + 10 = x + 23 ( subtract x from both sides )
x + 10 = 23 ( subtract 10 from both sides )
x = 13
Then
CE = x + 23 = 13 + 23 = 36
Answer:
total bill amount + tip = $77.21
Step-by-step explanation:
base: b
height: b
A = 1/2 (b · b) = 1/2(b²) = b²/2
sum is six less than area
b + b = 6 - ↔b²/2
2b = b²/2 - 6
4b = b² - 12 <em>multiplied by 2 to clear the denominator</em>
0 = b² - 4b - 12
0 = (b - 6)(b + 2)
0 = b - 6 0 = b + 2
b = 6 b = -2 (Negative so disregard)
A = b²/2 = (6)²/2 = 36/2 = 18
Answer: 18 units²
