Answer:
Point Form:
(-1/4, -7/8)
Equation Form:
x= -1/4, y= -7/8
Step-by-step explanation:
I just encountered this question. Here's my answer.
Given:
Segment AC = 130 feet
Segment CD = 70 feet
I think that I'll be using the Pythagorean Theorem in finding the value of r. r will be the hypotenuse
Segment CE = (r - 70 feet)
r² = a² + b²
r² = 130² + (r-70)²
r² = 16,900 + (r-70)(r-70)
r² = 16,900 + r² - 70r - 70r + 4900
r² - r² + 140r = 16,900 + 4,900
140r = 21,800
r = 21,800/140
r = 155.71 feet

Answer:
Step-by-step explanation:
To get the final answer, isolate the variable y on one side of the equation.
<h3>1/4y≥8</h3>
First, multiply by 4 from both sides.
Solve.
8*4=32
- <u>Therefore, the correct answer is D.</u>
