Answer:
The coordinates of point S are (8,-2)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
Let
Point S(x2,y2)
substitute the given values
<em>Solve for x2</em>
<em>Solve for y2</em>
therefore
The coordinates of point S are (8,-2)
The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

Answer:
x=-3
Step-by-step explanation:
Answer choice A is a vertical line through the the x-axis crossing through -3. It has an x-intercept of -3.
Answer choice B is a horizontal line through the y-axis crossing through -3. It has no x-intercpet.
Answer choice C is a horizontal line through the y-axis crossing through 7. It has no x-intercept.
Only A has an x-intercept of -3.
Answer:
around 200.96
Step-by-step explanation:
circle area = pir^2
pi*8^2
