The y intercept means , the estimated amount of feed per day for the start of the farm , Option C is the right answer.
What is a function ?A function is a law that relates two variables , independent and dependent variable.
It is given that
On y axis , amount of feed used each day in thousands of pounds,
On x axis, number of years since the farm began operating
The y intercept means x = 0 , which means at the starting of the farm , the feed needed per day.
Therefore Option C is the right answer , the estimated amount of feed per day for the start of the farm.

Which number is in the solution set of the inequality -5x - 7 > 28?
Answers
Hello!
Answer:
[tex]\Large \boxed{\sf A. -7}[/tex]
Step-by-step explanation:
We have this inequality:
[tex]\sf -5x - 7 \geq 28[/tex]
Let's solve this inequality:
◼ Add 7 to both sides:
[tex]\sf -5x - 7+7 \geq 28+7[/tex]
◼ Simplify both sides:
[tex]\sf -5x \geq 35[/tex]
◼ Divide both sides by -5, so also change the sign of the inequality
[tex]\sf \dfrac{-5x}{-5} \leq \dfrac{35}{-5}[/tex]
◼ Simplify both sides:
[tex]\boxed{\sf x \leq -7}[/tex]

A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry.
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
2. Find the value of the supplementary angle of y for each polygon.
A.) For an isosceles triangle, using the base angle theorem we can write that the measure of the angle opposite to the congruent side will be equal. Therefore, the sum of the angles of the triangle can be written as,
y + y + 26° = 180°
2y = 154°
y = 77°
B.) The sum of the interior angles of a regular polygon is given as (n-2)180°, where n is the number of sides, also for a regular polygon the measure of each interior angle is equal. Since in a pentagon the number of sides is 5. Therefore, the measure of an interior angle can be written as,
y = [(n-2)180°]/n
y = [(5-2)180°]/5
y = 108°
3. The sum of the exterior angle of all the polygons is equal to 360°. Therefore, the sum of the exterior angles of the triangle and the pentagon will be the same, 360°
4. The formula to find the sum of the interior angles of a polygon, we can use the formula.
Sum of interior angles of an n-sided polygon = (n-2)180°
Where n is the number of sides.

2 triangles are shown. The first triangle has side lengths 35, 20, and 20. The second triangle has side lengths x, 44, 44.
What value of x will make the triangles similar by the SSS similarity theorem?
Answers
The value of x is 77 cm which will make the triangles similar by SSS similarity theorem
Given length of the three sides of one triangle are 35 , 20 and 20
and length of the three sides of another triangle are x, 44,44
We need to find the values of x by using SSS Similarity theorem
We know that triangles are are similar by side - side - side similarity creation and hence the sides are in the same ratio
As both the triangles are isosceles triangles
Therefore ,
x/35 = 44/20=44/20 (Using ratio)
Solving the equation we get
x=44*35/20
x= 77
Hence the value of x is 77cm
