Answer:  D.8

Step-by-step explanation:

y-intercept means the point of the line crosses the y-axis, where x = 0.

y = mx + b represent most linear equation, where m is the slope and b is the y-intercept.

Step 1: Find the slope of the line, choose two points: (-2,16) and (1,4).

slope = \frac{y2-y1}{x2-x1} = \frac{4-16}{1-(-2)} = \frac{4-16}{1+2} = -12/3 = -4

Step 2: Solve b by choose one point to plug in. (1,4)

y = mx + b

4 = -4(1) + b  [Plug in the value of x, y, and slope]

4 = -4 + b     [Add 4 on both sides]

8 = b

Therefore, the y-intercept is D.8

3 A farmer has 580 square bales of hay in his shed with total mass 9850 kg.
rusak2 [61]

Answer:

a) 580 - 16n

b) 9850 - 271.72n

Step-by-step explanation:

a) starting number of bales = 580

each day, the farmer feeds out 2 bales of hay to each yard. he has 8 yards, so he feeds out 2 bales 8 times for a total of 2 * 8 = 16 bales. Therefore, he loses 16 bales each day

After the first day, he has 580-16 = 564 bales. After the second, he has 564-16 = 548 bales, and so on. He loses 16 bales n times for n days, and as a result, his final amount of bales is

original amount - amount lost = 580 - 16n

b)

First, we can calculate how much a bale weighs.

average = sum/count = 9850 kg / 580 ≈ 17 kg

Therefore, as he loses 16 bales of hay, he loses 17 kg 16 times, or approximately 271.72 kg of hay every day. For n days, he loses 271.72n kg. This brings his final amount to be

starting - amount lost = 9850 - 271.72n

Write the converse of the following statement. Then determine its validity.
madam [21]

The converse and the validity of the statement is:

  • If a parallelogram is a rectangle, then the diagonals are congruent.
  • TRUE.

The statement is given as:

If the diagonals of a parallelogram are congruent, then is the parallelogram is a rectangle

Considering the following statement

If a then b

Its converse is:

If b then a

So, the converse of the given statement is:

If a parallelogram is a rectangle, then the diagonals are congruent.

The diagonals of a rectangle are true.

Hence, the validity is true.

So, the true statement is (b)

Which steps will generate an expression equivalent to 17(+5)
Bingel [31]

For this case we must indicate an expression equivalent to:

17 (x + 5)

By definition we have that the distributive property establishes that:

a (b + c) = ab + ac

Then, applying the property to the given expression we have:

17 (x + 5) = 17 * x + 17 * 5 = 17x + 85

Thus, an equivalent expression is:

17x + 85

ANswer:

17x + 85
