y = mx + c

First find the gradient.

6 - 2 = 4

Your gradient, m, is 4x.

Now find the constant, c.

y = mx + c

if y = 4 and x = 2

4 = 4 * 2 + c

4 = 8 + c

4 = 8 - 4

c = -4

You can check it's right by substituting the other values.

y = 4x - 4

E.G

36 = 4 * 10 - 4

36 = 40 - 4

In Part C, you determined that the proper ratio of packages of buns, packages of patties, and jars of pickles is 3:2:4. If you w

andrew-mc [135]

Answer:

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

Step-by-step explanation:

packages of buns = 3

packages of patties = 2

Jars of pickles = 4

Number of people = 420

Each person of the 420 people gets packages of buns, packages of patties, and jars of pickles in the ratio 3:2:4

packages of buns needed for 420 people = 3 × 420

= 1,260

packages of patties needed for 420 people = 2 × 420

= 840

Jars of pickles needed for 420 people = 4 × 420

= 1,680

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

To feed at least 420 people minimum number of packages of buns, packages of patties, and jars of pickles needed is 1,260, 840, 1,680 respectively.

Let x^2−12x=61 . What values make an equivalent number sentence after completing the square? Enter your answers in the boxes.

tatyana61 [14]

Complete the square:

x^2 - 12x + (-6)^2 - (-6)^2 = 61, or
(x-6)^2 -36 = 61, or

x-6 = plus or minus sqrt(97), or

x = 6 plus or minus sqrt(97)

given the following information, determine which lines, if any, are parallel. state the converse that justifies your answer.

frozen [14]

From the information in the diagram found in a similar question online (please see attached drawing), the parallel lines are;

w||z
x||y
x||y
w||z
w||z
x||y
x||y
w||z
x||y
w||z

<h3>What are the relationships between angles formed by parallel lines?</h3>

Parallel lines are lines that do not meet, when extended indefinitely.

The possible information given as obtained from a similar question posted online are;

1. ‹1 is congruent to ‹5

2. ‹7 is congruent to ‹9

3. m‹8 + m‹9 = 180°

4. ‹16 is congruent to ‹14

5. m‹1 + m‹4 = 180°

6. ‹3 is congruent to ‹13

7. ‹2 is congruent to ‹10

8. ‹11 is congruent to ‹15

9. m‹4 + m‹13 = 180°

10. ‹8 is congruent to ‹6

1. Given that ‹1 is congruent to ‹5 where ‹1 and ‹5 are alternate exterior angles, we have that line w is parallel to line z

w||z

Theorem (converse); Alternate exterior angles formed by two parallel lines having a common transversal are congruent.

2. ‹7 and ‹9 are alternate interior angles.

Given that ‹7 is congruent to ‹9, therefore;

Line x is parallel to line y

x||y

Theorem (converse); Alternate interior angles formed by two parallel lines having a common transversal are congruent.

3. Given that m‹8 + m‹9 = 180°, therefore;

‹8 and ‹9 are supplementary angles, formed between lines x and y.

‹8 and ‹9 are also consecutive interior angles.

Theorem (converse); Consecutive interior angles formed between parallel lines are supplementary.

Therefore;

x||y

4. ‹16 and ‹14 are corresponding angles formed by lines w and z.

Theorem (converse); Corresponding angles formed by parallel lines are congruent.

Given ‹16 congruent to ‹14, we have;

w||z

5. m‹1 and m‹4 are consecutive exterior angles formed by lines w and z.

Theorem (converse); Consecutive exterior angles formed by two parallel lines are supplementary.

Given that m‹1 + m‹4 = 180°, we have;

w||z

6. ‹3 and ‹13 are alternate exterior angles formed by lines x and y.

Theorem (converse); Alternate exterior angles formed by parallel lines are congruent.

Given that ‹3 congruent to ‹13, we have;

x||y

7. ‹2 and ‹10 are corresponding angles formed by lines x and y

Given that ‹2 congruent to ‹10, therefore;

x||y

8. ‹11 and ‹15 are alternate interior angles formed by lines w and z.

‹11 is congruent to ‹15, therefore;

w||z

9. ‹4 and ‹13 are consecutive exterior angles formed by lines x and y

m‹4 + m‹13 = 180°, therefore;

x||y

10. ‹8 and ‹6 are corresponding angles formed by lines w and z.

‹8 is congruent to ‹6, therefore;

w||z
