Write the equation of the line passing through the points (-5,6) and (-6,5)

Answers

Step-by-step explanation:

(y+6)=(11/12)(x+6)

after finding the slope, plug in one point into the point slope form of a line.

m=( y2 - y1)/(x2 - x1)

m=(-6-5)/(-6-6)

m= 11/12

Equation of line

(y-6)/(x-5)=11/12

12y+11x = 17

The equation of the line passing through the point (-5, 6) and (-6, 5) is

y = x + 11.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Points:

(-5, 6) and (-6, 5)

Slope.

= (5 - 6) / (-6 + 5)

= -1 / -1

= 1

Now,

Equation of a line.

y = mx + c

keep (-5, 6) = (x, y)

6 = 1 x -5 + c

6 = - 5 + c

c = 6 + 5

c = 11

Now,

y = mx + c

y = x + 11

Thus,

The equation of the line is y = x + 11.

What is the relationship between the degree of a function and the degree of the derivative?​

Answers

Answer:

Graphing the derivative with the function can illustrate how to find these turning points. The function is increasing exactly where the derivative is positive, and decreasing exactly where the derivative is negative. On the graph of the derivative find the x-value of the zero to the left of the origin.

I need some help... Sarah's teacher wrote this expression on the whiteboard. 24 ÷ 6 − 2 × 5 + 6 Where could she place brackets in the expression for it to be equal to 36? A. 24 ÷ [6 − 2] × 5 + 6 B. 24 ÷ 6 − [2 × 5 + 6] C. [24 ÷ 6] − 2 × 5 + 6 D. 24 ÷ 6 − 2 × [5 + 6]

Answers

Answer:

A. 24 ÷ [6 − 2] × 5 + 6

Step-by-step explanation:

We are given the expression:

24 ÷ 6 − 2 × 5 + 6

Where could she place brackets in the expression for it to be equal to 36?

We have to follow a rule in mathematics that is referred to as :

PEMDAS

P = Parentheses (Brackets)

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction.

When given a mathematical expression with a lots of operations embedded in it, we use PEDMAS rule to solve for it correctly.

Option A 24 ÷ [6 − 2] × 5 + 6 is the correct Option to give us 36. This is because, following the PEDMAS rule.

P = Parentheses comes first

24 ÷ [6 − 2] × 5 + 6

= 24 ÷ 4 × 5 + 6

Division comes next

24 ÷ 4 × 5 + 6

= 6 × 5 + 6

Multiplication comes next

6 × 5 + 6

= 30 + 6

Finally , Addition

= 36.

Therefore, Option A is the correct Option, that shows us where the brackets should be placed to give us 36

one acute angle of right angled triangle is 63 degree find the other angle in degree​

Answers

Answer:

x =27

Step-by-step explanation:

A right triangle has a 90 degree angle. It also has a 60 degree angle

The sum of the angles of a triangle are 180.

90+63+x = 180

153+x = 180

Subtract 153 from each side

x = 180-153

x =27

Cheryl paid 37.20 for 12 gallons of ice cream for a school picnic how much would one quart of cream cost

Answers

Answer:

$.775 for a quart

Step-by-step explanation:

Kirstin knows that the initial fee for adopting a dog from the animal shelter is $75. This fee needs to be considered when calculating how much a dog will cost. Write a function, C(d), to represent the cost to adopt and feed the dog in terms on the number of days (d) that kirstin owns her dog

Answers

Answer:

The function is represented by [tex]C(d) = 75\,USD + r\cdot d[/tex].

Step-by-step explanation:

In this case, we must observe that total cost of the dog ([tex]C(d)[/tex]) is the sum of two components: i) Fixed cost ([tex]C_{f}[/tex]) - Adoption fee, ii) Variable cost ([tex]C_{v}[/tex]) - Daily cost of feeding the dog, both measured in US dollars.

In addition, we suppose that variable cost is directly proportional to the number of days that Kirstin owns her dog. That is:

[tex]C (d) = C_{f} + C_{v}[/tex]

[tex]C(d) = C_{f} + r\cdot d[/tex]

Where:

[tex]d[/tex] - Number of days that Kirstin owns her dog, measured in days.

[tex]r[/tex] - Daily feeding costs, measured in US dollars per day.

If [tex]C_{f} = 75\,USD[/tex], then:

[tex]C(d) = 75\,USD + r\cdot d[/tex]

The function is represented by [tex]C(d) = 75\,USD + r\cdot d[/tex].
