how do I find b with the equation y=0.023x + b using the points (0, 11.08) and (1,11.06)

Answers

Answer 1

To find b in the equation y = 0.023x + b, you have to replace with a given point into the equation. For example, point (0, 11.08) means x = 0 when y = 11.08, replacing into the formula:

11.08 = 0.023*0 + b

11.08 = b

What is isosceles triangle ?

Triangles that have two sides at least equally spaced apart are said to be isosceles. As three-sided enclosed polygons with three sides, triangles are known to exist. Depending on the length of their sides, triangles can be categorized as equilateral, isosceles, or scalene.

The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°).

So ,

x +x+38 = 180

2x = 180 -38

2x = 142

x = 71

Answer:

A

Step-by-step explanation:

Answer:

h = 2

k = 5

Step-by-step explanation:

Midpoint between two points

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

Given:

B = Midpoint = (6, 0)A = (x₁, y₁) = (3h+4, 1-2h)C = (x₂, y₂) = (k-3, k-2)

Substitute the given values into the formula:

[tex]\implies (6, 0)=\left(\dfrac{k-3+3h+4}{2},\dfrac{k-2+1-2h}{2}\right)[/tex]

[tex]\implies (6, 0)=\left(\dfrac{k+3h+1}{2},\dfrac{k-2h-1}{2}\right)[/tex]

Equating the x-values to create an expression for k:

[tex]\implies \dfrac{k+3h+1}{2}=6[/tex]

[tex]\implies k+3h+1=12[/tex]

[tex]\implies k+3h=11[/tex]

[tex]\implies k=11-3h[/tex]

Equating the y-values to create an expression for k:

[tex]\implies \dfrac{k-2h-1}{2}=0[/tex]

[tex]\implies k-2h-1=0[/tex]

[tex]\implies k-2h=1[/tex]

[tex]\implies k=2h+1[/tex]

Equate the expressions for k and solve for h:

[tex]\implies 2h+1=11-3h[/tex]

[tex]\implies 5h=10[/tex]

[tex]\implies h=2[/tex]

Substitute the found value of h into one of the equations for k and solve for k:

For the second inequality,

Never the distance is not defined as negative by definition of distance.

Yes, it is proportional because the ratios for miles per hour are all equivalent to 1.25 miles per hour.
Yes, it is proportional because the ratios for miles per hour are all equivalent to 0.8 miles per hour.
No, it is not proportional because 3.75 miles in 3 hours is not equivalent to 7.5 miles in 6 hours.

Answers

Answer:

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Step-by-step explanation:

first lets find out how far they hiked per hour3.75 mi in 3 hourswe need to do 3.75÷3= and we get 1.25 mi an hour now we need to do the next oneit is 7.5 mi in 6 hoursso we are gonna do 7.5÷6=and we get 1.25 mi an hournow lets do the last one12 mi in 8 hourswe are gonna do 12÷9=and we get 1.5 mi in an hourso the 3 hours and 6 hour are proportional so it would be: No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

A group of hikers tracked how long it took to hike a 20-mile trail.

And, They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.

Now,

Find the proportional as;

For hiked 3.75 miles in 3 hours,

Proportional = 3.75 / 3

                   = 1.25

For hiked 7.5 miles in 6 hours,

Proportional = 7.5 / 6

                   = 1.25

For hiked 12 miles in 8 hours,

Proportional = 12 / 8

                   = 1.5

Thus, The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Proportion

The proportion can be written different ways. We like to put the unknown value in the numerator. (x is the number of parts of yellow paint)

If you kept the proportion as violet : yellow, then the unknown value would be in the denominator. The solution to that proportion requires another step. Here, we just needed to multiply by the denominator value to find the unknown.
