A line passes through the points (4,15) and (9,20). Right in line your function rule in terms of x and y for this line

Answers

Answer:

15

Step-by-step explanation:

use formula y-y1=m(x-x1)

(4,15) = (x1,y1)
(9,20)=(x2,y2)

m is the slope which you don’t have but you can find by doing (y2-y1)/(x2-x1)
m=(20-15)/(9-4)
m=5/5
m=1

y-y1=m(x-x1)
y-15=1(x-4)
y-15=x-4 |+15 to both sides
y=x +11

Answers

Answer:

A. 2

Step-by-step explanation:

Given:

DC = 1

CE = x + 4

AB = 11

BE = x + 1

Required:

Value of x

Solution:

(DC + CE) × CE = (AB + BE) × BE

(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)

(x + 5) × (x + 4) = (x + 12) × (x + 1)

x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)

x² + 9x + 20 = x² + 13x + 12

Collect like terms

x² - x² + 9x - 13x = - 20 + 12

-4x = -8

Divide both sides by -4

x = -8/-4

x = 2

A towns population went from 40,000 to 50,000. What was the percent of change in the population?

Answers

Answer:

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

Please give me the correct answers​

Answers

Answer:

x = 25°

y = 25°

Step-by-step explanation:

✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)

x + 35 + 30 + 90 = 180

Add like terms

x + 155 = 180

x + 155 - 155 = 180 - 155

x = 25°

✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)

y + 155 = 180

y = 180 - 155

y = 25°

Answers

Answer:

0.6 km

Step-by-step explanation:

If If you jog 8 times around a track that is 600 meters long, then 4.8  kilometers you  have covered

What is Unit of Measurement?

A Unit of measure is the actual unit in which the associated values are measured.

Given,

If you jog 8 times around a track that is 600 meters long,

We need to find how many kilometers you have covered.

8 times around a track that is 600

It means we have to multiply eight with six hundred.

8×600

=4800

We know that 1 km is 1000 m

So divide 4800 by 1000 to find in kilometers

4800/1000=4.8km

Hence If you jog 8 times around a track that is 600 meters long, Then 4.8  Kilometers you have covered.

2. The German Shepard actually weighs 28 pounds. Lisa thought the
dog weighed 44 pounds. What is the percent error?

Answers

Answer:

Lisa's percentage of error regarding the weight of the dog was 57.14%.

Step-by-step explanation:

Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:

28 = 100

44 = X

(44 x 100) / 28 = X

4,400 / 28 = X

157.14 = X

157.14 - 100 = 57.14

Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

Answer:

  B.  2,022

Step-by-step explanation:

The student/faculty ratio tells you the total number of students in the school is ...

  upper-level students = 2685 -663 = 2022

The total number of upper-level students is 2,022.
