Hollis house is located at (-1,4). She can walk in a straight line to get to Jedds house. A fast food resturant is located at (-

Nezavi [6.7K]

Answer:

The coordinates of Jedds house are (-7 , -2)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (x , y) divide the distance between the two points

$(x_{1},y_{1})$ and $(x_{2},y_{2})$ at the ratio

$(m_{1}:m_{1})$ , then

$x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}$ and

$y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}$

* Lets solve the problem

∵ Hollis house is located at (-1 , 4)

∴ $(x_{1},y_{1})$ = (-1 , 4)

∵ She can walk in a straight line to get to Jedds house

∵ The restaurant is located at (-3 , 2) and partitions the way from

Hollis house to Jedds house by a ration of 1 : 2

∴ (x , y) = (-3 , 2)

∴ $(m_{1}:m_{1})$ = 1 : 2

- Lets consider that Jedds house is located at $(x_{2},y_{2})$

∴ $-3=\frac{-1(2)+x_{2}(1)}{1+2}$

∴ $-3=\frac{-2+x_{2}}{3}$

- Multiply both sides by 3

∴ $-9=-2+x_{2}$

- Add 2 for both sides

∴ $-7=x_{2}$

∴ $2=\frac{4(2)+y_{2}(1)}{1+2}$

∴ $2=\frac{8+y_{2}}{3}$

- Multiply both sides by 3

∴ $6=8+y_{2}$

- Subtract 8 for both sides

∴ $-2=y_{2}$

∴ The coordinates of Jedds house are (-7 , -2)

Use any method to add or subtract 5/7 {3/14+3/14}

OlgaM077 [116]

Answer:

15/49

Step-by-step explanation:

5/7 (3/14 + 3/14)

first combine like terms

3/14 + 3/14 = 6/14

then simplify by 2

6/14 to 3/7

now that both the term inside and outside have the same denominator, multiply

5/7 x 3/7 = 15/49

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2)

MrMuchimi

Answer:

y = -2x + 2

General Formulas and Concepts

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

y-intercept (0, 2)

Step 2: Find slope m

Substitute: $m=\frac{2-4}{0+1}$
Subtract/Add: $m=\frac{-2}{1}$
Divide: $m=-2$

Step 3: Write linear equation

y = -2x + 2

Can someone please help me

It would be 30 degrees since a line is 180. You subtract 150 from 180 and get 30.
