Answer:

-2/3

Step-by-step explanation:

Since slope is just rise over run, find the y intercept and see how far it is from the x axis. If it goes down and is above \the x axis, then it is negative and if it is under the x axis, then it is positive. Then count how far the x intercept is. Same concept as the y intercept. Then, you put it as a fraction (y goes on top of x) and simplify to get your slope.

Find the slope of the line that is (a) parallel and (b) perpendicular to the line through the pair of points.

ddd [48]

Answer:

a) The slope of the line is parallel to the another line m=4

b) The slope of the line is perpendicular to the another line m= $\frac{-1}{4}$

Step-by-step explanation:

Step1:-

Slope of a line :-

If θ is the inclination of a line 'l' then tanθ is called the slope or gradient of the line 'l'.The slope of a line is denoted by m=tanθ

The slope of a line given two points m= $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

Parallel lines:-

Two non-vertical lines are parallel if and only if their slopes are parallel

Perpendicular lines:-

Two non-vertical lines are perpendicular to each other if and only if their slopes are negative reciprocals of each other.

$m_{2} = \frac{-1}{m_{1} } \\$

Step 2:-

a)The slope of a line when given two points (-1,-4) and (0,0)

$m = \frac{0-(-4)}{0-(-1)} =4$

Two non-vertical lines are parallel if and only if their slopes are parallel

$m_{1} = m_{2}$

Therefore the slope of the line that is parallel to the another line

$m_{1} =m_{2} =4$

Step 3:-

b) Two non-vertical lines are perpendicular to each other if and only if their slopes are negative reciprocals of each other.

$m_{2} = \frac{-1}{m_{1} } \\$

$m_{2} =\frac{-1}{4}$

Therefore the slope of the line is perpendicular to the another line is

$m=\frac{-1}{4}$

Please help!!!! i will give max points i can

mixer [17]

Answer:

Step-by-step explanation:

These are given:

Total = 22

Cost for shoes = 4

Total games played = 2

Cost per game (g)= ?

So,

22 = 4 + 2(g)

-4 -4

18 = 2g

divide by 2

9 = g

$9 per game

Answer:

I think it goes like this : 20:4=5 so there's five monsters in the room

Step-by-step explanation:

if that's the case of this question it should go like this:

9(rooms)×5(monsters per room)= 45 monsters

30(monsters):5(monsters per room)=6 rooms

13(rooms)×5(monsters per room)=65 monsters

35(monsters):5(monsters per room)=7 rooms

I hope you do well in your assignment.

I hope I helped at least a little!

Sofia invests her money in an account paying 7% interest compounded semiannually. What is the effective annual yield on this acc

vfiekz [6]

Answer:

7.12

Step-by-step explanation:

The formula for the effective annual yield is given as:

i = ( 1 + r/m)^m - 1

Where

i = Effective Annual yield

r = interest rate = 7% = 0.07

m= compounding frequency = semi annually = 2

i = ( 1 + 0.07/2)² - 1

i = (1 + 0.035)² - 1

= 1.035² - 1

= 1.071225 - 1

= 0.071225

Converting to percentage

0.071225 × 100

= 7.1225%

Approximately to 2 decimal places = 7.12

Therefore, the annual effective yield = 7.12
