What is the slope intercept form of the line that passes through the following pints? (-4,5) (-2,-6)?

Answers

Answer:

y=-11/2x-6

Step-by-step explanation:

1. Find the slope of the line

Equation to find slope: y2-y1

x2-x1

6-5= -11

-2-(-4)=2

2. Put slope and one corrdinate pair into point slope form

Point Slope Form: y=m(x-x1)+y1

y=-11/2(x-(-4))+5

y=-11/2x-11+5

Answer:

y = 15∠abc = 68°∠bac = 78°∠acb = 34°

Step-by-step explanation:

It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:

  146° = (5y+3)° +(4y+8)°

  135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11

  15 = y . . . . . . . . . divide by 9

∠abc = (4y+8)° = (4·15 +8)° = 68°

∠bac = (5y+3)° = (5·15 +3)° = 78°

∠acb = 180° -146° = 34°

Alex and Carmen both sell items at craft fairs. Alex earns $36 for 3 birdhouses, and Carmen earns $75 for 5 scarves. What is the unit rate that each person earns for their craft? How many birdhouses will Alex need to sell in order to make as much as Carmen does when she sells 12 scarves? How do you know?

Answers

Answer:

To be able to find the unit rate that each person earns for their craft, you have to divide the amount each person earns by the number of units:

Alex: $36/3=$12 per unit

Carmen: $75/5=$15 per unit

To find the amount of birdhouses that Alex will need to sell in order to make as much as Carmen does when she sells 12 scarves, first you have to determine the amount that Carmen earns when she sells 12 scarves:

$15*12=$180

Now, you need to divide $180 by the price per unit Alex earns to find the amount of birdhouses that he needs to sell:

$180/$12=15

This means that Alex needs to sell 15 birdhouses to make as much as Carmen does when she sells 12 scarves

Lin is interested in how many of her classmates watch her favorite TV show, so she starts asking around at lunch. She gets the following responses: 4 YES and 10 NO. If she ask one more random classmate, do you think they will say "YES" or " NO"?

Answers

Answer:

They will probably say NO

Step-by-step explanation:

Add to find the total number of response.

10 + 4 = 14

Find the probability of someone saying yes or no.

4 / 14 ≈ 0.29 or 29%

10 / 14 ≈ 0.71 or 71%

As you can see, saying NO is more likely than saying YES.

[tex]f(x) = 15x - 200[/tex]

Step-by-step explanation:

Given

[tex]Earnings = \$10[/tex] per hour for 40 hours, weekly

[tex]Additional\ Hour = \$15[/tex] per hour over 40 hours, weekly

Required

Determine f(x)

From the question, we have that

x represents hours worked

Earnings in 40 hours is: 40 * 10 = $400

Hours over 40 will be: x - 40

So, earnings during this time will be: (x - 40) * 15

Total earnings is:

[tex]f(x) = 400 + (x - 40) * 15[/tex]

[tex]f(x) = 400 + 15x - 600[/tex]

[tex]f(x) = 15x - 600 + 400[/tex]

[tex]f(x) = 15x - 200[/tex]

Answer:

The following points are on the line

(x,y) = (2,120)(x,y) = (3,180)(x,y) = (4,240)

There are other points on the line, but I'm focusing on the points where the three filled in circles are shown. I'm ignoring (0,0) because that point won't be useful for the next section below.

Pick any of the three points and divide y over x

y/x = 120/2 = 60y/x = 180/3 = 60y/x = 240/3 = 60

Whatever point you choose, you'll get the same ratio. The constant of proportionality is 60.

In the context of this problem, the 60 refers to the speed of the car.

The car travels 60 miles in 1 hour, or at a speed of 60 mph.
