what is 9x+15y=45 in slope intercept form

Answers

Answer 1
Slope intercept: y = mx + b
Subtract 9x from both sides
15y = -9x + 45
Divide by 15
Solution: y = -9/15x + 3
Answer 2

Answer:

y= - 3/5 x+3

Step-by-step explanation:

-\frac{3}{5}x+3:\quad -\frac{5x-15}{3}

I know that looks like it makes no sence but im pretty sure your answer is

y= - 3/5 x+3  or m= - 3/5

i have to find the mean and range of this data set and show work.
data set: 49,50,52,58,61,63,66,67,67,68

Answers

Answer:

61 is the mean and the range is 19

Step-by-step explanation:

trust

Mean = [tex]60.1[/tex] and Range = [tex]19[/tex]  for the given set of data.

What is Mean?

"Mean is the average set of all the given values."

What is Range?

"Range is the difference between highest and the lowest value."

Formula

Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]

Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]

                            = [tex]\frac{601}{10}[/tex]

                            = [tex]60.1[/tex]

Range = Max (x) - Min (x)

            =  [tex]68 - 49[/tex]

            = [tex]19[/tex]

Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and proposes two methods for collecting data. Method 1: As golfers approach the first tee, give some golfers wrist bracelets with magnets and some golfers wrist bracelets without magnets. During the round of golf, keep track of the length of the golfers’ shots. Method 2: Contact golfers who have purchased wrist bracelets with magnets and ask them to provide information about their shot length. Which statement about these methods is true? Method 1 is an observational study because it does not attempt to influence responses. Method 2 is an observational study because it does not attempt to influence responses. Method 2 is an observational study because it could include golfers from many golf courses. Both methods are observational studies because they both collect information about shot length.

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21

Answers

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

Find the measure of angle A

Answers

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

[tex]m\angle A = (x +53)\degree \\\\

4+3(x+2)=12
Plz answer ​

Answers

Answer: x = 2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

4+3(x+2)=12

Step 1: Simplify both sides of the equation.

4+3(x+2)=12

4+(3)(x)+(3)(2)=12(Distribute)

4+3x+6=12

(3x)+(4+6)=12(Combine Like Terms)

3x+10=12

3x+10=12

Step 2: Subtract 10 from both sides.

3x+10−10=12−10

3x=2

Step 3: Divide both sides by 3.

3x/3 = 2/3

ANSWER: x = 2/3
