What is the approximate equation of this line of best fit in slope-intercept form?

y = −13x + 13 over 10
y = negative 13 over 10x + 13
y = negative 10 over 13x + 13
y = −13x + 10 over 13

Answers

Answer:

Step-by-step explanation:

y = negative 13 over 10x + 13 is the best choice. (0, 13) is the y-intercept. If we begin at (0, 13) and move approximately 10 units to the right, y decreases by 13, so the slope is m = -13/10.

Writing y = negative 13 over 10x + 13 as y = negative 13 over 10 plus 13 would be clearer. We must emphasize that the slope is -13/10 and that this should be enclosed in parentheses: y = (negative 13 over 10)x + 13.

A. 113 mm2

B. 75 mm2

C. 66 mm2

D. 207 mm2

Answers

Answer:

Step-by-step explanation:

A=πr(r+h2+r2)=π·3·(3+42+32)≈75.39822

Answer:

75.39 mm²≈ 75 mm²

Step-by-step explanation:

A=πrl+πr²

l=[tex]\sqrt{r^2+h^2}[/tex]

A=πr(r+[tex]\sqrt{r^2+h^2}[/tex])=π·3·(3+[tex]\sqrt{4^2+3^2}[/tex])≈75.39 mm²

75.39 mm² ≈ 75 m²

1) y = 1x + 95.50
x = number of bandanas

2) y = (1 • 50) + 95.50
$145.50 for 50 bandannas

3) 116.50 = 1x + 95.50
get x by itself

116.50 = 1x+ 95.50
-95.50 -95.50

21 = 1x
divide by 1
21 = x
you get 21 bandannas when you pay $116.50

Answer:

1. y=x+95.50

2. $145.5 (because 50 + 95.50)

3. 21 bandanas (because 116.5-95.5)

Answer:

I would say the answer is C: Find the perimeter of the painting; and

35 inches.

Step-by-step explanation:

Ok, I might be super-duper wrong, but please don't hate me!!!

I think the answer is C. because to know how much money you need, you need to find how much something costs.

It also asks for you to answer the first step, or find the perimeter.

Formula of perimeter = b2 + w2 (base times two plus the width times two).

6 1/4 * 2 = 12.5

11 1/4 * 2 = 22.5

12.5 + 22.5 = 35.

The two answers are C: Find the perimeter of the painting and

35 inches.

Brandon’s method is incorrect because if we continue the pattern, 9 times 1/2 is 4.5. It’s obvious that the square root of 9 is 3. Similarly, the square root of 16 is 4, but 16 times 1/2 is 8. Any number you will try after that won’t work.

To qualify for the postcard rate for postage, a postcard must be less than 4 1/4 inches high. Elayne has a postcard that is 4 7/8 inches high. How much is her postcard over the height limit?

Answers

Answer:

Step-by-step explanation:

s0 obasically yah

5/8 inches

The postcard must be less than 4 1/4 inches high.
Elayne's postcard is 4 7/8 inches high.
We need to subtract the limit from the height of her postcard to know how high it is above the limit:
4 7/8 - 4 1/4 = 5/8
Her postcard is higher than the limit by 5/8 inches.

The circle is open if the inequality is greater than (>) or less than (<) and closed if the inequality is greater than or equal to (≥) or less than or equal to (≤)
If the arrow points to the right (—>) towards bigger numbers, x (whatever number is on the line) will be GREATER (> or ≥)
If the arrow o points to the left (<—) towards smaller numbers, x will be LESSER (< or ≤)

1. Starts at -2 with a closed circle and goes in the positive direction —>
So x ≥ -2
2. Starts at 2 with an open circle and goes in the negative direction <—
So x<2

And the rest use the same method.

Answer:

Green answers in order of 1-7 as green appears

Just show the ones at start of each answer in bold

1) x ≥ -2 closed circle start opp/s x ≤ 0 closed circle stop

2) x < -2 open circle stops opp/s x ≥ 0 closed circle start

3) x > 2 open circle starts opp/s x ≤ 0 closed circle stops

4) x ≤ 2 closed circle stops opp/s x ≥ 0 closed circle starts

5) x < 2 open circle stops opp/s x ≥-6 closed circle starts

6) x > 2 open circle starts opp/s x ≤ 6 closed circle stops

7) x < -2 open circle stops opp/s x ≥ -6 closed circle starts

Step-by-step explanation:

Rule 1 closed circle is ≥ right open circle shows > right

Rule 2 closed circle is ≤ left open circle shows < left

Rule 3 with inequalities on line x > 2 means it starts from this value and moves right.

Rule 4 with inequalities on line x < 2 means it ends in this value.

Rule 5 Remember rule 3 and rule 4 for direction start and stop

remember rule 1+ rule 2 for choice of closed circle etc.

m = h/55
m = 55/h
m = 55h
