7 0

Hi

(x,y) = (3,6) ⇒ x=3 and y=6

x+y ≤ 9
3+6 ≤ 9
9 ≤ 9 ⇒ 9 is lower than or equal than 9? Yes, true, 9 = 9

Answer: (3,6) is a solution

If you would like to know if (3, 6) is a solution to the inequality x + y <= 9, you can calculate this using the following steps:

(3, 6) ... x = 3, y = 6
x + y <= 9
3 + 6 <= 9
9 <= 9

Result: (3, 6) is a solution to the inequality x + y <= 9.

Flauer [41]

Answer:

(a) seems to be the closest to being correct of these five statements.

Step-by-step explanation:

Let's go through the list of possible descriptors:

a) There are no outliers. This seems to be the response most likely to be correct.

b) The distribution is not skewed left. It's skewed right.

c) The center is not 44. From what I see, the center is 48.

d) This distribution is not bimodal; it does not have two peaks.

d) The spread is not 38 to 67; it's 29 to 67.

What is the slope intercept form of the equation 4x-8y=72

Masteriza [31]

Answer:

y = 1/2x - 9

General Formulas and Concepts:

Alg I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form: 4x - 8y = 72

Step 2: Find slope-intercept form

Subtract 4x on both sides: -8y = 72 - 4x
Divide both sides by -8: y = -9 + 1/2x
Rewrite: y = 1/2x - 9

Is y=x^3 a solution of the differential equation yy'=x^5+y

shepuryov [24]

No; we have $y=x^3\implies y'=3x^2$ . Substituting these into the DE gives

$3x^5=x^5+x^3$

which reduces to $x^3=0$ , true only for $x=0$ .

Angle J and angle M are base angles of an isosceles trapezoid JKLM. If angle J=20x+9 and angle M =14x+15, find angle K

anzhelika [568]

K or l will be 151 degrees.

j and m are equal to each other, giving you x=1, substitute this in to get j and m equal 29 degrees. k or L are opposite angles meaning they add up to 180 when added to j and m so j+l=180 or m+k=180

A box contains balls numbered 3 through 15.

Phantasy [73]

Answer: 6/13

Step-by-step explanation:

A box contains balls numbered 3 through 15. This means that the sample space = {3 , 4 ,5 , 6 ,7, 8, 9, 10, 11, 12, 13, 14, 15,}

The total number of sample space = 13

Therefore : the probability of picking 3, 5, 9, 11, 12, 15 , will be the total number of times they appear in the sample space divided by the number of sample space.

number of times 3 appears = 1

number of times 5 appear = 1

number of times 9 appear = 1

number of times 11 appear = 1

number of times 12 appear = 1

number of times 15 appear = 1

All together , they appeared 6 times

Therefore : the probability of picking one of the numbers = 6/13
