Answer: $9x+y=-6$

Step-by-step explanation:

$Standard: Ax+By=C$

$y=-9x-6$

We need -9x on the left side, to move it, we must add 9x on both sides.

$9x+y=-9x-6+9x\\9x+y=-6$

Done. We have Ax = 9x, By = 1y and C after the equal sign = -6

Tess created a Pythagorean triple of (24, 32, 40) by multiplying the known Pythagorean triple 3, 4, and 5 by 8. Is Tess correct?

pentagon [3]

Answer:

(24, 32, 40) is a Pythagorean triplet.

Option A) Yes, as long as each number in the Pythagorean triple is multiplied by the same whole number.

Step-by-step explanation:

We are given the following in the question:

Pythagorean triplet: (3,4,5)

New Pythagorean triplet obtained = (24, 32, 40)

Pythagoras theorem:

For a right angles triangle the sum of square of sides of triangle is equal to the square of hypotenuse of triangle.

Verification:

$24^2 + 32^2\\=576 + 1024\\=1600\\=40^2$

Yes, Tessa is correct.

(24, 32, 40) is a Pythagorean triplet.

Pythagorean triple be created using multiplies of a known Pythagorean triple

Option A) Yes, as long as each number in the Pythagorean triple is multiplied by the same whole number.

Vance weighs 250 pounds and is losing 5 pounds each month. Phillip weighs 200 pounds

Lelu [443]

Answer:

250-5m=200+4m ; 5.56 months

Step-by-step explanation:

<u>Let's start this question by writing two expressions that depict the situation.</u>

Vance: 250-5m

This simply means that Vance currently weighs 250 pounds, and every month he is losing 5 pounds. (m=number of months)

Phillip: 200+4m

This is essentially the same thing. Phillips starting weight is 200, but here we use an addition sign because he is gaining 4 pounds every month as opposed to losing it.

To find the number of months it'll take for them to weigh the same, we just need to equate the values and solve for m.

<u>Our equation would then be:</u>

250-5m=200+4m

Let's solve the equation by bringing the variables to one side and the numbers to the other.

250-5m=200+4m

Subtract 4m from both sides

250-5m-4m=200+4m-4m

250-9m=200

Subtract 250 from both sides

250-250-9m=200-250

-9m=-50

Divide both sides by -9

m=5.556

So it will take about 5 months and a half to weigh the same.

A sample of 173 students using Method 1 produces a testing average of 88. A sample of 127 students using Method 2 produces a tes

Lerok [7]

Answer:

43 < μ₁ - μ₂ < 49

Step-by-step explanation:

Sample 1:

Mean x₁ = 88

Sample size n₁ = 173

Sample standard deviation s₁ = 12,22

Sample 2:

Mean x₂ = 53,5

Sample size n₂ = 127

Sample standard deviation s₂ = 13,59

CI 95 % α = 5% α = 0,05 α/2 = 0,025

We need to find:

( x₁ - x₂ ) - tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂) < μ₁ - μ₂ < ( x₁ - x₂ ) + tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂)

v = degree of fredom

v = [ ( s₁²/n₁ + s₂²/n₂)² / (s₁²/n₁)² /n₁-1 + (s₂²/n₂)²/n₂-1

v = [ (0,86 + 1,45 ) / 0,0043 + 0,017

v = 2,31 / 0,0213

v = 108

Then t 0,025, 108 from t table is: We will take v = 100

t = 1,984

Now

√ (s₁²/n₁ ) + (s₂²/n₂) = √ 0,86 + 1,43

√ 2,3 = 1,51

Then: CI:

(173 - 127 ) - 1,984*1,51 < μ₁ - μ₂ < ( 173 - 127 ) + 1,984*1,51

46 - 3 < μ₁ - μ₂ < 46 + 3

43 < μ₁ - μ₂ < 49
