what is y equal to 2x + 4y = -18

Answers

Answer 1
Answer:    y = (-1/2)x - 9/2

Slope = -1/2

Y intercept = -9/2

=====================================================

Work Shown:

2x + 4y = -18

2(x+2y) = -18 .... factor out 2

x+2y = -18/2 .... divide both sides by 2

x+2y = -9

2y = -9-x .... subtract x from both sides

2y = -x-9

y = (-x-9)/2 ... divide both sides by 2

y = (-x/2) - (9/2) ... break up the fraction

y = (-1/2)x - 9/2

The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.

Answer 2

Answer:

Step-by-step explanation:

2x + 4y = -18

2(x+2y) = -18 .... factor out 2

x+2y = -18/2 .... divide both sides by 2

x+2y = -9

2y = -9-x .... subtract x from both sides

2y = -x-9

y = (-x-9)/2 ... divide both sides by 2

y = (-x/2) - (9/2) ... break up the fraction

y = (-1/2)x - 9/2

The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.

1) Vitaminlerin özellikleri nelerdir?


2)Buldukları besinler nelerdir?


3)İnsanların beslenmesindeki önemi nedir?

Answers

Answer:

1.

Bazı vitaminler yağda çözünür; diğerleri suda çözünür. Suda çözünen vitaminler (C, tiamin, riboflavin, piridoksin, biotin, pantotenik asit, folat, B12) bir veya daha fazla polar veya iyonize edilebilir gruba sahip olma eğilimindeyken, yağda çözünen vitaminler (A, D, E ve K) ağırlıklı olarak aromatik ve alifatik karakterlere sahiptir.

2.

Besinler, yaşam ve sağlık için gerekli olan gıdalardaki bileşiklerdir ve bize enerji, onarım ve büyüme için yapı taşları ve kimyasal süreçleri düzenlemek için gerekli maddeler sağlar. Altı ana besin maddesi vardır: Karbonhidratlar (CHO), Lipitler (yağlar), Proteinler, Vitaminler, Mineraller, Su.

3.

Vitaminlerin farklı görevleri vardır - enfeksiyonlara direnmenize, sinirlerinizi sağlıklı tutmanıza ve vücudunuzun gıdalardan veya kanınızdan düzgün pıhtılaşmak için enerji almasına yardımcı olur. Beslenme Yönergelerini takip ederek, bu vitaminlerin çoğunu yiyeceklerden yeterince alacaksınız. Mineraller ayrıca vücudunuzun çalışmasına yardımcı olur.

Step-by-step explanation:

Given that:

Larger square is a dilation of smaller square

Dimension of smaller square (5 - 3) units by (5 - 3) units = 2 by 2

Dimension of larger square (7 - 1) units by (7 - 1) units = 6 by 6

Hence, the scale factor used to create the larger square from the smaller square will be:

Scale factor (x) * side of smaller square = side of larger square

x * 2 = 6

2x = 6

x = 6/2

x = 3

Hence, scale factor used to generate larger square is 3

Your brother traveled 117 miles in 2.25 hours to come home for Christmas. What's the average speed that he was traveling?

Answers

Answer:

52 miles per hour

Step-by-step explanation:

The formula for Average speed is given as: Distance(miles)/Time in hours

From the question,

Distance = 117 miles

Time = 2.25 hours

Average Speed = 117 miles/2.25 hours

Average Speed = 52 miles per hour

The average speed that he was traveling is 52 miles per hour

Step-by-step explanation:

The value of tan 60° in the triangle ABC is √3

Right angle triangle:

Right angle triangle have one of its angles as 90 degrees. The sides are called hypotenuse, adjacent and opposite side base on the angles.

Therefore,

ΔABC

∠C = 90°

AB = 12

BC = 6

∠B = 60°

∠A = 30°

Therefore,

tan 60° = opposite / adjacent

AC = √12² - 6² = √108 = 6√3

tan 60° = AC / BC

tan 60° = 6√3 / 6

tan 60° = √3

A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maximum area of the enclosure

Answers

Answer:

The answer is below

Step-by-step explanation:

A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure

Solution:

The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:

V'(x) = 0

V(x) = x(1500 - x) = length * breadth.

This means the enclosure has a length of x and a width of 1500 - x

Given that:

v(x)=1500x-x². Hence:

V'(x) = 1500 -2x

V'(x) = 0

1500 -2x = 0

2x = 1500

x = 1500 / 2

x = 750 feet

The maximum area = 1500(750) - 750² = 562500

The maximum area = 562500 feet²

Answer:

562500 feet²
