Answer:

x = 6

y = 7

a = 1/4

Step-by-step explanation:

Equation 1:

2(3x+2) = 2x + 28

6x + 4 = 2x + 28

4x = 24

x = 6

Equation 2:

5y+13 = -43-3y

8y = -56

y = -7

Equation 3:

8a + 8 = 16 - 24a

32a = 8

a = 1/4

Answer:

first equation=6

second equation=15

Third equation=

Step-by-step explanation:

2(3x+2)=2x+28

6x+4=2x+28

collect like terms

6x-2x=28-4

4x=24

Divide both sides by 4

4x/4=24/4

x=6

second equation

5y+13=43-3y

collect like terms

5y-3y=43-13

2y=30

Divide both sides by 2

2y/2=30/2

y=15

Third equation

4(2a+2)=8(2-3a)

8a+8=16-24a

collect like terms

8a+24a=16-8

32a=8

Divide both sides by 32

32a/32=8/32

a=1/4

Paha777 [63]

Answer:

1 and 3/7 hour

Step-by-step explanation:

Every hour they get 140 miles closer (100 + 40). So you divide 200 by 140 which gets you 1.42... or 1 and 3/7 of an hour.

Help! Algebra!!!
balandron [24]
Thet contradict each other, that's why both of them are incorrect.
<span>Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form. 

p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial 

This polynomial has a degree of at least 4. It therefore cannot be cubic. 

Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do. 

(x - 1)(x - 2)(x - 3) 

This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct. 

Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve. I hope this helps</span><span>
