Kazeer [188]3 years ago

Answer:

y = -5

Step-by-step explanation:

-3x +9y = -57

Let x = 4

-3*4 +9y = -57

-12 +9y = -57

Add 12 to each side

-12+12 +9y = -57+12

9y = -45

Divide each side by 9

9y/9 = -45/9

y = -5

Convert 3/11 to a decimal equivalent using long division. (Ex: 80-30 is what I need but I'm not sure.)
Virty [35]
.27 repeating....  you have to put three on the inside and 11 outside, so 11 goes into 3 zero times so put a zero at the top. Write a zero underneath and subtract     3-0 (obviously 3) and put a decimal point after the first three under the sign and the 0 above it.  Add a zero after the threes decimal, and carry it down to the bottom most 3 to have 30.  11 goes into 30 two times so write a 2 at the top. Subtract the 30-22 at the bottom and get 8. Add another 0 after the 3 ( so now 3.00) and carry it to the 8 (80). 11 goes in 7 times, 77. So 7 on top and 80-77= 3 below.  Add another zero to repeat process if necessary, but otherwise it repeats, just so you know ;) hope this helps

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>

A point T on a segment with endpoints D (1, 4) and F (7, 1) partitions the segment in a 3:1 ratio. Find T.
velikii [3]

Step-by-step explanation:

given,

x1= 1 , x2= 7 , m1= 3

y1= 4 , y2= 1 , m2= 1

x=?

y=?

using section formula

x= (m2.x1 + m1.x2)/m1 + m2

x= find yourself

y= (m2.y1 + m1.y2) / m1 + m2

y= find yourself

lily swims a 100-meter race. she swims the first half in 27.8 seconds. she swims the second half in 30.12 seconds. how long does
Luden [163]

we know that

1) Lily swims a 100-meter race

2) She swims the first half in 27.8 seconds

3) She swims the second half in 30.12 seconds

so

To find the total time to swim the whole race sum the time in the first half plus the time in second half

(27.8+30.12)=57.92\ seconds

therefore

<u>the answer is</u>

57.92\ seconds
