Lets reorder the equations

y = x - 1 (1)
y = x +1 (2)

Since both lines have the same slope (m = 1), then this is an inconsistent system with NO solution

Answer:

See the explanation

Step-by-step explanation:

Given function

$Y=3x+1$

We need to find $y$ value corresponding to each $x$ value.

So, plug each $x$ value in equation we get,

$plug\ x=4\\y=3(4)+1\\y=12+1\\y=13\\\\plug\ x=6\\y=3(6)+1\\y=18+1\\y=19\\\\plug\ x=10\\y=3(10)+1\\y=30+1\\y=31$

Now in next part of question it ask us to check each ordered pair.

Let us plug each $x$ value and $y$ value in the function $y=-3x-5$

$plug\ (1,-8)\\-8=-3(1)-5\\-8=-3-5\\-8=-8\\\\plug(-5,0)\\0=-3(-5)-5\\0=15-5\\0\neq10\\\\plug\ (-2,1)\\1=-3(-2)-5\\1=6-5\\1=1\\\\plug\ (-1,-2)\\-2=-3(-1)-5\\-2=3-5\\-2=-2\\$

we can see ordered pair $(1,8),(-2,1)and(-1,-2)$ true for function $y=-3x-5$

CaHeK987 [17]

Answer:

8.317 x 10^6 = 8,317,000

Step-by-step explanation:

You move the decimal over 6 places to the right because it's a positive number. If it were 10^-6 you would move the decimal over 6 places to the left.

A spinner is broken into section labeled 1 to 38. What is the probability that.On your next spin, that you will spin a 1?

VashaNatasha [74]

Answer:

1/38

Step-by-step explanation:

Given :

Probability = required outcome / Total possible outcomes

Total possible outcomes = total Numbe rod sections = 38

Required outcome = number of 1's on the entire section = 1

Hence, the probability of spinning a one equals :

P(spinning a 1) = 1 / 38
