Hello there!
Finding the solution will require us to write this down in numbers. Then after that, we will solve...
sqrt(x+2)+4=6
First let's move the 4 to the other side...
sqrt(x+2)=2
Now we need to square both sides so that we can get x out of the radical...
[sqrt(x+2)]²=2²
x+2=4
x=2
Now is this solution extraneous? We need to plug this BACK INTO the original equation and if we get a negative under a radical, we know it's extraneous. Also, if
sqrt(x+2)+4=6
sqrt(2+2)+4=6
sqrt(4)+4=6
2+4=6
Well it looks like we are correct! 2 is NOT an extraneous solution!
I hope this helps!
Best wishes :)
Answer:y<3/4x
Step-by-step explanation:
Its proportional
y intercept is 0 which means nothing
slope is 3/4
so
y<3/4x
BTW dotted lines are < not ≤
Answer:
Have you gotten the answer. if yes Hmu... Aihs I sit beside you
Step-by-step explanation:
Answer:
Joel rolls two fair number cubes at the same time.
Each cube has six sides 1, 2, 3, 4, 5, 6
=> There are 6 x 6 = 36 possible pairs (or 36 possible sums)
The collection of pairs that have sum less than 4 includes (1, 2), (2, 1) and (1, 1) => 3 cases (*)
The sum that is odd when two cubes show one odd number and one even number. Therefore each side of first cube has 3 options from second cube to form an odd sum. => The total number of cases: 6 x 3 = 18 cases
In these 18 cases, there are two cases (1, 2) and (2, 1) which have been counted already at (*) => Total case that the sum of the numbers will be odd or less than 4: T = 3 + 18 - 2 = 19 cases
=> Probability that the sum of the numbers will be odd or less than 4:
P = 19/36 = 0.53
Hope this helps!
