Answer:
X= 5
Step-by-step explanation:
1/2x -3 = 7
first you + 3 to both sides to get the x by it's self on one side of the (=)
Why +3 and not -3? because if you add 3 to the -3 on that side it goes to 0 witch means there is nothing there!
1/2x= 10
now you (/) by 2
10/2 =5
x=5
The answer is b because every hour he is making the same amount of money.
We can first find the probability of the first person picking Brand A, which would be:
9/6+9
=9/15
=3/5
We can then find the probability of the second person choosing brand A:
(9-1)/(6+9-1)
=8/14
To find the probability they both select Brand A, we could multiply them together:
3/5 x 8/14
=12/35
Therefore the answer would be 12/35.
Hope it helps!
B: 5(x+4)^2 Explanation: The “5” at the beginning of the equation represents stretch by five (multiplying the 1, 3, 5 rule, therefore making it over one up five, over one up fifteen, etc.) the +4 represents moving right 4 times.
