Answer: x=2
Step-by-step explanation:
Given
9(x+1)=25+x
Distributive property
9x+9=25+x
Subtract x on both sides
9x+9-x=25+x-x
8x+9=25
Subtract 9 on both sides
8x+9-9=25-9
8x=16
Divide 8 on both sides
8/8 x=16/8
x=2
Hope this helps!! :)
Please let me know if you have any question
the correct domain oh h is C
#1 is A and #2 is 24 I think
Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
Using elimination, you can do
4x+3y-(4x-2y)=3-(18)
5y=-15
y=-3
Substitute it back into original equation:
4x+6=18
4x=12
x=3
<h2>
So, the answer is <u><em>
x=3, y=-3</em></u></h2>
