3y > 2x + 1
You have asked us to check out the point where x=4 and y=3 .
All we need to do is to plug those numbers in place of 'x' and 'y',
and see whether the resulting statement is true:
3y > 2x + 1
3(3) > 2(4) + 1
On the left side, 3(3) is the same as 9.
On the right side, 2(4) + 1 is the same as (8 + 1) and that's 9 .
So the statement says: 9 > 9 , and that's <em><u>not</u></em> true.
9 is <u>equal</u> to 9, it is not <u>greater</u> than 9 .
So this point is not a solution of the inequality.
Answer:
Part 1) The commission is $35.6 and the total salary for week 1 is $285.6
Part 2) The commission is $45.04 and the total salary for week 2 is $295.04
Part 3) The commission is $39 and the total salary for week 3 is $289
Part 4) The commission is $32.96 and the total salary for week 4 is $282.96
Step-by-step explanation:
Let
x-----> the amount in sales
y----> Cindy Nelson’s salary
we know that
4%=4/100=0.04
so
The linear equation that represent this situation is
y=250+0.04x
case 1) week 1
Sales $890
For x=890
substitute in the linear equation
y=250+0.04(890)
y=250+35.6=$285.6
therefore
The commission is $35.6
The total salary for week 1 is $285.6
case 2) week 2
Sales $1,126
For x=1,126
substitute in the linear equation
y=250+0.04(1,126)
y=250+45.04=$295.04
therefore
The commission is $45.04
The total salary for week 1 is $295.04
case 3) week 3
Sales $975
For x=975
substitute in the linear equation
y=250+0.04(975)
y=250+39=$289
therefore
The commission is $39
The total salary for week 1 is $289
case 4) week 4
Sales $824
For x=824
substitute in the linear equation
y=250+0.04(824)
y=250+32.96=$282.96
therefore
The commission is $32.96
The total salary for week 1 is $282.96
Agora, só por curiosidade, veja como "n" poderá ser zero ou três.
Answer:
<h2>Surface area = 373.66</h2><h2>
Step-by-step explanation:</h2>
![T.S.A = \pi r(r+l)\\l = 10mm\\r = 7mm\\\\T.S.A = 3.14 \times 7(7 + 10)\\= 21.98(17)\\T.S.A = 373.66\\\\T.S.A = 373.66](https://tex.z-dn.net/?f=T.S.A%20%3D%20%5Cpi%20r%28r%2Bl%29%5C%5Cl%20%3D%2010mm%5C%5Cr%20%3D%207mm%5C%5C%5C%5CT.S.A%20%3D%203.14%20%5Ctimes%207%287%20%2B%2010%29%5C%5C%3D%2021.98%2817%29%5C%5CT.S.A%20%3D%20373.66%5C%5C%5C%5CT.S.A%20%3D%20%20373.66)
Think of the tens and the units separately:
16 x 34
= (10 + 6)(30 + 4)
Then we can distribute and get:
10(30 + 4) + 6(30 + 4)
And then further to get:
(10 x 30) + (10 x 4) + (6 x 30) + (6 x 4)
Each of these multiplications is easy enough to do in your head:
300 + 40 + 180 + 24
Add up the results:
300
180
