Answer:110
Step-by-step explanation:x^2+17x=15x+35
x^2+17x-15x-35=0
x^2+2x-35=0
delta=2^2-4*1*(-35)=4+140=144
x1=(-2+V144)/2=(-2+12)/2=10/2
x=5
so 15*5+35=75+35=110
Answer:
-A
Step-by-step explanation:
Additive inverse is just changing the sign of the number and adding it to the original number
Answer:
Dividing with negatives will result in a flip in the signs.
Step-by-step explanation:
In the first equation, -7y>161, if you solve it, you will need to divide both sides by -7.
Since you are involving a negative, you will have to switch the signs. That means that if you have solved this, the answer would be:
<h3>y < -23</h3>
Notice the change in signs.
---------------------------
Now in the second equation, the constant (161) is negative. So if you solve this,
You will only need to divide both sides by 7, which is a positive number. That leaves the sign to stay the same, so the answer would be:
<h3>y > -23</h3><h3>-----------------------</h3><h3>If you look at the signs in both answers, they are flipped.</h3><h3 /><h3 /><h2>Have a nice day!</h2>
