Option B:
Both n and m must be rational.
Solution:
Given information:
Sum of two numbers, n and m are rational.
<u>To find which statements are true:</u>
Option A: Both n and m may be rational but do not have to be.
It is not true because n and m given is rational.
It have to be rational.
Option B: Both n and m must be rational.
Yes, n and m must be rational then only the sum of numbers are rational.
It is true.
Option C: Both n and m must be irrational.
Sum of irrationals will be sometimes irrational and sometimes can't add.
So it is not true.
Option D: One number is rational and the other is irrational.
Rational and irrational cannot be add.
So it is not true.
Option B is true.
Both n and m must be rational.
Answer:
<h3>3×(-4) = y - 5</h3><h3>= ) -12 = y -5 </h3><h3>=) -12 +5 =y </h3><h3>=) -7 = y</h3>
<h2>y =-7</h2>
Answer:
y=6
Step-by-step explanation:
x=20
y=10
x=15 > 20x=15
x=15/20
x=3/5
y=10(3/5)
=6
5(2x-8)+15=-15 -15 in both sides
5(2x-8)=-30 /5
2x-8=-6 +8
2x=2 /2
x=1
I hope it helps
115 is the slope, and 5 is the y intercept. They tried tricking you by making x turn into m so you think you don't know the slope
