Answer:
Take 7.1-4.9=x
Step-by-step explanation:
Answer:
1) Add 3n to both sides
2) Subtract 5 from both sides
3) Divide both sides by 6
n=3
Step-by-step explanation:
3n+5=23-3n
+3n +3n
6n+5=23
-5 -5
6n=18
/6 /6
n=3
Answer: the "first" 1 is right
Step-by-step explanation:
X-intercept: y = 0
y-intercept: x = 0
3x + 4y = 0
x-intercept: subtitute y = 0
3x + 4 · 0 = 0
3x = 0
x = 0 → (0; 0)
y-intercept: subtitute x = 0
3 · 0 + 4y = 0
4y = 0
y = 0 → (0; 0)
