Answer:
7(3a + 5)
Step-by-step explanation:
Rewrite 21 as 7 · 3
Rewrite 35 as 7 · 5
Therefore,
⇒ 21a + 35 = 7 · 3a + 7 · 5
Factor out common term 7:
⇒ 7 · 3a + 7 · 5 = 7(3a + 5)
Answer:
c= (f-d)/ab
Step-by-step explanation:
- abc+d = f
- Subtract f from both sides so abc= f-d
- Divide by ab from both sides so c = (f-d)/ab
Answer:
9) Domain: 0≤x≤6
Range: -3≤y≤3
10) Domain: -∞≤x≤∞
Range: -∞≤y≤∞
11) Domain: -∞≤x≤∞
Range: y≥-2
13) Domain: -∞≤x≤∞
Range: -2≤y≤4
Step-by-step explanation:
9) Domain: 0≤x≤6
Range: -3≤y≤3
10) Domain: -∞<x<∞
Range: -∞<y<∞
11) Domain: -∞<x<∞
Range: y≥-2
13) I think you need to look at this one again. It looks like:
Domain: -∞<x<∞
Range: -2≤y≤4
I think the first one might be 18 second might be 10
