Answer:
10
Step-by-step explanation:
P.s. Coefficient always goes before the variable
= 2b + 4
= 2(3) + 4 Substitute b for 3
= 6 + 4
= 10
Answer:
(2,3,4,5)
Step-by-step explanation:
The domain are all real number at x-axis
So the answer is option b (2,3,4,5)
Answer:
1. y=5 x=8
2. x=9 y=5
3. x=12 z=4
Step-by-step explanation:
1. 4(5)+5(8)=60
2. 5(9)+3(5)=60
3. 4(12)+3(4)=60
Using distributive property, we get:
3x-9=0
3x=9
x=3
So, x=3. Now that was easy, huh? :)
