Subtract 3 to get:
7k^2-6k=0
Clearly, we can factor out a k to find that:
k(7k-6)=0
If either k or 7k-6 is zero, the whole expression is zero, so our solutions are zero and 6/7.
Answer:
7+5x+9=−3x
7+5(-2)+9=−3(-2)
7+-10+9=6
-3+9=6
6=6
Step-by-step explanation:
7+5x+9=−3x
7+5(-2)+9=−3(-2)
7+-10+9=6
-3+9=6
6=6
Answer: 1/4:1 1/4 = 2:b
↓
1/4 / 5/4 = 2/b
4/4 * 5 = 2/b
1/5 = 2/b
b/5 = 2
b = 2 * 5
b = 10
Step-by-step explanation:
The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
