Answer:
In order of what is shown on the pic:
- Trinomial
- Monomial
- Trinomial
- Binomial
- Polynomial with four terms
Step-by-step explanation:
Again, in the same order as above:
1. The first has three terms, making it a trinomial
2. 7x^2 - 7x^2 +4x
The 7x^2 cancels out and we are left with only 4x
Since there is one value, it is a monomial
3. This one has three terms, making it a trinomial
4. This one has two terms, making it a binomial
5. The last one has four terms, making it a polynomial with four terms.
Answer:
B and D
Step-by-step explanation:
Equations with the same x- term on both sides will have no solution
A
4x - 13 = 5(x + 4) = 5x + 20
4x ≠ 5x
This equation has a solution
B
5(3 + 2x) = 10x + 4
15 + 10x = 10x + 4
10x on both sides ⇒ no solution
C
2(3 - 5x) = 8(x + 1)
6 - 10x = 8x + 8
- 10x ≠ 8x
This equation has a solution
D
9x - 6 = 3(3x - 2) = 9x - 6
9x on both sides ⇒ no solution
If y varies directly with x, then the ratio y/x will always be the same. Set it equal to the known values and solve for y.
y/x = -12/6
Cross multiply
6y = -12x
y = -2x
Answer:
0.200
Step-by-step explanation:
The probability of obtaining a 3, in one roll of a fair die is 1/6.
Now, we have 5 rolls.
We now want to know the probability of a 3 showing up in at least one of the rolls.
This simply mean, we add the probabilities of three showing one time plus probability of three showing in 2 of the rolls e.t.c
This means we can have 3 showing up to 5 times.
We add the probabilities as follows:
(1/6) + (1/6)^2 + (1/6)^3 + (1/6)^4 + (1/6)^5 = 0.199974 = 0.200
