Step-by-step explanation:
We just have to remember the line equation <u>y=mx+b</u>
, then place the given equation into this form (y= -3x-6).
Remember that (m) is your slope. So, to find a parallel line, they must have an equal slope. Check the other equations and see which one had a slope of -3. The answer C also has a slope of -3. So those lines would be parallel.
First of all, it's not pie. It's pi.
Now, the problem.
Radius is always 1/2 x d (d meaning diameter)
That gives us 5.
The formula is 3.14 x 5^2(h/3)
If you solve it from left to right, you get 130.83
Answer:
Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
Explanation:
Marks received by Marta in four tests = 86, 84, 97 and 89
Let mark received in fifth test be x
We have average of five test is more than or equal to 90
So we have
So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
Answer: 2 real zeros
discriminant: b^2 - 4ac
a = 3, b = -7, and c = 4
so, (-7)^2 - 4(3)(4) = 1
Since the discriminant is positive, there are 2 real zeros, if the discriminant was negative there would be 2 complex zeros, and if the discriminant equaled 0 then there is one real answer
