Answer:
1. y = -11/4; (-2, -11/4)
2. y = -1; (0, -1)
3. y = -1/8; (1, -1/8)
4. y = 0; (8/7, 0)
5. y = 3/4; (2, 3/4)
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Since 6 = 5r + 1, r = 1
As for s, if s is 2, then you can do
4 x 2 + 5 = 13 & 6 x 2 + 1 = 13
13 = 13
So B!
Hope that helps!
Answer:
2.1
Step-by-step explanation:
You need to substitute the 11 for the x.
y = -8.9(11) + 100
y = -97.9 + 100
y = 2.1
Answer:
no solution.
Step-by-step explanation:
given that, y = 3x-1
so,
in equation, 3x-y = 9
putting the value of y here,
3x-(3x-1) = 9
3x-3x+1 = 9
3x and 3x is cancelled.
hence, no solution
The appropriate formula is
... z = (x - μ)/σ
Solving for x gives
... x = μ + z·σ
Substituting the given values lets you find x:
... x = 50 + 1.5·10
... x = 65
