Answer:
y = -4/5x - 4
Step-by-step explanation:
y - y1 = m(x-x1)
4x + 5y = 20 ( subtract 4x on both sides)
5y = -4x + 20 (divide by 5 on each side)
y = -4/5x + 4
So we know one point is (0,4) y-intercept
now plug in (0,4)
y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)
y - 4 = -4/5x (now add 4 on each side)
y = -4/5x - 4
Answer:
2x is your slope and -8 is your y intercept
Step-by-step explanation:
The z-score is the number of standard deviations from the mean. For a given x-value, mean (μ), and standard deviation (σ) the z-score is given by
... z = (x -μ)/σ
(a) x=196, μ = 180, σ = 8 gives a z-score of
... z = (196 -180)/8 = 16/8
... z = 2.0
(b) The area associated with x=2 is 0.4772
(c) Rounded to the nearest thousandth, this is 0.477
(d) Carl's subtraction gives
... 0.50 - 0.477 = 2.3%
Hello,
Answer A (graph most left)
Intersection is (10/3,-11/3)
y=-2x+3
y=-2-x/2
so -2x+3=-2-x/2
==>3x/2=5 ==>x=10/3
and y=-2*10/3+3=-11/3
The correct answer is C.
Hope this helps
