Answer:
z=-1
Step-by-step explanation:
First combine the like terms: -4z-11z+2z-(-6z)=-4z-11z+2z+6z=-15z+8z=-7z
Then solve after combining like terms:
Answer:
the conversion rate to convert miles per hour to minutes per hour is 1 miles per hour = 60 minutes per mile
We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
Answer:
<h2>
(9, -4) no</h2><h2>
(8, 6) yes</h2><h2>
(-1, -3) no</h2><h2>
(-2, 8) no</h2>
Step-by-step explanation
<em>x=8 is a vertical line passing the x-axis at 8, thus the ordered pairs that would work all have a x-value of 8: </em>
<em>we can write it like: </em>
<em>(8, y)</em>
<em />
<em>the only ordered pair that fits in here is the second one, that is (8, 6) the rest don't</em>
<em>thus the answer is such:</em>
(9, -4) no
(8, 6) yes
(-1, -3) no
(-2, 8) no
