<span>4x + 8y = 7
8y = -4x + 7
y = -1/2x + 7/8 this equation has slope = -1/2
</span><span>line perpendicular to the line 4x + 8y = 7, so the slope = 2
</span><span>same y -intercept as −3x + 5y = −2
</span><span> y intercept means x = 0
</span> 5y = −2
y = -2/5
so
b = -2/5
answer:
equation:
y = 2x - 2/5
The average atomic mass is 6.92X
How do we compute the average atomic mass?
In a bid to calculate the average atomic mass, we multiply the fraction of each isotope by the mass number , then add them together.
This is more like weighted average, as shown below:
average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)
average atomic mass=(6X*7.59%)+(7X*92.41%)
average atomic mass= 6.92X

Answer:
well then you fail and thats that
Step-by-step explanation:
Answer:
<u>Option B. Side YZ is the same length as side Y'X'.</u>
Step-by-step explanation:
At first the image is for the given question
The true graph is the attached figure.
As shown at the attached figure.
XYZ is reflected across the y-axis and then translated down 6 units to form X'Y'Z'.
So, X' is the image of point X
Y' is the image of point Y
Z' is the image of point Z
And ΔXYZ ≅ ΔX'YΔ'Z'
And the corresponding length are congruent.
We will check the options:
A. X has the same measure as X'. ⇒ True
B. Side YZ is the same length as side Y'X'. ⇒ Wrong
Because YZ will be translated to Y'Z'
C. Z has the same measure as Z'. ⇒ True
D. Side XZ is the same length as side X'Z'. ⇒ True
<u>So, The answer is option B. Side YZ is the same length as side Y'X'.</u>
X-X^2/ (x-3)^2 try that I’m not 100% sure tho
