Answer:
x - 5y = 22
Step-by-step explanation:
Step 1: rewrite the equation of the given line in to slope-intercept form by solving for y
x = 5y - 9
-5y = -x - 9 (subtract 5y and x from both sides)
y = x/5 + 9/5 (divide both side by -5)
Step 2: Our line is parallel to this line, so it has the same slope, but a different y-intercept, so set up the equation...
y = x/5 + b
We are given a point (x, y) of (2, -4), so plug that in and solve for b.
-4 = 2/5 + b
-4 - 2/5 = b (subtract 2/5 from both sides to isolate b)
-20/5 - 2/5 = b
-22/5 = b (simplify)
So the equation of our line is y = x/5 - 22/5
Step 3: Standard form is ax + by = c, where a is a positive integer
subtract x/5 from both sides...
-x/5 + y = - 22/5
multiply by -5 so x becomes a positive integer
x - 5y = 22

Answer:
Of the 600 elephants that he observes in random places in the reserve, he counts 
elephants with broken tusks.
Step-by-step explanation:
Let x denotes number of elephants having broken tusks out of 600 elephants.
Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.
So,
Of the 1 elephants that he observes in random places in the reserve, he counts 
elephants with broken tusks.
Therefore,
Of the 600 elephants that he observes in random places in the reserve, he counts elephants with broken tusks.
Hey there! :)
Answer:
r = 105.
Step-by-step explanation:
In the quadratic formula, √r = 
Where a = 1, b = -9, and c = -6. Therefore:
√r = √(-9)² - 4(1)(-6)
√r = √81 -4(-6)
√r = √81 + 24
√r = √105
Therefore, r = 105.
Answer:
3,400,007
Step-by-step explanation:
three million= 3,000,000
four hundred thousand= 400,000
seven= 7
so:
three million, four hundred thousand, seven= 3,400,007
