Let's first solve <span>7x+y=4 for y
Subtract 7x from both sides to accomplish this
</span><span>7x+y=4
</span><span>7x+y-7x=4-7x
y = -7x+4
This equation has a slope of -7. This is the same as -7/1
Flip the fraction to get -1/7 and then flip the sign from negative to positive to get +1/7 = 1/7
The slope of this unknown perpendicular line is going to be m = 1/7
We now use the point (3,7) to figure out the value of b
y = mx + b
y = (1/7)*x + b ... plug in the value of m found earlier
7 = (1/7)*3 + b ... plug in the given point; solve for b
7 = (3/7) + b
7-(3/7) = b
49/7 - 3/7 = b
b = 46/7
So the answer in y = mx+b form is
y = (1/7)x + 46/7
where
m = 1/7 is the slope
b = 46/7 is the y intercept</span>
Answer:
They are similar.
Step-by-step explanation:
They both have the same ratio.
Answer:
I got 278 5/8
Step-by-step explanation:
the question stated square inches which I referred
to as area. You multiply both rectangles than add them together. I may be wrong but I hope this gives you a lead! :)
Well, the square root of 82 is an irrational number, so
it can never be completely written with digits. As a
decimal, it goes on and on forever, and never ends.
As a fraction, it can't be written at all.
The square root of 82 is approximately 9.055 .
(That number is about 0.0043% too small, which is pretty close.)
