Answer:
y=-3/7x+3
Step-by-step explanation:
A(0;3) B(7;0)
(y-yA)/(yB-yA)= (x-xA)/(xB-xA)
y-3/-3= x/7
7y-21=-3x
A
First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’
A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form
C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.
Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.
Line A has a different slope vs line 1, so they will eventually intersect only once
Hey there!
Sorry If this answer is late, but here ya go.
To find the radius of this Brazilian coin, first multiply 3.14 by 2. This will give you and answer of 6.28. Then, divide 84.78 mm by this, and you will get your radius of 13.5.
Have a good day! And stay CRAZZZY! :D
So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.
The sequence is geometric. The infinite series does converge.
Note how dividing any given term by the previous one leads to the same result
-8/12 = -2/3
(16/3) divided by -8 = -2/3
and so on...
So the common ratio is r = -2/3. This proves the sequence is geometric.
Since |r| < 1 is true, this means the infinite series converges to some fixed number.<span />
