Because thats not how its pronounced anymore.
Happy studying ^_^
Answer:
multiply the first equation by -2, then add them
Step-by-step explanation:
7x+4y=-4 *-2 7x+4y=-4 *-2 = -14x-8y=8
5x+8y=28
-14x-8y=8 x=-4, y=6
-9x=36
x=-4
7(-4)+4y=-4
-28+4y=-4
4y=24
y=6
<u>Answer</u>
y - 6 = -14/11(x + 4)
<u>Explanation</u>
slope = (change in y)/ (change in x)
= (6 - -8) / (-4 - 7)
= 14/-11
= -14/11
Equation
-14/11 = y - 6)/(x - -4)
-14/11 = (y - 6)/(x + 4)
-14(x + 4) = 11(y - 6)
y - 6 = -14/11(x + 4)
The answer is the third one.
The simplified expression will be 16+5f because in the parentheses you add 4 and f, f has an invisible one to it so 1 plus 4 equals 5 and f, 16+5f is your expression, but the answer is 21f, expression is 16+5f and answer is 21f
