Answer:
the first answer ( I think these are 3 different questions) is y = -4x + 7
the second answer is y = -3x + 5
the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.
Answer:
5 + (-5) and 8 + (-8)
Step-by-step explanation:
Sum of zero means when you add them you get 0
so the others are wrong
-5 + (-5) = -10 because you have -5 and you add another -5
-12 + (-12) = -24 you start with -12 and you add another -12
Think of positive and negative numbers like floors in a building. Positive numbers are the stories and the negative numbers are the basement and sub-basement, zero is the ground level. So for 5 + (-5) you go up 5 floors, then you go down 5 floors. you end up on the ground level, 0.
Y = x + 6
y has to be greater than or equal to 6
x has to be greater than or equal to 0
3/5 of 15=n
n=9
So, if you divide 3/5 of 15, you get 9 as your answer.
<span>Since y=4, when x=-2, plug it into the formula above, and you have
y=kx
4=k(-2)
Solve for k, k=-2
</span><span>Now, y = -2x, so if x=30</span>y=-2*30=-60.
