Answer: No
Step-by-step explanation: No, because a proportional relationship is a line that goes up at a constant rate, and goes through the origin, an example of a proportional relationship is a straight line starting from the origin ( or what we call the starting point)
Answer: B
Step-by-step explanation:
so for the slope to be parallel, it means it's the same slope as the given equation which is -5
using point slope, we can write a new equation
y -5 = -5(x+3)
y -5 = -5x-15
y = -5x-10
Answer:
The end result is -1/(x + 1)
Step-by-step explanation:
In order to find the answer to this, we first need to factor the denominator. Since it is a quadratic, we try to find number that multiply to the last term (8) and add to the middle term (9). In this case, the numbers 8 and 1 would work. This allows us to use those numbers in parenthesis along with x as a fully factored form.
x^2 + 9x + 8 = (x + 1)(x + 8)
Now that we have this factored we can take the original equation and factor a -1 out of the top.
(-1)(x + 8)/(x + 1)(x + 8)
Since there is an (x + 8) on the top and bottom, we can cancel those.
-1/(x + 1)
Answer:
9y-y-7y+3= y+3
Step-by-step explanation:
Any time there is no number in front of a variable, it's automatically 1, you just don't put the 1 there. So it would be
9y - 1y= 8y
So after you do that, you take the 7y and subtract it from 8y
8y - 7y= 1y
And remember you don't put the 1 so it simplifies to just y.
You simply add or subtract all the numbers with the same variable
