Answer:
10 4 for question one
Step-by-step explanation:
I don't have one I just know how and I did this
4x - 8y = 8
8y = 4x - 8
y = 1/2 x - 1
slope: 1/2
y-intercept:(0, -1)
Line perpendicular- negative reciprocal slope
y-(-1) = -2 (x-0) Hahaha I don't know what is the point slope form though hahaha not sure with this.
Answer:
A=36 square units
Step-by-step explanation:
Let the unknown number be 
.
Then the opposite of this unknown number will be 
.
It is given to us in the question that when this unknown number, is increased by 9, or in other words when 9 is added to this unknown number, , then this becomes 5 times it's opposite, which is .
Thus, from the given condition in the question, the equation we get is as:
We will solve this by isolating as:
Thus the required number is -1.5
