Answer:
To find the slope of this equation you want to put it into y=mx+b form
So in 5y=-x+2, you need to get the y by itself
Divide both sides by 5
y=-1/5x+2/5,
Slope equals -1/5x
Hope this helps ;)
Answer:
Step-by-step explanation:
If we are finding a line parallel to the given one, we need to use the same slope. That is, our new line should have a form like:
We can determine the value of "b" by using the condition that we want the line to go through the point (-4,5), therefore when x=-4, the y value for that line should be 5. In mathematical terms:
Therefore our new line parallel to the given one is:
G(f(2)) means work out whatever f(2) is then plug this into g(x).
So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.
So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.
So g(f(2)) = 10
Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)
B= 19ft
The height is 4 and the are is 76 and equal to 19ft
