Answer:
Step-by-step explanation:
Slope = 2 and passes point (4,7)
The equation is y - y1 = m(x - x1)
And y1 = 7 while x1 = 4, m = 2
: - y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 8 + 7
y = 2x - 1 this is the equation

Hello, remember you need to write complete questions in order to get good and exact answers. Here you haven't provided any fractions, so I'll give you my own fractions.
The first fraction is:

The second fraction is:

So let's say that difference is:

Therefore, the result is:

The representation of this problem is shown using the number line below. As you can see, we have written both 1/2 and 1/4 and the difference is also indicated giving the result 1/4. That is, if we walk from 1/4 to 1/2 we'll walk 1/4 units.
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
Answer:
Step-by-step explanation:
Because you can't do -x+1 so it would be (1,0) and then you have x^2 +3x-4 which is (-5,6)
Step-by-step explanation:
Slope of line ST = Slope of line PQ = -3.
y = -3x + c
When x = 3, y = -1
=> (-1) = -3(3) + c, c = 8
Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.
