Step-by-step explanation:</h2>
First of all, we need to plot the equation:
The graph of this equation is a parabola. The vertex of this parabola lies on the point (0, 1) and the x-intecepts are the points (-1, 0) and (1, 0). But the problem asks for the graph of<em> y greater than or equal to -x^2 + 1, </em>that is, the inequality:
To find this, we choose a point on the Cartesian plane, say, (0, 0) and let's take a look to the inequality:
So the region does't contain point (0, 0), therefore the graph is the one shown below.

============================================
Explanation:
The general form of a slope intercept equation is y = mx+b
m = slope
b = y intercept
Something like y = (-7/6)x + 1 matches with y = mx+b such that m = -7/6 is the slope and b = 1 is the y intercept. So that's why problem 1 matches with choice b (in column B).
Similar situations apply for problems 2 and 3
-----------
For problem 4, we can see the slope is m = -1, but unfortunately m = -1 isn't listed in column B. However, m = -7/7 is listed. So this is why problem 4 matches with choice a. This leaves problem 5 to match with choice e.
note: 6/7 = 12/14 after multiplying top and bottom by 2.

Answer:
c:8
Step-by-step explanation:
10/25 = r/20
25r = 200
25 25
r = 8
Basically a proportion so it’d be 1in/300 mi = 3in/x mi
cross multiple that out and you get 300•3=x and then just solve for x. the answer should be 900 miles.
