I'll do the first graph.
We can easily find the y intercept by inputting 0 for x.
y = -2(0) + 7
y = 7
The y-intercept is (0, 7)
To find the x intercept, isolate x.
y = -2x + 7
Add 2x to both sides.
2x + y = 7
Subtract y from both sides.
2x = -y + 7
Divide by 2 on both sides.
x = -1/2y + 3.5
Input 0 for y.
x = -1/2(0) + 3.5
x = 3.5
The x intercept is (3.5, 0)
Now try the rest own your own! :)
Answer:
the answer is B
Step-by-step explanation:
area of the minor arc is teter all over 360 times 2 pie r square.
that is

= but because the question said for length AB, youvhave to use only one radius.

You the use 40 to cancel 160 and 360 to get 4 all over 9 times 2 pie times 9.

You then cancel 9 with 9 to get 4 times 2 times pie

this is equal to

Answer:
Yes
Step-by-step explanation:
the angle c is 90°, it is a right triangle. (you see from the picture).
the sum of the interior angles are 180° (in all triangles)
so
180 - 90 - 29 =
61° (angle A)
----------------------
90 + 61 + 29 = 180°
