The slope is the difference of the y-coordinates divided by the difference of the x-coordinates, which gives us 5/2, or 2.5
To find x we are gonna use the cosine formula.
Cos 0 = adj/hyp
0 represents theta
Cos 0 = adj/hyp
Cos 0 = 25/40
Convert 25/40 to decimal from
25/40 = 0.625
On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.
Cos-1 0 0.625
= 51.31 degrees
x is therefore 51.3 degrees to the nearest tenth
The answer is 12 and 4 because 4 times 2 is 8 and if you add that by four more that would equal 12 the same amount as the first nubmer
Answer:
(5, 2) & (-4, -9)
Step-by-step explanation:
Use the vertex form, y = a(x − h)² + k, to determine the values of a, h, and k
(h, k) = (5, 2)
(h, k) = (-4, -9)

Well, you will start with the stickers. 5 * 25 = 125, so she will have 125 stickers. Next, she will have 3 boxes of markers, with 12 in each, so she will have 26 markers. If she gets 8 stickers from a friend, she will have 125 + 8 = 133. She will have the same number of markers still.
