Answer:
-4/5.
Step-by-step explanation: You just need to do 4/5 times -1/1 and anything you multiply by one, the result is the number that was multiplied by 1. Since there is a negative in front of 1, the answer is -4/5.
Answer:
F(x) = -12/25x^2 +24x -268
Step-by-step explanation:
Eliminate parentheses and collect terms.
F(x) = -12/25(x^2 -50x +625) +32
F(x) = -12/25x^2 +24x -268
That's a 2/6 probability, so 1/3 -- B.
Answer:
1 no
2 I don't know
3 no
4 yes
5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept
Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
