|-9| means the absolute value of -9 which is 9
so we have 9 - 9 = 0 (answer)
Answer:
C) 60 ft
Step-by-step explanation:
From any dot in the graph you can figure out the speed.
Let's take the one at 2 minutes, because it is on a grid point.
That one tells us that in 2 minutes, the animal travels 40 feet.
That means in 1 minute, it travels half that, i.e., 20 feet.
So in 3 minutes it will travel 20*3=60 feet.
The value of Z would be 225°
<h3>What is the angle at a point?</h3>
The angle at a point are angles that add up to 360°
Thus, X + Y + Z = 360°
X = 20°
Y = 135°
Then, Z = 360° - X - Y
Z = 360° - 20° + 135°
Z = 360° - 155°
Z = 205°
Therefore, the value of Z is 205°

Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
Answer:
Option E 
Step-by-step explanation:
we have

we know that
For x> 5 both sides of the equation will be positive
Squared both sides



Subtract 4 both sides
