First, subtract bh from both sides and cancel. Then, divide both sides by h and cancel. Finally, r= 25-bh/ h
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35
Divide
C=-5
Answer:
C. Ari and Matthew collide at 4.8 seconds.
Explanation:
Ari and Matthew will collide when they have the same x and y position. Since Ari's path is given by
x(t) = 36 + (1/6)t
y(t) = 24 + (1/8)t
And Matthew's path is given by
x(t) = 32 + (1/4)t
y(t) = 18 + (1/4)t
We need to make x(t) equal for both, so we need to solve the following equation
Ari's x(t) = Matthew's x(t)
36 + (1/6)t = 32 + (1/4)t
Solving for t, we get
36 + (1/6)t - (1/6)t = 32 + (1/4)t - (1/6)t
36 = 32 + (1/12)t
36 - 32 = 32 + (1/12)t - 32
4 = (1/12)t
12(4) = 12(1/12)t
48 = t
It means that after 48 tenths of seconds, Ari and Mattew have the same x-position. To know if they have the same y-position, we need to replace t = 48 on both equations for y(t)
Ari's y position
y(t) = 24 + (1/8)t
y(t) = 24 + (1/8)(48)
y(t) = 24 + 6
y(t) = 30
Matthew's y position
y(t) = 18 + (1/4)t
y(t) = 18 + (1/4)(48)
y(t) = 18 + 12
y(t) = 30
Therefore, at 48 tenths of a second, Ari and Mattew have the same x and y position. So, the answer is
C. Ari and Matthew collide at 4.8 seconds.
Solution:
we have been asked to sketch a plane containing points E, D and B.
where E and B are collinear with A. It mean all thses three points will fall on a straight line. Also D is a vertex where CD and FD meets.
The sketch has been attched below.
Here as you can see three points are in a staright line and we have another one in whuch two vectors CD and FD are meeting at the vertex D.
Answer:
x= 8/5 - 4/5y
Step-by-step explanation:
To get x independent we need to get everything else on the side x is on to the other side. We can start by adding 4y to the other side. We add because its negative and negative and positive cancel each other out.
-5x-4y=-8
add 4y
-5x= - 8 + 4y
Then to get the negative 5 to the other side we divide it to cancel it because it is multiplying right now.
-5x= - 8 + 4y
divide -5
x= - 8/-5 +4/-5y
in the fraction -8/-5 the negatives cancel out to get 8/5 and for 4/-5y we can more the negative to get us our final answer which is x=8/5-4/5y
