Answer:
Slope = - 8
Step-by-step explanation:
Let,
x1 = 8
y1 = 36
x2 = 11
y2 = 12
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 12 - 36 ) / ( 11 - 8 )
= - 24 / 3
Slope = - 8
Step-by-step explanation:
I guess it means we need to calculate the height of the green dot on the bicycle wheel that moves as the wheel turns by a certain radial distance.
since the circumference of a circle is 2×pi×r, the circumference for a circle with radius = 1 is simply 2×pi (ft in this case).
pi/2 = 90° or a quarter rotation.
pi = 180° or a half rotation.
3×pi/2 = 270° or 3 quarter rotation.
2×pi = 360° or a full rotation.
the height starts at 6ft, and can go up 2 more ft (the diameter of the wheel) to 8 ft.
so, the table is
0 6
pi/2 7 (6+1)
pi 8 (6+2)
3×pi/2 7 (6+2-1)
2×pi 6 (6+2-2) back to the starting height
so,
a = 6
b = 7
c = 8
d = 7
e = 6
Hi there!
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.
Hope this helps!
A - variables
B - multiplied
C - reciprocal?
D - 0
//
I'm not too sure about C. it can either be the reciprocal or the opposite.
