Answer:
k = 2/-3
Step-by-step explanation:
y = kx
Point: (-3, 2)
2 = k(-3)
k = 2/-3
k = -0.6
D.dilation changes the size is your answer. Hope this helps!
Answer:
x² + (y-74)² = 4900
Step-by-step explanation:
Circle equation: (x-h)² + (y-k)² = r²
"h" refers to horizontal shifts while "k" refers to vertical shifts. If the center of the wheel is directly above the origin of the rectangular plane and the entire wheel is 4 ft. from the ground then:
- h = 0
- k = 74 (the radius + 4 ft.)
- r = 70
So plugging those into the equation of circles, we get the answer above.
Answer:
, 9
Step-by-step explanation:
= 
÷ 
=
= 
= 9
In math, when you see the word "of" it usually means "times".
So the question is:
<u>2/3 times something = 10</u>
Multiply each side of the equation by 3 :
2 times something = 30
Divide each side by 2 :
<em> something = 15</em>
