Answer: y=(-3x+7)/2
Isolate y.
2y= -3x+7
y= (-3+7)/2
Answer: x=(-2y+7)/3
Isolate x
3x=-2y+7
x=(-2y+7)/3
Answer: 6x+4y=14
Idk if that counts but multiply the whole equation by 2.
Answer:
11.5 kg
Step-by-step explanation:
Is means equals and of means multiply
50% * 23 = W
Change to decimal form
.50 * 23 =W
11.5 = W
Answer:
1. distributive
2. associative
Step-by-step explanation:
In the first one, they are distributing 16 + 23 by the 4.
Therefore it is distributive property as they are splitting and then separately multiplying.
In the second one, the parentheses are shifted. The shifting of parentheses indicates priority, and the associative property says in addition you can choose what you'd like to do first and it won't change the answer.
Answer:
Graph = Cardioid
Axis of symmetry = y-axis
Critical points= 
Step-by-step explanation:
General equation for this type of cardioid is:
a ± b sinθ
Condition for a cardioid = 
Axis of symmerty according to the graph of 2 + 2 sinθ is along y-axis.
Critical points:
r = 2 + 2 sinθ ⇒ r = 2(1 + sinθ) ⇒ r' = 2 cosθ
∵derivative of 1 + sinθ = cosθ
For finding critical point the derivative is equal to zero,
2 cosθ = 0 ⇒ cosθ = 0
the value of cosθ is equal to zero at intervals:
So, critical points =
