Answer:what happened to c and a
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
1. Add like terms: 5x+7=27
2. Use the subtraction property on both sides to get rid of 7: 5x=20
3. Divide 5 on both sides to get x by itself: x=4
Answer:
y = (3 houses/month) x
Step-by-step explanation:
Let "x" represent the number of months Patty paints houses and "y" represent the number of houses Patty paints. We can represent the relationship between "x" and "y" using a linear equation, which has the following general expression.
y = m x
where "m" is the slope. In this case, the slope represents the number of houses Patty paints per month, that is, m = 3 houses per month.
The final linear equation is:
y = (3 houses/month) x
Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
