Answer:
(cx)2-(dy) 2
Step-by-step explanation:
Formula a2-b2= (a+b) (a-b)
By given formula
(cx)2 - (dy) 2 = (cx+dy) (cx-dy)
Answer:
18 square units because units is not described
Step-by-step explanation:
trigonometric fit:
when one side of a triangle is 3 and the other side of the triangle is 4, the big side is 5. so in this case, the dashed line means 3.
3 times 4 equals area of rectangle which is 12
3 times 4 divided by a 2 which is 6 is the half rectangle
Answer:
the function is always increasing
Step-by-step explanation:
if you look at the graph, as x increases, y increases, no matter how small the increase
Answer: 0.3821
Step-by-step explanation:
Let x be the random variable that represents the wages.
Given: Workers have an average wage of $9.00 per hour with a standard deviation of $0.50.
The probability of obtaining a sample mean less than or equal to $8.85 per hour:
The required probability = 0.3821
Answer:
4) add the equations to eliminate x
Step-by-step explanation:
After adding the equations then you can use the value you found for y to substitute back into one of the equations in order to find x
