Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.
Answer:
Step-by-step explanation:
We know that the transformations of a cosine equation can be shown as:
y=±a(b(x-h))+k
Where 'a' is the amplitude
'b' is the horizontal change (Do 2π/b to find the period)
'h' is the horizontal shift
and 'k' is the vertical shift or midline.
------------------------------------------------------
If the amplitude is 4, we can assume a=4.
Since the period is 4/7, we can solve for the 'b' value by:
Next, since the midline is 2, we know that a vertical shift of 2 occurred. Thus, the 'k' value is 2.
Writing this equation gives us:
13.5·18=243

Answer:
20 inches per minute
Step-by-step explanation: You can find the answer by dividing the inches (120) by the minutes (6), 120/6 = 20
24 hours
Step-by-step explanation:
If 6 motorcycles are made in 9 hours we indicate the ration as;
6 motorcycles = 9 hours
How many will 16 motorcycles take;
16 motorcycles = ? hours (which we shall assign as x hours)
We shall cross multiply the two rations;
6x = 16 * 9
X = 144/6
X = 24
= 24 hours
