Well, you know in math, if you say "what is this number of this number?" It always means you multiply those two numbers. So 2/3 of 2 cups would be saying the same if I said 2/3 cups times 2 cups. Anyways, the answer would be 1.3 with a bar notation over the 3.
F1P - F2P = k ;
F1P =
F2P =
31.04 - 31 = 0.04 => k = 0.04 ;
Answer:
7
Step-by-step explanation:
Explanation of
f(x) = 2x + 1 for x ≥ 3
f(x) = 3x - 3 for x < 3
when the x in f (x) is greater than or equal to 3 we use the equation 2x + 1
When the x in f (x) is less than 3 we use the equation 3x - 3
we want to find f ( 3 )
because x is greater equal to 3 we use the equation 2x + 1
so to find f ( 3 ) we simply plug in the value of x into the equation
f ( 3 ) = 2(3) + 1
multiply
f ( 3 ) = 6 + 1
add
f ( 3 ) = 7
3. Translation that is 6 units to the left and 5 units up translate the point (x,y) into the point (x-6,y+5).
<u>Example:</u> if you translate the origin (0,0) 6 units to the left and 5 units up, then you obtain point (-6,5).
Answer 3: correct choice is D.
4. A reflection across the y-axis changes the x-values into opposite and y-values remain the same. Then the rule is (x,y)→(-x,y).
<u>Example:</u> if you reflect the point (2,3) across the y-axis, then you get the point (-2,3).
Answer 4: correct choice is B.
