Step-by-step explanation:
we see f(x), which is |x|.
and we see g(x), which is clearly the same basic graph, it is just shifted 3 units down in y direction.
shifts are simply done by keeping the original function definition and then add it subtract a certain constant that then adapts every original functional value.
so, a shift down by 3 units is done by adding -3.
therefore, C is the correct answer (the original f(x) - 3).
Answer:
4
Step-by-step explanation:
Its four because:
4 x 3 = 12
12 + 4 = 16
4 x 4 = 16
Four times times three plus four is like saying four times four.
Answer: last option.
Step-by-step explanation:
- Subtract the fractions that are in the numerator.
- Add the fractions that are in the denominator.
Then:
- Multiply the numerator of the fraction on the top by the denomianator of the fraction on the bottom.
- Simplify.
Then:
Answer: B, makes the most sence
Step-by-step explanation:
The ratio of 50% content to 25% content is
.. (40-25) : (50-40) = 15:10 = 3:2
There is a total of 5 "ratio units" in this ratio, so each is representing 35 kg/5 = 7 kg of alloy.
21 kg of 50% alloy and 14 kg of 25% alloy should be used.
