Answer:
C.250
Step-by-step explanation:
If f(x) varies directly with x^2
f(x) = k * x^2
f(x) = 40 when x=2. Substitute these values in
40 = k(2)^2
40 = k*4
Divide by 4
40/4 = 4k/4
10 =k
f(x) = 10x^2
Now we want to find f(x) when x=5. Substituting
f(5) = 10 *5^2
f(5) = 10 *25
f(5) = 250
Answer:
3n - 4
Step-by-step explanation:
for "four less than three times a number" meaning you subtract 4 from the product of 3 and the unknown number.
Answer:
The final simplified form would be 6p^2 + 7m
Step-by-step explanation:
In order to find this, we need to start by putting all the like terms together. First, put all the p^2 terms together.
4p^2 + 2p^2 = 6p^2
Then we do the same thing with the m terms.
5m - m + 3m = 7m
Then for the end result, we just put the two terms together.
6p^2 + 7m
You would move to the left. That is asking -4 + ?. The ? is the same as -5, as -4-5=-4+-5. This would make an answer of negative 9.
7/8 * 7 = 49/8 teaspoons which is 6.125 teaspoons
