Answer:
I think it is 40.5
Step-by-step explanation:
If each 1cm cube is 12 grams, I figure the other cubes would be proportional and a 1.5cm cube comes up to be 3.375cm^3, not 1 cm^3, thus we multiply the rate to 3.375 to get 40.5 as the mass of the 1.5 cm cube
The value of h(3) is 120 ⇒ B
Step-by-step explanation:
To find the value of f(x) at x = a, do that
- Substitute x by a
- Find the value of f(a)
∵
- To find h(3) substitute x by 3
∴
∵
= 81
∵ (3)² = 9
- Substitute them in the function above
∴ h(3) = 2(81) - 4(9) - 2(3)
∴ h(3) = 162 - 36 - 6
∴ h(3) = 120
The value of h(3) is 120

Answer:
C
Step-by-step explanation:
To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).

Convert to standard form by applying the distributive property and rearranging the terms.

The equation x +2y = -8 is the same equation as 4y + 2x = -16 just doubled----> 2x + 4y = -16
-6q^2 + 4q^2 + 8q - 9a^2
Combine like terms:
-2q^2 + 8q - 9a^2
You cannot combine q^2 to q because they do not have the same number of exponents!
