A box of fruit has three times as many nectarines as grapefruit. Together there are 64 pieces of fruit. Write the equation that
Basile [38]

Answer:

4g = 64

Step-by-step explanation:

Let n = the number of nectarines

and g = the number of grapefruit

We have two conditions that must be satisfied to represent the situation:

(1)         n = 3g

(2) n + g = 64

If you need one equation, we can substitute (1) into (2) and get

4g = 64

Explain why x^2 = -81 does not have a solution.
Evgesh-ka [11]

Remember, the graph of a line represents every point that is a possible solution for the equation of that line. So when the graphs of two equations cross, the point of intersection lies on both lines, meaning that it is a possible solution for both equations. When the graphs of two equations never touch, there are no shared points and there are no possible solutions for the system. When the graphs of two equations lie on top of one another, they share all their points and every one is a possible solution.

If f(x)=x^4+3x^3-x^2+6, find f(-3).
docker41 [41]

Answer:

f(-3) = -3

Step-by-step explanation:

Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.

f(x)=x^4+3x^3-x^2+6\\f(-3)=(-3)^4+3(-3)^3-(-3)^2+6

Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>

f(-3)=81+3(-27)-9+6

Step 3: Use BEDMAS rules to complete the calculation.

f(-3)=81-81-9+6

f(-3)=-3

Therefore the answer is f(-3) = -3.

GHF is congruent to KHJ, what can you conclude?
Hitman42 [59]
The answer is a. Because because congruent angles are equal. if they are equal and start at the center of a circle this means that they can only travel the same distance before hitting border of circle. this would make their arcs the same
