Answer:

2a^4c-2ac^2-15

Step-by-step explanation:

6a^4c+8ac^2-4a^4c-15-10ac^2

We need to organize this expression into groups of like terms, so we can combine them easier. There are 2 groups of like terms,

6a^4c-4a^4c and 8ac^2-10ac^2

6a^4c-4a^4c+8ac^2-10ac^2-15

Add similar elements:

2a^4c+8ac^2-10ac^2-15

Add, 8ac^2-10ac^2=-2ac^2

=2a^4c-2ac^2-15

Answer:

2a^4c-2ac^2-15

Step-by-step explanation:

Sorry, I not sure if this is right or not cause I don't know if the exponent for -4a^4c is that or -4a^4c-15, but I'm just going to go with -4a^4c. However aside from that you just combine like terms.

Alex73 [517]

Answer:

286 students attended

148 non students attended

Step-by-step explanation:

Given

Tickets = 434

Students = \$4.00

Non-Students = \$6.00

Total = \$2032.00

Solving (a): Number of students

Represent students with S and non students with N

So:

S + N = 434 --- (1)

4S + 6N = 2032 --- (2)

Make N the subject of formula in (1)

N = 434 - S

Substitute 434 - S for N in (2)

4S +6(434 - S) = 2032

Open Bracket

4S + 2604 - 6S = 2032

Collect Like Terms

4S - 6S = 2032 - 2604

-2S = -572

Divide through by -2

S = 286

<em>Hence; 286 students attended</em>

Solving (b):

Recall that

N = 434 - S

N = 434 - 286

N = 148

<em>148 non students attended</em>

Given the function f(x) = 2x + 61 - 4, for what values of x is f(x) = 6?
andrezito [222]

Answer: You must have wrote the equation incorrectly

Step-by-step explanation:

You wanna make f(x) equal to 6

So its 6 = 2x + 57

Subtract 57 from both sides to get -51 = 2x

Divide both sides by 2 to get -25.5
