Answer:

a. 45

b. -4

Step-by-step explanation:

f(x) = -6(-8) - 3

f(x) = 48 - 3 = 45

21 = -6x - 3

24 = -6x

-4 = x

GIVING AWAY 10 POINTS!!!!!! What is the solution to the system of equations? x = y + 4
slega [8]

Answer:

x= -6, y= 10

Step-by-step explanation:

x= y + 4

2x = 3y - 2

If we replace "x" with "y+4" in the second equation we get:

2(y+4) = 3y - 2

2y + 8 = 3y - 2

2y - 3y = -2-8

-y = -10

y = 10

Now we can go back to the first equation and solve for x:

x = y + 4

x = 10 + 4 = 14

Enter the explicit rule for the sequence
Softa [21]
Let's take a look at the first few numbers in the sequence based on the given rule:

a_{1}=6\\ a_{2}= \frac{1}{4}(6)\\ a_3= \frac{1}{4}\big( \frac{1}{4}\big)6= \big(\frac{1}{4}\big)^2(6)\\ a_{4}= \frac{1}{4} \big(\frac{1}{4}\big)^26= \big(\frac{1}{4}\big)^3(6)

Inspecting this pattern it seems like the power \frac{1}{4} is being raised to is always one less than the number of the sequence, so if we were on the nth number in the sequence, that part of the expression would be \big(\frac{1}{4} \big)^{n-1}. We also know that we'll be multiplying whatever we get from that by 6, so we can write the full explicit rule for our sequence as

a_n=6\big( \frac{1}{4} \big)^{n-1}

Where a_n is the nth number in our sequence.
