What is the first term in the sequence for which d = -2 and a7 = 3?

AnnZ [28]

Answer:

Final answer is c. 15

Step-by-step explanation:

We need to find about what is the first term in the sequence for which d = -2 and a7 = 3

We will use nth term formula of arithmetic sequence.

$a_n=a+\left(n-1\right)d$

we have been given a7 that means 7th term is 3

so plug n=7, d=-2 and a_n=3 into above formula

$3=a+\left(7-1\right)(-2)$

$3=a+6(-2)$

$3=a-12$

$15=a$

Hence final answer is c. 15

-2x - 6y = -24 X-8y = -10

Debora [2.8K]

Answer:

x = -26 and y = -2

I hope this is the answer you are looking for

Step-by-step explanation:

x-8y = -10 => add 8y to both sides

+8y = +8y

x = -10+8y

-2(-10+8y) -6y = -24 => intersect what you got into the first equation

20-16y-6y = -24 => Distribute the -2

20-22y = -24 => subtract 20 in both sides

-20 = -20

-22y = -44 => divided by -22 in both sides

/-22 = /-22

y = -2

x-8(-2) =-10 => intersect the y into the other equation

x+16 = -10 => multiply -8*-2

-16 = -16

x = -26 => subtract 16 in both sides.

Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

Answer: A. -32.75

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$
