On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.

First, let's find out how much $92 less is:

48 - 92 = -44

We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.

The correct answer is C. The 14th.

Hope this helps!! :)

(9x-9)(9×+9), your finding the difference between two squares. im have some trouble in how to solve it.

sergejj [24]

Answer: Your answer is 0 (F.O.I.L) first. outer. inner. last. Or you could use what my teacher calls the magic box

Step-by-step explanation:

So for the boxes you multiply for example the top left box you multiply the 9 above it and the 9 to the left or like the top right box you multiply the -9 above it and the 9 on the outside of the box to the left

For each sequence, find the first 4 terms and the 10th term. A) n+5 B)2n-1

snow_tiger [21]

Answer:

see explanation

Step-by-step explanation:

(a)

To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.

a₁ = 1 + 5 = 6

a₂ = 2 + 5 = 7

a₃ = 3 + 5 = 8

a₄ = 4 + 5 = 9

For the 10 th term substitute n = 10, that is

a₁₀ = 10 + 5 = 15

The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15

(b)

Substitute n = 1, 2, 3, 4 and 10 into the n th term formula

a₁ = 2(1) - 1 = 2 - 1 = 1

a₂ = 2(2) - 1 = 4 - 1 = 3

a₃ = 2(3) - 1 = 6 - 1 = 5

a₄ = 2(4) - 1 = 8 - 1 = 7

a₁₀ = 2(10) - 1 = 20 - 1 = 19

The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19

a) n² + 6

n=1

1² + 6 = 1 + 6 =7

n=2

2² + 6 = 4 + 6 = 10

n=3

3² + 6 = 9 + 6 =15

n=4

4² + 6 = 16 + 6 =22

7, 10, 15, 22

n=10

10² + 6 = 100 + 6 =106

10 th term-106

b) 3n²

n=10

3 x 10² = 3 x 100= 300

10th term- 300

Hope this helps!
