Answer 1

Answer:

Answer:

OPTION B: y = $(1)/(2)$ x - 2

Step-by-step explanation:

To find the equation of the line substitute the value of x and compare the corresponding value of y.

OPTION A:

y = 2x + 4

Substitute x = 0. We get, 2(0) + 4 = 4

When x = 0, y = -2 $\ne$ 4.

OPTION B:

y = $(1)/(2)$ x - 2

Substitute x = 0, we get $(1)/(2) (0) - 2$

= -2

When x = 2, $(1)/(2)(2) - 2$ = 1 - 2

=-1

Similarly, When x = 4, $(1)/(2)(4) - 2 = 2 - 2$

= 0.

Since, all the values are satisfied, OPTION B is the answer.

Substitute OPTION C and OPTION D. They do not satisfy the values either.

103 + 21 = _ + 103 please help

Answers

This is the commutative property of addition. It basically says, x+y=y+x.
To answer your question, 103+21=21+103

$103 + 21 = Unknown + 103$

$Unknown = 21$

$21+103$

Gary invested $1,000 into an account earning interest at an annual rate of 5% compounded annually. Each year, he deposited an additional $1,000, and made no withdrawals. When he closed the account, he had a balance of $4,525.64. How much interest would Gary earn in that same time if he invests $10,000 and deposits $10,000 into the account each year?

Answers

so first we need to find out how much interest he earned a year so 525.64 divided by 4 which is 131.41 in interest a year so that 5% percent

so 10000 $ for 4 year he would earn 1900.5 so he would have 11,900.5
