The beginning balance on the monthly bank statement for Sierra's checking

irga5000 [103]

Answer:

A. She had $170.47 more in debits than in credits.

Step-by-step explanation:

In a bank account, when money is deposited, the bank credits the bank accounts while a withdrawal is debited to the account hence, if the monthly bank statement for Sierra's checking account was $402.22, and the ending balance was $231.75, the change in the account is

= $402.22 - $231.75

= $170.47

Since there was a drop in the balance comparing the beginning and ending balances, it means there were more withdrawals than deposits (in amount).

PLEASE HELP ASAP!!! I AM REALLY STUCK AND WILL AWARD BRAINLIEST!!!

Setler [38]

Answer:

Does not go

Step-by-step explanation:

$x = \frac{10}{3} \\ y = - 2$

$y = kx \\ - 2 = k( \frac{10}{3} ) \\ \\ k = \frac{ - 2 \times 3}{10} \\ \\ k = \frac{ - 1 \times 3}{5} \\ \\ k = - \frac{3}{5}$

So the equation is

$y = - \frac{ 3}{5} x$

M(-10, 15)

$x = - 10 \\ \\ y = - \frac{3}{5} x \\ \\ y = - \frac{3}{5} ( - 10) \\ \\ y = \frac{3}{5} (10) \\ \\ y = 3 (2) \\ \\ y = 6$

The graph Does not go through point M bcz when the value of x = - 10 then the value of y is 6, not 15

Answer:

Step-by-step explanation:

It is a right triangle as it has a right angle (you can draw a little square to show that).

It's side are already recorded, so I tried my best, though I'm not sure it's correct.

Hope that helps!

Use the graph to evaluate the function for the given input value.

Angelina_Jolie [31]

The evaluation of the function for the given f(-1), f(1) input value is mathematically given as

f(-1) = -8
f(1) = -12

<h3>What is the evaluation of the function for the given f(-1), f(1) input value?</h3>

In the field of mathematics, an assignment of one element from set Y to each and every element in set X is the definition of a function. This particular set, X, is referred to as the function's domain, and this particular set, Y, is referred to as the function's codomain. Historically, functions have been seen as an idealization of the way in which one variable relies on another variable.

-1 and 1 are both considered to be input when evaluating the function f, which is represented by the graph.

Since the inputs are on the x-axis, the graph demonstrates that the value of the function f at -1 is about -8 when x equals -1.

When x equals 1, the value of the function f is close to -12.
