Answer:
<u>Richard’s account balance at the end of the week = US$ 132.45</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Richard’s checking account balance at the beginning of the week = $57.34
2. What was Richard’s account balance at the end of the week?
Deposits of the week = US$ 163.75
Expenses of the week = Groceries + Credit card bill + Gas
Expenses of the week = 25.37 + 50 + 13.27
Expenses of the week = US$ 88.64
Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week
Replacing with the real values:
Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64
<u>Richard’s account balance at the end of the week = US$ 132.45</u>
slope = 2 and y-intercept = 0
the equation of a line in ' slope- intercept form ' is
y = mx + c ( mis the slope and c the y-intercept )
given 2x - y = 0 ( add y to both sides )
2x = y or y = 2x + 0 ← in slope-intercept form
with slope m = 2 and y-intercept c = 0
Answer:
y = 3x + 5
Step-by-step explanation:
slope:
11 - (-1) / 2 - (-2) = 12/4 = 3
slope intercept form is y = mx + b, so right now you have m = 3:
y = 3x + b
now, since you know x = -2 and y =-1 is a solution, you can plug those values in:
-1 = 3 * -2 + b
-1 = -6 + b
5 = b
This means the equation is y = 3x + 5
You ca go to tiger math and put in any equation and it will give you the answer to any of them.
