Keira is reviewing her checking account statement from the bank. Her starting balance and transactions are listed.
-Starting balance of $49.15.
-Spent $16.23 at Wal Mart.
-Deposit from birthday check of $35.00. -Dinner at Chick-fil-A for $8.34.
-Withdrawal cash at the ATM of $20.
If reconciled, her bank statement should have a balance of
$9.58
$39.58
$79.58
$72.04
Answer:
39.58
Step-by-step explanation:
49.15-16.23=32.92
32.92+35=67.92
67.92-8.34=59.58
59.58-20=39.58
Her balance is $39.58
Hope this helps
Answer:
49.15 - 16.23 + 35.00 - 8.34 - 20 = 39.58
What is the value of y in (1/2)x + 3 = (1/3)y - 2 if x = 28/3?
Answer:
y = 29
Step-by-step explanation:
x/2 + 3 = y/3 - 2
28/3 ÷ 2 = 14/3
14/3 + 9/3 = y/3 - 6/3
23/3 + 6/3 = y/3
29/3 = y/3 ∴ y = 29

Find 2a-3b as a column vector
Answer:
(-9, 14)
Step-by-step explanation:
Let the column vector be represented as a = (3, 4) and b = (5, -2)
2a = 2(3,4)
2a = (6,8)
3b = 3(5, -2)
3b = (15, -6)
Take the difference 2a - 3b
2a - 3b = (6,8) - (15, -6)
2a - 3b = (6-15, 8 -(-6))
2a - 3b = (-9, 14)
Hence the column vector is (-9, 14)
We want to find 2a - 3b as a column vector, we will get:
[tex]2a - 3b = \left[\begin{array}{ccc}-9\\14\end{array}\right][/tex]
So we want to perform a sum (difference actually) of vectors, we have that:
[tex]a = \left[\begin{array}{ccc}3\\4\end{array}\right] \\\\\\b= \left[\begin{array}{ccc}5\\-2\end{array}\right][/tex]
Remember that when we multiply a vector by a scalar, each component gets multiplied by that scalar, so we have:
[tex]2a = \left[\begin{array}{ccc}2*3\\2*4\end{array}\right] = \left[\begin{array}{ccc}6\\8\end{array}\right] \\\\\\3b= \left[\begin{array}{ccc}3*5\\3*-2\end{array}\right] = \left[\begin{array}{ccc}15\\-6\end{array}\right][/tex]
Now we just perform the direct difference:
[tex]2a - 3b = \left[\begin{array}{ccc}6\\8\end{array}\right] - \left[\begin{array}{ccc}15\\-6\end{array}\right] = \left[\begin{array}{ccc}6 - 15\\8 + 6\end{array}\right] = \left[\begin{array}{ccc}-9\\14\end{array}\right][/tex]

-9,7 with a rotation of 180°
Answer:
(9,-7)
Step-by-step explanation:
Anytime you rotate a coordinate point around the coordinate plane at 180°, each coordinate changes from (x,y) to '(-x, -y). This means they will become the opposite of their original number.
Determine whether the vertex of the function is a maximum or minimum, and find its coordinates.

What is the result of subtracting the second equation from the first?
-4x-2y=-2
x-2y=9
Answer:
Given:
-4x - 2y = -2 x - 2y = 9Subtracting:
-4x - 2y - (x - 2y) = -2 - 9-4x - 2y - x + 2y = - 11-5x = -115x = 11x = 11/5x = 2.2You can now find y:
2.2 - 2y = 92y = 2.2 - 92y = - 6.8y = -6.8/2y = -3.4Solution (2.2, -3.4)

Find the value of x. i’m so lost. it’s geometry!
Answer:
150°
Step-by-step explanation:
Consider OACB,
Here <CAO =<CBO= 90° ( As they are tangents)
<ACB= 30°
Now, <CAO +<CBO+<ACB+x= 360°
90°+90°+30°+x= 360°
x= 150°
Hope it helps
Answer:
150°
Step-by-step explanation:
Construct a line OC, and consider the resulting triangles ΔOAC.
<AOB=(1/2)x
<CAO=90
<ACO=30/2=15
Angles in a triangle add to 180, so
90+15+(x/2)=180
x/2=75
x=150°

Answer:
Step-by-step explanation:
Given
x^2 + y^2 - 16y - 36 = 0
x^2 + y^2 - 16y = 36
x^2 + y^2 - 16y + (16/2)^2 = 36 + 8^2
x^2 + (y - 8)^2 = 64 + 36
x^2 + (y - 8)^2 = 100
The center is at (0,8) and the radius is 10
