Starting balance: $275.35
Deposits: $987.25 + $100 = $1087.25
Withdrawals: $15.00 + $43.22 + $57.26 = $115.48

Current balance = $275.35 + $1087.25 - $115.48

Current balance = $1247.12

The expression log 3 (x-4) is undefined for all values such that
suter [353]
Translate it

remember that log_a(b)=c translates to a^c=b
so we can say it equals y
so
log_3(x-4)=y translates to 3^y=x-4

we want to find the values of x that make it undefined
well, we know that 3^y must be greater than 0
so we do
it is defined for
x-4>0
add 4
x>4

it is defined for all values such that x>4

Write an equation in slope-intercept form that goes through (12, 4) and (20,8).
spayn [35]

Answer:

Equation in slope-intercept form that goes through (12, 4) and (20,8) is: y = \frac{1}{2}x-2

Step-by-step explanation:

Given two points are:

(x_1,y_1) = (12,4)\\(x_2,y_2) = (20,8)

Slope intercept form of line is given as:

y = mx+b

Here m is the slope of the line and b is the y-intercept.

Slope of a line is calculated by the formula:

m = \frac{y_2-y_1}{x_2-x_1}

Putting the values

m = \frac{8-4}{20-12}\\m = \frac{4}{8}\\m=\frac{1}{2}

Putting the value of slope in slope-intercept form we get

y = \frac{1}{2}x+b

To find the value of b, any one point will be put in the equation

Putting the first point (12,4) in the equation

4 = \frac{1}{2}(12) + b\\4 = 6+b\\b = 4-6\\b = -2

Putting the value of b

y = \frac{1}{2}x-2

Hence,

Equation in slope-intercept form that goes through (12, 4) and (20,8) is: y = \frac{1}{2}x-2

Use the substitution method to solve each system of equations. Write the answer in ordered pairs.
tatyana61 [14]

x -y = 1

5x + 3y = 45

Solve the first equation for x: x = y + 1

Substitute x in the second with y + 1

5x + 3y = 45

5(y + 1) + 3y = 45

5y + 5 + 3y = 45

8y + 5 = 45

8y = 40

y = 5

Substitute 5 for y in x = y + 1

x = y + 1

x = 5 + 1

x = 6

Answer: (6, 5)
