Answer:
B. he didn't combine -3 and -9 correctly
The error that Austin made in his work is Austin did not combine -3 and -9 correctly.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that solved the equation -3 + 7x - 9 + 8x = 54 as shown below.
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
We need to check where did Austins has done wrong.
-3 + 7x - 9 + 8x = 54
15x-12=54
For Austin while combining -3 and -9 he got -6 which is wrong.
So Austin did not combine -3 and -9 correctly.
Hence, the error that Austin made in his work is Austin did not combine -3 and -9 correctly.

What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)
Answer: y=4x+6
Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.
Answer:
[tex]y = 4x+6[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
[tex]y = mx+b[/tex]
Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:
[tex]y = 4x+b[/tex]
To find the value of b, we use the point (0,6):
[tex]6=4*0+b[/tex]
Solving:
[tex]b=6[/tex]
Thus, the equation in slope-intercept form of the required line is
[tex]\boxed{y = 4x+6}[/tex]
which is the first step in simplifying the expresion 2(x+3)+5?
Answer:
[tex]2x + 11[/tex]
Step-by-step explanation:
1) Expand by distributing terms.
[tex]2x + 6 + 5[/tex]
2) Collect like terms.
[tex]2x + (6 + 5)[/tex]
3) Simplify.
[tex]2x + 11[/tex]
The first step to do this equation is to expand.which means to solve whats inside the parentheses first. If you expand you'll get a answer of 2x + 11.
How do you do this question?
For A to B, or segment AB, we have the points (1,1) and (4,3). (x1, y1) = (1,1) and (x2, y2) = (4,3);
x = 1 + t(4 - 1)
y = 1 + t(3 - 1)
A to B => (x = 1 + 3t, y = 1 + 2t)
We can apply a similar process for BC and AC. For BC we have (x1, y1) = (4,3) and (x2,y2) = (1,7);
x = 4 + t(1 - 4)
y = 3 + t(7 - 3)
B to C => (x = 4 - 3t, y = 3 + 4t)
(x1, y1) = (1, 1) and (x2, y2) = (1, 7);
x = 1 + t(1 - 1)
y = 1 + t(7 - 1)
A to C => (x = 1, y = 1 + 6t)

Jade and Jackson are considering a $210,000 mortgage for 30 years at 5.7%. With this information, their monthly payment would be $1218.84.
If they make only the minimum payment each month, what is the total payback of this loan?
How much of this total payback is interest?
Answer:
Jade and Jackson
The total payback of this loan = $438,782.72
The interest of this total payback is $228,782.72
Step-by-step explanation:
a) Data and Calculations:
Mortgage = $210,000
Interest rate of mortgage = 5.7%
Monthly payment = $1,218.84
Using an online calculator for Mortgage Payoff, the Original Payoff Schedule is:
Monthly Pay = $1,218.84
Total Payments = $438,782.72
Total Interest = $228,782.72
Answer:
Step-by-step explanation:
1218.84⋅12⋅30=$438,782.40
The total interest paid is the total payback less the amount borrowed.
$438,782.40−$210,000=$228,782.40

Answer:
1/5
Step-by-step explanation:
Judge the following reasoning as true or false.
You are working for a tech company. You came up with an algorithm that performs a needed operation on n inputs in order of n operations. Someone else in the company simultaneously came up with an algorithm that performs the same task in order of log(n) operations. Then it follows necessarily that your algorithm will require more operations to perform this task and is therefore inferior and should not be used.
a) true
b) false
