Answer:
1.) 12 hours 2.) She made a multiplying error in the table.
Step-by-step explanation:
1.)
First, let's find the slope of this equation:
m = 135 - 81 / 5 - 3
m = 54/2
m = 27
Therefore, the equation should be y = 27x.
Now we substitute 324 for y and solve for x:
324 = 27x
12 = x (Divided 27 on both sides.)
Therefore, someone would have to work 12 hours in order to earn $324.
2.)
For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

What property justifies step 4?
a. Commutative Property of Addition
c. Multiplication Property of Equality
b. Addition Property of Equality
d. Substitution
Answers
Answer:
Step-by-step explanation:
A.
Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.
Equations are expressions separated by an equal sign.
Given the equation:
2(x-3) + 3x = 19
Expand the parenthesis using the distributive law
2x - 2(3) + 3x = 19
2x - 6 + 3x = 19
Collect the like terms
2x + 3x -6 = 19
Step 4
Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:
5x-6 = 19
Step 5
Add 6 to both sides
5x-6+6 = 19+6
5x = 25
x = 25/5
x = 5
Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

Find the midpoint of AB if A(-3. 8) and B(-7. -6)
Answers
The midpoint of AB is (-5, 1).
To find the midpoint of a line segment AB, we average the x-coordinates of the two endpoints and the y-coordinates of the two endpoints.
Given that A has coordinates (-3, 8) and B has coordinates (-7, -6), we calculate the midpoint as follows:
x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2
= (-3 + -7) / 2
= -10 / 2
= -5
y-coordinate of midpoint = (y-coordinate of A + y-coordinate of B) / 2
= (8 + -6) / 2
= 2 / 2
= 1
Therefore, the midpoint of AB is (-5, 1), where -5 is the x-coordinate and 1 is the y-coordinate. This means that the midpoint is equidistant from points A and B, dividing the line segment AB into two equal parts.

(3.9 x 10^-3) + .0026 in scientific notation
Answers
The value of (3.9 × 10⁻³) + 0.0026 in scientific notation is 6.5 × 10⁻³.
What is Decimals numbers?Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.
Decimal number system describes the base 10 number system.
Given are numbers 3.9 × 10⁻³ and 0.0026 added together.
We have to do it in scientific notation.
0.0026 can be written as 2.6 × 10⁻³.
Adding these two numbers together, and taking the common term,
(3.9 × 10⁻³) + (2.6 × 10⁻³) = (10⁻³) (3.9 + 2.6)
= (10⁻³) (6.5)
= 6.5 × 10⁻³
Hence the answer of the sum of (3.9 × 10⁻³) + 0.0026 is 6.5 × 10⁻³ in scientific notation.
