Heidi solved the equation
3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below:
3x + 12 + 2 = 2 + 5x – 20
3x + 14 = 5x – 18
14 = 2x – 18
32 = 2x
16 = x
Use the drops-downs to justify how Heidi arrived at each step.
Answer:
her first step was) Combining like terms= 12+2
her second step was) Combining like terms/ subtracting 5x from 3x= 5x-3x
her third step was) Adding to both sides 18= 14+18
her last step was) isolating the variable/ dividing 2 from both sides= 32/x.
Hope You Got It!

The slope between the points (4,2) and (1. p) is 4. Find p and write the
equation of the line that has these points in point slope form.
Hint

equation of the line: \y - y1) = m(- X1)
Y1

X1
Answer:
[tex]slope = \frac{y_2 - y_1}{x_2-x_1}\\\\4 = \frac{p-2}{1-4} \\\\4 \times -3 = p -2\\\\-12 + 2 = p \\\\p = -10 \\\\Equation \ of \ line : \\\\(y -y_1) = m(x - x_1)\\\\y - 2= 4(x-4)\\\\y - 2 = 4x -16\\\\y = 4x -14[/tex]
Hi there! The slope formula is:
[tex] \large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]
We know that the slope is 4 but we are missing the value of p. (Define m = slope)
What we have now are:
two ordered pairs (4,2) and (1,p)value of slope = 4We are going to substitute these values and solve the equation for p-term.
[tex] \large{4 = \frac{2 - p}{4 - 1} } \\ \large{4 = \frac{2 - p}{3} } \\ \large{4(3) = \frac{2 - p}{3} (3)} \\ \large{12 = 2 - p} \\ \large{p = 2 - 12 \longrightarrow \boxed{p = - 10}}[/tex]
Hence, the value of p is -10.
Next, we have to write the equation of a line in point-slope form. The point-slope form is:
[tex] \large \boxed{y - y_1 = m(x - x_1)}[/tex]
Define that (x1, y1) = ordered pairs
Since we have two given points, we can either use the first point or second point. Both work.
First Point
For our first ordered pairs (4,2), substitute x1 = 4 and y1 = 2 in the equation.
[tex] \large{y - 2 = 4(x - 4)}[/tex]
Hence, the equation of a line in point-slope form as in (4,2) is y-2=4(x-4)
Second Point
For our second ordered pairs (1,p), we know that p = -10 from the equation that we solved. Therefore (1,p) = (1,-10). Substitute x1 = 1 and y1 = -10 in the equation.
[tex] \large{y - ( - 10) = 4(x - 1)} \\ \large{y + 10 = 4(x - 1)}[/tex]
Hence, the equation of a line in point-slope form as in (1,-10) is y+10 = 4(x-1)
Answer
The value of p is -10 (p = -10)y - 2 = 4(x-4) —> use (4,2) to form an equation. y + 10 = 4(x-1) —> use (1,-10) to form an an equation.Both equations work for point-slope form.

In a scale drawing of a house, 1/2 inch = 1 1/2 feet. If the length of a kitchen is 5 1/2 inches on a scale drawing, what is the actual length of the kitchen?
Answer:
16 1/2 feet
Step-by-step explanation:
The above question is calculated as:
1/2 inch = 1 1/2 feet.
5 1/2 inches = x
Cross Multiply
1/2 inch × x = 5 1/2 inch × 1 1/2 feet
x = 5 1/2 inch × 1 1/2 feet/ 1/2 inch
x = 11/2 × 3/2 ÷ 1/2
x = 11/2 × 3/2 × 2/1
x = 33/2 feet
x = 16 1/2 feet
Therefore, the actual length of the kitchen is 16 1/2 feet

A hiker leaves her camp in the morning. She walks 9 miles west then 10 miles north. Explain how you would find how far she has traveled from her camp.
Answer:
About 13.45 miles ( rounded )
Step-by-step explanation:
You would use the pythagorean theorem to solve this. ([tex]a^{2}[/tex]+ [tex]b^{2}[/tex] = [tex]c^{2}[/tex])
[tex]a^{2}[/tex] would be one length of that triangle, we'll use 9.
[tex]b^{2}[/tex] would be the other length of that triangle, we'll use 10.
So, now you have to square both of them.
[tex]9^{2}[/tex] = 81 ( 9 x 9 ) [tex]10^{2}[/tex] = 100 ( 10 x 10 )
Which you will get 81 and 100. Then you add those two numbers together.
100 + 81 = 181
Now that you have 181, you have to square root 181.
[tex]\sqrt{181}[/tex]
With that you should get 13.45 miles. (rounded)
What are the closing costs for a recent home purchase that includes a mortgage of $80,528 at 1.5 points and attorney's fees of $375 and title fees of $215?
Answer:
1797.92
Step-by-step explanation:
The closing cost for the home percent mortgage can be calculated as follows
= 0.01×1.5×80,528
= 1207.92
1207.92+375+215
= 1797.92
Hence the closing cost for the home purchase is 1797.92
Answer:
$1,797.92

Look at the sequence of numbers.
6 12 18 24
a Write down the next number in the sequence.
b Write down the term-to-term rule.
C Write down the position-to-term rule.
Answer:
Here we have the sequence:
6, 12, 18, 24
We can assume that this is an arithmetic sequence, this is, the difference between any two consecutive terms is always the same, D.
To check this, let's find the difference between the consecutive terms:
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
So we can conclude that this is an arithmetic sequence, and the difference between any two consecutive terms is always 6.
a) Then the next number in the sequence will be equal to the previous number plus 6, this is:
24 + 6 = 30
The next number in the sequence is 30
b) The term-to-term rule is the rule that defines the n-th term based on the previous terms.
Here we already know that each term in this sequence is the previous one plus six, so we can write this as:
Aₙ = Aₙ₋₁ + 6
c) The position-to-term rule is the general one.
Here we need to know that, the first term, A₁ = 6
Then, the n-th term will be A₁ plus (n - 1) times 6.
Then the rule is:
Aₙ = A₁ + (n - 1)*6
Replacing A₁ by its value, the rule becomes:
Aₙ = 6 + (n - 1)*6
