Answer:
20 years old
Step-by-step explanation:
Let us assume that the son's age is x.
Therefore,
2.5x = 55 - 5
2.5x = 50
x = 20 years old

Write the equation of the line that passes through the points (-6, -9) and (7, 7).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
[tex]\displaystyle y + 9 = \frac{16}{13} ( x + 6 )[/tex]
Step-by-step explanation:
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Given a line passes through points A(x1,y1) and B(x2,y2), the slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (-6,-9) and (7,7), thus the slope is:
[tex]\displaystyle m=\frac{7+9}{7+6}=\frac{16}{13}[/tex]
Now we apply the point-slope formula using the point (-6,-9):
[tex]\mathbf{\displaystyle y + 9 = \frac{16}{13} ( x + 6 )}[/tex]
This equation is expressed in the required format
The equation of the line passing through the given points is required.
The equation of the line is [tex]y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]
The points are [tex](-6,-9)[/tex] and [tex](7,7)[/tex]
The equation is
[tex]y-y_1=\dfrac{\Delta y}{\Delta x}(x-x_1)\\\Rightarrow y+9=\dfrac{7+9}{7+6}(x+6)\\\Rightarrow y+9=\dfrac{16}{13}x+\dfrac{96}{13}\\\Rightarrow y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]
The equation of the line is [tex]y=\dfrac{16}{13}x-\dfrac{21}{13}[/tex]

Analyzing an Error
A student simplifies (6b + 4r) – (2b + r) and says that the result is 4b + 5r. Explain the error and describe the correct steps to simplify the expression.
Answer:
4b +3r
The student did not subtract both terms in the second parentheses
Step-by-step explanation:
(6b + 4r) – (2b + r)
Distribute the minus sign to all terms in the second parentheses
6b + 4r – 2b - r
Combine like terms
6b -2b +4r -r
4b +3r
The student did not subtract both terms in the second parentheses
Answer:
4b+3r
Step-by-step explanation:
(6b+4r)-(2b+r)
Distribute the negative symbol across the second set of parenthesis.
6b+4r-2b-r
Add like terms
4b+3r
Error: the student added r instead of subtracting it. They most likely only distributed the negative to the 2b.

Step-by-step explanation:
I’m assuming your saying: 6^2 · 6^4, which is equivalent to 6^6 because if two numbers have the same base (in this case it’s 6), then you just add the exponents: add the exponents 2 + 4 = 6 ⇒ 6^6
6^6 = 46656

Step-by-step explanation:
3 is the greatest common factor between 21 and 9
put 3 outside the parenthesis and divide both numbers by 3
3(7a + 3)
Answer:
3(7a+3)
Step-by-step explanation:
Find the common factor
3 multiplied by 7 equals 21, and 3 times 3 equals 9
Take the common factor out of the parenthesis
3( _a+_)
and put in 7 and 3 in the appropriate spots
3(7a+3)
double check
3 times 7 is 21, 3 times 3 is 9
3(7a+3)= 21a+9

Graph x+3y=-6 using the x and y-intercepts.
Answer:
use points (0, -2) and (-6, 0)
Step-by-step explanation:
set up the equation in y-intercept form
x + 3y = -6
3y = -x - 6; divide by 3
y = [tex]\frac{-1}{3}[/tex] x - 2; you can the y-intercept is -2 or (0, -2)
Now to find where the graph cross the x-axis at y=0
0 = [tex]\frac{-1}{3}[/tex] x - 2; move the 2 to the other side
2 =[tex]\frac{-1}{3}[/tex] x ; multiply by -3
-6 = x; which is point (-6,0)
