Answer:
The system of equations is
and
Fred's age is 36 years old and Nathan's age is 9 years old
Step-by-step explanation:
Let
f -----> Fred's age
n ----> Nathan's age
we know that
-----> equation A
----> equation B
equate the equations and solve for n
Find the value of f
therefore
Fred's age is 36 years old and Nathan's age is 9 years old
Answer:
x= -2/3 and 6
Step-by-step explanation:
3x²-16x-12
3x²-18x+2x-12
(3x²-18x)+(2x-12)
3x(x-6)+2(x-6)
(3x+2)(x-6)
x= -2/3 and 6
Answer:
55
Step-by-step explanation:
bc
The equation of the line is
<u>Step-by-step explanation:</u>
- The line passes through the point (2,-4).
- The line has the slope of 3/5.
To find the equation of the line passing through a point and given its slope, the slope-intercept form is used to find its equation.
<u>The equation of the line when a point and slope is given :</u>
⇒
where,
- m is the slope of the line.
- (x1,y1) is the point (2.-4) in which the line passes through.
Therefore, the equation of the line can be framed by,
⇒
⇒
Take the denominator 5 to the left side of the equation.
⇒
Now, multiply the number outside the bracket to each term inside the bracket.
⇒
⇒
Divide by 5 on both sides of the equation,
⇒
Therefore, the equation of the line is
