Solve the equation.
-3(3n + 4) = 6
Answer:
n=-2
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(3n+4)=6
Step 1: Simplify both sides of the equation.
−3(3n+4)=6
(−3)(3n)+(−3)(4)=6(Distribute)
−9n+−12=6
−9n−12=6
Step 2: Add 12 to both sides.
−9n−12+12=6+12
−9n=18
Step 3: Divide both sides by -9.
−9n
−9
=
18
−9
n=−2
Answer:
n = -2
Step-by-step explanation:
-3(3n + 4) = 6; multiply -3 to both 3n and 4.
-9n - 12 = 6; add 12 on both sides.
-9n = 18; divide -9 on both sides to isolate the variable n.
n = -2
Which equation represents a line which is parallel to the line
6x + 7y = –49?
Answer: y= 7/6x-5
Step-by-step explanation:
The equations of parallel lines have the same slope or rates.
The equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
The equation is given as:
[tex]\mathbf{6x + 7y = -49}[/tex]
Make 7y the subject
[tex]\mathbf{7y = -6x-49}[/tex]
Make y the subject
[tex]\mathbf{y = -\frac{6}{7}x -7}[/tex]
A linear equation is represented as:
[tex]\mathbf{y =mx + b}[/tex]
Where m represents the slope.
So, we have:
[tex]\mathbf{m = -\frac 67}[/tex]
Parallel lines have the same slope.
So, the slope of the line is [tex]\mathbf{m = -\frac 67}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
Substitute [tex]\mathbf{m = -\frac 67}[/tex]
[tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
Hence, the equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]

which of the following best describes the quadratic function below ?
A. a parent function
B. an inverse function
C. opens right
D. opens down
Option A is correct, a parent function best describes the quadratic function.
The quadratic function with a vertex at the origin and opening upward is best described as a parent function.
A parent function is the most basic form of a particular type of function.
In the case of quadratic functions, the parent function is f(x) = x².
It has a vertex at the origin (0, 0) and opens upward.
Therefore, a parent function best describes the quadratic function.

What is the value of the expression? 1.8 - 0.9
Answer:
0.9
Step-by-step explanation:
The equivalent value of the expression 1.8-0.9 = 0.9
Given data:
The first decimal number is represented as p.
The value of p = 1.8
The second decimal number is represented as q.
The value of q = 0.9
The expression A = p - q
On simplifying the equation:
A = 1.8 - 0.9
On subtracting both the decimals:
A = 0.9
Therefore, the value of A is 0.9
Hence, the expression is A = 0.9
