(6x - 3) - (-3x + 2)
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333

2. $14 flat fee
Step-by-step explanation:
In this case, [tex]f(x)[/tex] where [tex]x[/tex] is time (hour). $14 dollar stays constant when [tex]x = 0[/tex]. This is the flat rate fee.
Let's do a sanity check:
[tex]f(1) = 6(1) + 14 = 20[/tex]
[tex]f(1.5) = 3(1.5) + 14 = 23[/tex]
[tex]f(2) = 6(2) + 14 = 26[/tex]

Simplify each of the following equationS and solve for x
7 - 3x = -x + 1
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
[tex]7 = 2x + 1[/tex]
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
[tex]6 = 2x[/tex]
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
[tex]3 = x[/tex]

Answer:
QS = 38
Step-by-step explanation:
First, we need to find the value of x.
Given that R is the midpoint of Q and S, that means QR = RS.
6x-11 = 2x+9
Solve.
x = 5.
To find QS, we need to solve the following equation:
6x-11 + 2x+9
Substitute 5 for x.
6(5)-11+2(5)+9

my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30

a. r= 3-2 cos theta
b. r= 3- sine
C. r= 3 - cos
d. r = 2 - 2 cos theta
Please select the best answer from the choices provided
Answer:
C. r = 3 - cos theta
Step-by-step explanation:
The other user who answered was correct.
The equation is belongs to the graph of the limacon curve is r = 3 - cos [tex]\theta[/tex]
The correct option is C.
At θ = 180°, the value of r is positive, but just a fraction of the value at
θ = 0°. This eliminates choices 'b' and 'd'.
As, the equation of a horizontal cardiod is r= a ± a cos θ.
Here, from the figure we have horizontal cardiod.
Then, the equation is belongs to limacon curve is r = 3 - cos [tex]\theta[/tex].
