This exercise is asking you to find the value of x or solve for x, to do so you have to isolate or leave x alone by doing different mathematical operations according to the given equation.
The given equation is -x=3-4x+15, which is a three step equation meaning that in order to solve for x you have to perform three different mathematical operations, in this case combining of like terms, addition, and division.
-x=3-4x+15 Combine like terms
-x=-4x+18 Add 4x in both sides
3x=18 Divide by 3 in both sides to isolate x
x=6
The value of x in the equation is 6 or letter C from the given choices.
The factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)
<h3>Factoring quadratic expressions</h3>
From the question we are to factor the given quadratic expressions
y = x² +7x -2x - 14
y = x(x +7) -2(x +7)
y = (x -2)(x +7)
y = x² -9x +6x - 54
y = x(x -9) +6(x -9)
y = (x +6)(x -9)
y = x² +6x +2x +12
y = x(x +6) +2(x +6)
y = (x +2)(x +6)
y = x² -6x -5x +30
y = x(x -6) -5(x -6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = x² +9x -x -9
y = x(x +9) -1(x +9)
y = (x -1)(x +9)
y = (x +4)(x -4)
Hence, the factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)

Answer:
The percentage of discounted tickets with respect to total tickets is 75 %
Step-by-step explanation:
Given as :
The total tickets of amusement park = 5,000
The total discounted tickets of amusement park = 3,750
Let The percentage of discounted tickets with respect to total tickets = D %
Now, According to question
The discounted percentage = × 100
or, D = × 100
or, D = 0.75 × 100
or D = × 100
∴ D = 75 %
So, percentage discounted tickets = D = 75 %
Hence The percentage of discounted tickets with respect to total tickets is 75 % . Answer
The answer that i got is a
