Answer:

see explanation

Step-by-step explanation:

A quadratic has a squared variable , this equation does not

The general form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

The equation here

x = 5 - 3x ( add 3x to both sides )

4x = 5 is not in quadratic form and is a linear equation, since the variable is x not x²

Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x  

2

+7x−8=0, b. (x+2)2=49(x+2)  

2

=49, c. 5x2−x−7=05x  

2

−x−7=0, d. x2+4x=−1x  

2

+4x=−1.

Answer:

x = 12

Step-by-step explanation:

Given

4(x - 5) = 8x + 4 - 6x ← distribute left side and simplify right side

4x - 20 = 2x + 4 ( subtract 2x from both sides )

2x - 20 = 4 ( add 20 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

What are the solutions to the expression x^2-8x=24
labwork [276]

Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)

Step-by-step explanation:

x^2-8x=24 <- subtract 24 from both sides

x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a

-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify

(-(-8) +/- 4sqrt(10) )/2 <- sepereate

(-(-8) +/4sqrt(10) )/2 ,  (-(-8) - 4sqrt(10) )/2 <- simplify

2(2+sqrt(10)) , 2(2-sqrt(10) =x

Cellular phone service that charges per-minute will charge $70 for 270 minutes. How much would 1260 minutes cost? Round your ans
gulaghasi [49]
$70 = 270 min
x = 1260 min
Where x is the charge of phone service per 1260 min.

Cross multiply:
1260 * 70 = 270 * x
88200 = 270x
88200/270 = x
x = 326.67

The total charge of cellular phone service for 1260 min is $326.67
