Solve each quadratic equation by factoring and using the zero product property.
Iteru [2.4K]

Answer:

x=5                            x=6

Step-by-step explanation:

x^2 - 8x + 30 = 3x

Subtract 3x from each side

x^2 - 8x-3x + 30 = 3x-3x

x^2 - 11x + 30 = 0

What 2 numbers multiply to 30 and add to -11

-5*-6 = 30

-5+-6 = -11

(x-5) (x-6) =0

Using the zero product property

x-5 = 0  and x-6 =0

x-5+5 =0+5   and x-6+6 =0+6

x=5                            x=6

a train makes a trip at 65 mi/h. A plane traveling 130 mi/h makes the same trip in 3 fewer hours. Write and solve an equation to
Rudik [331]

The formula used for calculating the time is:

t = d / v

where t is time, d is distance and v is velocity

 

We know that the difference in the two times is 3 hours, therefore:

d / 65 – d / 130 = 3

 

Calculating for d:

d = 30 / (1/65 – 1/130)

<span>d = 3900 miles</span>

A teacher collects data on the number of hours, s, his students spend studying and the number of hours, t, they spend watching T
Sidana [21]
Since there is a negative correlation, evident by the negative slope of the equation of the line given to be -0.5, if we take t as 0, we get an equation of,
                                            s = 3.6
This means that if a student does not watch television, he or she spends a maximum of 3.6 hours studying.
