What is the solution set of the quadratic equation - 2(2x-7)^2 = - 8​​

Mathematics
1 answer:
barxatty [35]3 years ago
8 0

Answer:

see explanation

Step-by-step explanation:

Given

- 2(2x - 7)² = - 8 ( divide both sides by - 2 )

(2x - 7)² = 4 ( take the square root of both sides )

2x - 7 = ± \sqrt{4} = ± 2 ( add 7 to both sides )

2x = 7 ± 2

2x = 7 - 2 = 5 or 2x = 7 + 2 = 9 ( divide both sides by 2 )

x = \frac{5}{2}

x = \frac{9}{2}

Find the equation of the line with Slope = 6 and passing through (5,38). Write your equation in the form y =mx+b
laiz [17]

Hello.

We have:

  • A point that the line passes through
  • The slope of the line

Plug the values into the Point-Slope Formula:

\mathrm{y-y_1=m(x-x_1)}

\mathrm{y-38=6(x-5)}

\mathrm{y-38=6x-30}

\mathrm{y=6x-30+38}

\Large\boxed{\sf{ \ y=6x+8}}

I hope it helps.

Have a nice day.

Gabriella swims 2 laps per minute. What is the associated rate? ___ minute per lap
Leokris [45]

Answer:

The answer is D.

Step-by-step explanation:

It is given that Gabriella swims 2 laps for 1 minute. So in order to find how many minutes did he swim for each lap, you have to divide it by 2 :

2 laps = 1 minute

2 laps ÷ 2 = 1 minute ÷ 2

1 lap = 1/2 minute

= 30 seconds

Test :

Gabriella swim 1/2 min per lap. So if he swim 2 laps, you have to multiply it by 2 :

1/2 × 2 = 1 minute
