7 0

Step-by-step explanation:

8x² + 8x - 21 = 0

8(x² + x) - 21 = 0

8(x + 0.5)² - 23 = 0

8(x + 0.5)² = 23

(x + 0.5)² = 23/8.

Evelyn can run 5 laps around the track in 11 minutes. If she runs for an hour, how many laps will she run?

iris [78.8K]

Answer:

27 laps

Step-by-step explanation:

So first step is to work out how many times 11 fits into 60

$\frac{60}{11} = 5.4545455$

Then you would times that by the number of laps which is 5

$5.454545455 \times 5 = 27.27.....$

So it is 27 laps as .27 of a lap is not a complete lap

Answer:

Smaller x value = -1 and y = -2.

Larger x value = 1 and y = 2.

Step-by-Step explanation:

x^2 + y^2 = 5

y = 2x

Substitute y = 2x into the first equation:

x^2 + (2x)^2 = 5

x^2 + 4x^2 = 5

5x^2 = 5

x^2 = 1

x = ±1

So y = 2 * ±1 = ±2
