If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am. What was the beginning temperature at 5:00 am if the temper
arlik [135]

If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am.  the beginning temperature at 5:00 am if the temperature at 9:00 am was -10.f is 18.f.

<h3>Beginning temperature</h3>

Dropped in temperature=7.t

Number of hours= 5:00 am to 9:00 am=4 hours

Temperature at 9:00 am=-10.f

Hence:

Beginning temperature can be calculated as:

Beginning temperature=(4× 7) + (-10)

Beginning temperature=28 + (-10)

Beginning temperature= 18.f

Check:

Since  temperature dropped by 7.f each hour from 5:00 am to 9:00 am

which implies that temperature  7.f dropped for 4 hours.

Hence:

18-7-7-7-7=-10.f

Therefore If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am.  the beginning temperature at 5:00 am if the temperature at 9:00 am was -10.f is 18.f.

Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? Determine the solution set algebr
almond37 [142]

Answer:

(5, 0 )

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 15 → (1)

y = 8x - 40 → (2)

Substitute y = x² - 2x - 15 into (2)

x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )

x² - 10x + 25 = 0 ← in standard form

(x - 5)² = 0 ← in factored form, thus

x - 5 = 0 ⇒ x = 5

Substitute x = 5 into (2) for corresponding value of y

y = 8(5) - 40 = 40 - 40 = 0

Solution is (5, 0 )
