The temperature falls from 0 degrees to Negative 12 and one-fourth degrees in 3 and one-half hours. Which expression finds the c
ANEK [815]

Answer:

The expression used to find the change in temperature per hour is Algebraic expression

Thus per hour; the temperature falls at the rate of - 3\dfrac{1}{2}^0

Step-by-step explanation:

A temperature falls from 0 to  - 12\dfrac{1}{4}     in     3\dfrac{1}{2} \ hours

Which expression finds the change in temperature per hour.

From the above given information;

The initial temperature is 0

The final temperature is  - 12\dfrac{1}{4}  

The change in temperature is \Delta T = T_2  -  T_1

\Delta  T = -12\dfrac{1}{4} -0

\Delta T = -12.25

Thus;

-12.25 ° = 3.5 hours

To find the change in x°   per hour; we have;

x°            = 1 hour

The expression used to find the change in temperature per hour is Algebraic expression

From above if we cross multiply ; we have;

(- 12.25° × 1 hour) = (x° × 3.5 hour)

Divide both sides by 3.5 hours; we have:

\dfrac{-12.25^0*1 }{3.5}=\dfrac{ x^0 *3.5}{3.5}

x° =  - 3.5

x° = - 3\dfrac{1}{2}

Thus per hour; the temperature falls at the rate of - 3\dfrac{1}{2}^0

let's solve :-

=》

{m}^{2}  - 10m + 24

=》

m {}^{2}  - 6 m - 4m + 24

=》

m(m - 6) - 4(m - 6)

Which ordered pairs are solutions to the inequality y−2x≤−3y−2x≤−3?
alukav5142 [94]
Y - 2x ≤ -3y - 2x ≤ -3

y - 2x ≤ -3y - 2x
y + 3y - 2x + 2x ≤ 0
4y ≤ 0
y ≤ 0

-3y - 2x ≤ -3
-3(0) - 2x ≤ -3
-2x ≤ -3
x ≥ 3/2

One of the solutions to the inequality is (3/2, 0)
