Answer:

The temperature decreased by 9 °F in <u>6 days.</u>

Step-by-step explanation:

Let the number of days it takes for the temperature to decrease by 9 °F be x.

Given:

Average daily temperature decreases by 1\frac{1}{2} °F.

Decrease of temperature in 1 day = 1\frac{1}{2}= 1.5 °F.

∴ Decrease in temperature in x days is 1.5x.

Now, as per question, decrease in temperature in 'x' days is 9 °F.

Therefore, 1.5x=9

x=\frac{9}{1.5}

x=6

Therefore, the temperature decreased by 9 °F in 6 days.

Write an equation for the line that is parallel to the given line and passes through the given point
Evgesh-ka [11]

Answer:

y = 2x + 2

Step-by-step explanation:

The equation ofa line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 4 ← is in slope- intercept form

with m = 2

Parallel lines have equal slopes , thus

y = 2x + c ← is the partial equation

To find c substitute (3, 8) into the partial equation

8 = 6 + c ⇒ c = 8 - 6 = 2

y = 2x + 2 ← equation of parallel line
